Satori Sudoku Game Reviews

Love it!. Fantastic app! It was the first game app I bought when the app store first opened. Since then I have bought, played, tired of and deleted countless others, but I still play this one almost daily. The developer did a great job of creating a perfect sudoku app!!!

Great App For Sudoku Lovers. Being a sudoku lover I installed this app when I got my first iPhone over two years ago. I've installed 100's of games since, but this is the only one I still play on a daily basis; and I typically play it multiple times a day. The ui isn't perfect, and it can be hard tapping the right squares, but given that sudoku requires a 9x9 grid, and the screen is only so big, it's hard to imagine how it could be done better. The only suggestion I have is to support landscape mode. Display the board on the right and the number pad in the left -- my right thumb can select the square while my left thumb taps the digit. There have been many times when I was sure I had a solution that didn't validate, or a puzzle which appeared to have multiple solutions. But after checking carefully I always found I was wrong. In the probably 1000+ games I've played, I haven't found a bug yet. Well worth the 99 cents.

Much better now. Best sudoku on the iPhone. I gave this four stars earlier despite some problems with the puzzle generator as the developer emailed me that a fix was coming. As of version 1.2 it works perfectly with great symetrical puzzles and an awesome UI.

Great Sudoku app with a nice and simple interface.. I had a free sudoku app on my ipod touch that I had always used. Yet I never really liked the layout of it and the backgrounds always seemed to get in the way. I like this app's simple yet effective presentation. I also like the fact that there is a number pad right on the interface which also comes in quite handy. Definitely recommended for any sudoku fan.

Some serious flaws. A decent version of sudoku and reasonably priced, but there are some serious problems with it. First of all, the way to fill in a cell is a little awkward, requiring double-taps. (Single taps are used to "pencil in" possibilities.) More seriously, most of the puzzles it generates have multiple solutions, making it impossible to solve them without guessing. Some of the puzzles appear to have a *lot* of solutions, meaning you have to start guessing early on.

Ok, but disappointing. I liked the interface, and the price was right. However, the puzzles usually cannot be solved by logic alone, which is a serious flaw with Sudoku. It wouldn't be the first time I have come across puzzles like this, but I never paid for them. I can only hope that an update comes out to improve this. I would give it a 2 if they don't, and a 3.5 if they do. DO NOT GET THIS UNTIL THEY UPDATE IT!

New Version just came out!. Love the new version, puzzles are much better.. looks pretty and looks like they made the markers a bit bigger. good to see the dev is listeneing to comments. pity all those comments for the 'old' version are still in the store.. they dont really apply anymore. I love that the keypad doesnt cover the board like on some of the other games (how the heck are you supposed to see the board if the keypad is touching it?? those versions are lame) this is very well thought out. To darkest - game difficulty def gets harder when you change it in options. Did you actualy play the game? LOL

Pretty good, but....... I like this app but there's just one problem, when you change the difficulty level, it doesn't do anything. It's just as hard, even when you press the "new" button. It would be great if someone would tell me what to do. Have any of you guys seen the dark knight? Yah, that was the best movie I've ever seen. Peace out.

Includes games that have multiple solutions. I found this version of Sudoku to be very frustrating because: • It includes scenarios where there are multiple solutions, which makes even the easiest puzzles very difficult to solve. • There is no undo feature • There is no way to totally clear the board if I get totally lost I've deleted it, so I just wasted $1.99 - too bad the App Store doesn't have a refund policy.

Best Sudoku out there with the 1.1 update. Bought it initially because of the clean interface, I like the use of one button for making notes and filling in. Also nice because the number pad doesnt cover any part of the board which is nice when you are scanning for your next move. With the 1.1 update puzzles are unique now. Wouldn't mind a timer, but definately the sudoku to buy now.

Great app. I use this every day and it has always worked great. Good features and very clean. I have tried a lot of Sudoku apps and this is the best. Two requests - make start over an option rather than just "new" game, and lose that stupid flashing star you added on the last update. Otherwise great job and keep it up.

Sudoku Lovers Dream. I have tried several sudoku apps. This is my favorite. The interface is pleasing and the game runs very smoothly. Many helpful options. Easy to use and with a seemingly infinite game generator, this app will remain on my I- Phone indefinitely. **Only suggestion:** Please make the pencil marks a different color than the finished numbers that are entered. They are both blue. It would be helpful if the pencil marks were in a different color. Thanks for a great app!

Perfect. I like the complexity that builds in the game, considering there are lot of free versions out there it is hard to convince to buy this app. But I still recommend it for the price. Read the other reviews and you will know

Good Interface - Very DIFFICULT puzzles. I like the interface, but the puzzles are VERY difficult (even on the easy level). I've played a lot of other sudoku games and can usually get them on their most difficult level. But I can't get some of these even on the easy level. I've also encountered some puzzles that have multiple correct answers. Most every puzzle requires using pencil marks or using the "cheats" provided. It would be better with a timer also. On the positive side, it is very intuitive to use and the graphics are attractive.

Wonderful. My first review was only 2 stars due to the now fixed "broken puzzle" problem. The controls are easy to use and nothing becomes obstructed. Pencil marks are awesome. My only wish was that the verify feature would work mid-way through the puzzle not just at the end. Oh, and Shacallie or whatever, I think you got your apps mixed up because Satori has always been this price. Well worth it and beats the free app tons.

Great Interface & Horrible Puzzles. As all the reviewers here who have played this game will tell you, the puzzle generator here is broken. I've tried a few times on normal level and I keep getting puzzles with multiple solutions. To test this yourself, enter a puzzle at any online sudoku solver. You'll get multiple solutions which are extremely frustrating. My generic, Verizon Sudoku cellphone game generates better random puzzles than this one. The interface is very nice so I hope the developer fixes the problems.

Great, Clean Interface. I think this is a great Sudoku. I understand some of the reviews complaining that games do not have a unique solution. But for me the interface is far more important than the sudoku purity. I'm guessing it's a hole in his algorithm and may be fixed at a future date. I'm just glad I don't have to muddle through bad graphics and extraneous visuals but can enjoy a clean and highly functional interface. My only complaint is that I would like to be able to reverse the logic and set the number first and tap on individual grids to assign that number... maybe a toggle to go back and forth?

Good Interface, So-So Puzzle Generation. Comparable to the portable sudoku interfaces I've tried. (To give you an idea, I've tried the dedicated electronic sudoku games--this plays better. I've also tried Brain Age DS, which is better than this, but doesn't run on an iPhone/Touch.) However, several puzzles have had multiple solutions, so the puzzle generation needs work. Still, a good value for this very casual sudoku player's $2.

awful puzzles. Game play is pretty good but the puzzles are terrible. Out of 10 puzzles I've played, 9 have had multiple solutions with one having at least 8 correct solutions. Increasing difficulty level makes the puzzles have even more correct solutions. The publisher needs to correct this flaw. Game is unacceptable until it is fixed.

Well Made. "Digital" sudoku is hard to do right, but this version does a good job. It is easy to scratch in your possibilities (press the number once for a scratch-in and twice for your answer), and it uses hints that actually are just that - hints. For example, one hint will show you all possible placement of a number. Good job, good price.

Very basic flaw. I echo the other reviewers on the flaw that the program allows for multiple solutions in a puzzle. I have used other Sudoku programs on the Palm and iPhone, and this is the first one with this problem. The other major miss for me is the lack of checking as you go. You can only check once you have completed the puzzle. I would recommend another application besides this one for Sudoku.

1.1 fix is awesome. well, i have to say i was impressed. took em a bit to get it out to us, but this fixes all the complaints ive seen so far. no more 'multiple solution' puzzles, and they are really nice looking puzzles. better than that 'free' one where the difficulty hadnothing to do with difficulty,but just numbers left to fill in? this is the best sudoku i've tried for iphone (I've tried 4)

Good and goign to get better!. Well, I noticed that right now, sometimes puzzles will have more than one solution. Contacted the author, and he said he just submitted a new version with a fix (as well as making markers better). So, a great app is only going to get better. Love the interface, so clean and usable. Certainly the best sudoku for the iphone.

Sudoku satori...glitch?. Don't know if mine has a glitch, but even with options enabled I haven't been able to solve any puZzle in EASY!! Nor has my husband who is very good at sudoku

Almost perfect. I really like the design and user interface, it does make a difference. However I would like to see some improvements on generated puzzles. On normal level by the end of the game there are too many double cells left in several 3x3 boxes, where it doesn't mater what number you write down. Which makes it less interesting, imho.

Excellent interface. Well done. Larger "pencil mark" numbers are an improvement. This Sudoku is now easier to use, and therefore better, than the one for $7.99.

Fixed!!!. I wrote an earlier review panning this app. Now I have to change my tune. It used to be that the puzzles had multiple solutions. Sudoku's are only supposed to have one solution. With the recent updates, the author has fixed this. Great application at a great price. No annoying music. No tedious splash screens. Just a nice clean interface, great annotation system, and some useful tools for solving those tough ones. Only things missing are: 1) A book mode, where you can enter Sudoku's from another source and 2) A command to clear the puzzle so you can restart it if you screw up.

The best sudoku for Ipod. With the puzzle generator, you'll never have the same sudoku twice, not to mention infinite sudokus. This is the cheapest Sudoku game with a generator you can find. It has a great interface as well. Although I've had some Sudokus where there was more than one way to solve it and still have the sudoku be correct. Anyway, don't bother with other Sudokus, I've compared them all and this seems to be the best bang for your buck for sudoku for your Ipod.

Great entry in the genre. Overall a very great app. Sometimes a little tiny for my eyes (that's what reading glasses are for) but I can't say enough about the great interface. Having the numbers in keypad format surrounded by the options is a very nice layout. I'm not a good Sudoku player so the "easy" might be a bit simpler to help beginners. I'm sure the other levels are great. Has some nice assist features (highlight shows all the places a particular number can still be played; auto shows only the numbers than can still be placed in a cell) - excellent app. Thanks!

Great Interface, Great price, BAD PUZZLES. I chose this app because of the interface, and I still think it's the best one for the price. However, the puzzles are invalid and frustrating (unlike real sudoku puzzles) and I will waste no more time on this app. The only reason I don't delete it now is that I'm hoping the developer will update it with a better puzzle generator. Otherwise, I will look for another app.

Good App. The latest update on this app has greatly improved the difficulty level and now offers some genuinely challenging puzzles. I would still like to see some sort of scoring/time keeping element to the app. Different color options would also be nice other than plain white background which strains the eyes. The elements at the bottom take up a lot of space, too, making the board a little smaller and also a little hard on the eyes. These are subtle ares that could be refined, but overall this is a solid 4-star app.

Best $1.99 I've Spent?. Probably. There was this bottle of wine when I was 17, but... another story. This is a clean, smooth working interface; it is challenging and fun. The only way you'll go back to paper games is if your iPhone battery dies and there's no plug around for you to plug back in so you can play so more.

Ok app, but lacks features. App works ok for price, but wish it had a "check your answers as you go" or "hint" feature like most online games so that you don't get to end of game and have to undo everything because of one mistake. The "verify" feature only works at end of game.

Problem fixed -- now it's really quite nice. Version 1.1 appears to address the problem with puzzles not having a unique solution, which now makes the game very usable. Things I like: - Clear and clean board with very readable digits (the subtle white/gray shading is a nice touch). - Very straightforward interface: single tap a digit to add/remove a "pencil mark:, double-tap to put/remove in the actual value. The "keypad" is always in the same position and doesn't cover the board. So far, the most fluid approach I've seen to Sudoku input. - Explicit "check this solution" button (I prefer that over the game automatically checking when I enter my last digit, in case I mistype). Things I miss: - A timer. Notable features: - "Auto" mode disables keypad buttons when first-order analysis makes a value invalid. - "Highlight": For a given digit, show all locations that could allow that digit after first-order analysis. All-in-all quite a nice implementation for $1.99. I think it deserves four stars. With an added timer and perhaps a little polish on the non-board part of the interface, I could give it five stars.

Needs fixed.. When it works, it's one of, if not, the best sudoku apps in the app store. However, I have had issues with the puzzles this app generates where a puzzle either has no solution or the numbers are wrong and force you into putting more than one number in one box, even when you've done everything perfectly right. PLEASE FIX THIS. If this was fixed, I'd happily recommend this app.

Not an impressive algorithm. Having paid for paper puzzles and playing a number of electronic Sudoku puzzles this one made me realize a nice interface is only part of the problem. The interface here is excellent. The algorithm for puzzle generation is quite bad. Even simple puzzles are sometime solveable only by brute force. Needs work, if an update improves it I will write and updated review.

Good App. This application works well and doesn't waste time with unimportant frills. The negative reviews I've read might make sense if the app was priced at something like $20. What do people think they're going to get for $2?

The best sudoku. This is the best sudoku game out there. The value is fantastic. Easy interface. Just hit a box and then a number and it is penciled in. Double click the number and it is entered into the box as a sure answer.

Multipule solutions. I purchased this App listening to how well the interface was, dismissing the reports of broken puzzles. Sadly I should have listened. Every puzzle I've gotten since purchase have had multipule solutions. Very disapointing. The interface is quite well done, but the broken puzzles rob all fun and make the game frustraiting. It looks like they come up with the puzzle by taking a full puzzle and pull X random numbers depending on difficulty. You can't do that and guarentee solvable puzzles. Don't buy this unless it is updated. I regret buying it. All I can hope for is a future update that makes it playable.

Very good (update). I also wrote an earlier review bagging the app for multiple solutions per puzzle and asymmetrical puzzles, but these issues have been fixed. I agree that having the ability to create your own puzzles would be nice, as well as the ability to clear the screen (but continue with the same puzzle). I also think the hard level should be more challenging, as those only take 8 to 10 min to solve. Since this is turning into a wish list, it would also be nice to have a timer and *maybe* the ability to compare/compete with other users? Just a thought... :) Even without these additional features, this has now become quite a nice Sudoku app.

Wonderful Application, Responsive Developer. This one does exactly what it says it will, and the developer has been very responsive to customer feedback and regular with updates. Good show. The one thing I'd change is to have a switch to choose whether single-taps enter answers or pencil marks. Double-tapping to enter answers has been a bit of an adjustment for me. But it works well and I really don't consider this a serious deficiency, just a difference of opinion about how the interface would work best.

Puzzles don't have a unique answer. Does well what it does, but 2 stars knocked off cause puzzles don't have a unique answer. That's a major turn off for some (me). 1 star knocked off cause there aren't advanced stuff like "pencil in" to test solutions without compromising the board, and clicking on a cell to highlight it's column and row (useful for quickly checking out possibilities visually).

Great interface. Puzzles useless. Please fix it and provide a free update. I want my money back... the actual Sudoku puzzles are a waste of time. They are machine-generated, and even some of the "easy" ones cannot be solved except through trial and error. When I was able to solve one (often with a "harder" setting), it was easy to see that there were multiple solutions. In spite of the excellent interface (no annoying sounds or hokey animations--just play it!), this does not overcome the fact that the puzzles themselves are both ugly (non-symetrical) and terrible. No stars for you, Mr. Kozan. Please go back to the drawing board, get some good puzzles, and provide us all free updates. Thanks.

Excellent App. This is the absolute best sudoku app that I have been lucky enough to play. The controls are very intuitive l, and just love the auto and highlight features. The shake to restart was very convienient and even took away some frustration when I was stuck. Overall, a wonderful app and I look forward to more exciting things from this developer!

Not There Yet. In order for a $1.99 app to compete with the free ones out there doing the same thing, it needs to have a little more robust functionality, and this one doesn't quite deliver. For starters, the difficulty ratings are inconsistent and indistinguishable between "normal" and "difficult", and even on the most difficult level, the puzzles are far to easy for the advanced Sudoku puzzler. Users serious enough to pay expect a higher degree of difficulty and to leave the free apps to the ameteurs. This app could also benefit from some simple scoring/timekeeping elements for the competitive player to track their personal bests. An undo button would be nicer than the cheater elements, so you can backtrack to before your mistake was made instead of just cheating to see the answer. Finally, something at the end of a successfully completed puzzle would be nice rather than the bland statement "congratulations, you solved the puzzle." The overall UI is good so I think this one has promise but needs some work on the features.

Best Sudoku app!. I picked this one because the design looks the best out all the other sudoku apps. After the latest update, I've had no problem with the multiple solutions issue, and easy mode seems to be corrected with the right difficulty level (it's easy enough for me, as I'm fairly new to sudoku). Overall, an awesome app for the price.

Works well, purchased on sale for $.99 - Sept 29, 2007. I reviewed all the Sudoku apps in the store before buying this one. I'm not a Sudoku expert, so the game is challenging enough to kill 20 minutes. It works well and I haven't had any crashes. I think the initial state of the game should include the full 1-9 "pencil marks" for empty cells. For me, determining which numbers are not appropriate for a cell is part of the game play. The "auto-fill' button seems like cheating (it tells you which numbers are possible for each cell). Once it's turned on, turning it off takes away all the "penciled in numbers", even the user-entered ones. During auto-fill use, user changes to the worksheet ("pencil") numbers are over written and not kept. Otherwise, a good app.

Too hard, even on "easy". I bought this one because of the great reviews it got. I commute on the subway and enjoy solving the newspaper puzzles in under 20 minutes. This is not one of those. I have no use for it now. If I was stuck locked in a room for a few days at a time, maybe I might waist my time on this. The easiest level takes way too many guesses to solve. Who has that kind of time while commuting? I want my $ back, or please add some puzzles that are able to be solved under a half hour!

Nice graphics, great price, but not a true sudoku. To echo what everyone else says, true Sudoku needs to be solvable by logic and not guesswork. Even at the easiest settings there are ambiguous answers to the same puzzle. However, nice touches include: - Price: can't be beat - Can listen to music while playing - Graphics - User interface I would give this 4 stars if the logic issues are fixed.

My favorite sudoku app by far. I really like this one above the others however there are a few things I would like to see. 1. The current highlight mode shows possibilities, but if you have eliminated a possibility it still highlights. 2. Maybe a slightly harder difficulty than the current hardest. As I am getting down to 2-5 minutes per game with highlighting (I like fast lol). 3. Maybe a switch in the ui to turn it into solving mode where you don't have to double tap to put a solved number in. Because I find near the end of a puzzle I have to tap excessively to finish out the puzzle. This is just a wish list though. Still the best either way. Good work!

Bad and pointless update. This was a fantastic app for me. Every game was challenging on all levels. Now with the new update, the generated numbers aren't 'random enough' anymore. The given numbers show up in patterns that match up on opposite ends, if you get my drift. Think I'm gonna have to convert to another one. Tis a shame.

Great GUI, Logic Needs Work. For the price, it is a pretty good game. The GUI is clean, and the highlighting feature makes it very easy to see patterns for a particular number. It is also easy to add and remove pencil marks. The Auto feature only shows you the available numbers for a particular cell, but does not fill in the the pencil marks like other versions do. This could be a plus or a minus depending on your preferences. On the down side, the pencil marks are a bit small, although they are positioned in the cell so that you don't really need to read the number to know what it is. A timer would be handy so that you could see how fast you are going. The biggest problem with this game, however, is that there are often multiple solutions to any particular game. You'll often be in a situation where there is no obvious answer, and will have to guess at a number. I've found that my guesses are always right, and that there's always two or four open cells at the very end with identical pencil marks. This mars an otherwise fine game.

Solid Offering. The clean interface of Satori Sudoko is a pleasure to work with and the various levels of difficulty will provide challenge to players of all levels. The current version (as of July 16/08) does have a bug where puzzles can occasionally be un-solvable, however this issue has been addressed by the developer and an updated version should be available within days and should not be viewed as a reason to not buy this very reasonably priced application. Recommended for players of all levels.

Not worth the money. Too many bugs. Once you finish a game successfully, the continue button doesn't work, to start a new game, so you have to leave and the restart the app to play another game. Even when all the solutions are correct, it tells you you are wrong and won't continue. And I'm pretty good at sudoku, but even the easiest level can be really hard most of the time. Overall, not great, considering I paid for the app.

Good buy!. Awesome game! Great time passer!

Best sudoku in the app store.. I have tried a few sudoku apps and this is my favorite so far. Mainly because of the input method and the easy-to-use UI. try it out

Great App. Couldn't ask for more!

No, 1.1 didn't fix the no solution problem. Downloaded 1.4 and the first 3 puzzles didn't have a solution or the auto pencil was wrong. Worked fine before 1.4. So, back to one star!

So close. The interface is perfect. I wouldn't change it a bit. Unfortunately, the puzzle generator is poor. It generates puzzles with multiple solutions. It also generates puzzles requiring guessing to solve. This is a dealbreaker for me. Perhaps it can be fixed with an update.

Nice game layout...bad puzzles. As others have pointed out the puzzles do NOT have unique solutions. On my first two puzzles I arrived at the end to find that there were multiple correct solutions. This isn't just bad Sudoku...it's not Sudoku at all. This is a game of logic , not guessing. I see the developer has posted a note stating that he's working on a fix. Let's hope so.

Numbers too small. Need an electron microscope to read the numbers input (vs. the larger numbers that start the game). What an amazingly poor oversight. Waste of money until this is fixed.

pretty sweet game... pretty handy game... just like the one i play online

Doesn't make true sudokud. A sudoku only has one possible solution. So far, many of the puzzles I've solved had several (I've double-checked by moving numbers around and I can still get a "verified" answer).. Awesome interface, but what's the point if the puzzles aren't correct?

Poor puzzle generation.. While the interface is nice, it generates incorrect puzzles. The last three I played had multiple solutions. Granted, it is cheap, but not worth it. Hopefully they will release an update that fix the faulty generator. Until then, it's not worth playing.

Numbers too small. The interface looks good, but when you enter your numbers they're so tiny as to be impossible to see.

Well Done and Nice price. This program was well done and the price is great

Okay, but there are better Sudokus out there. Everything worked, but I didn't care for the interface. This is the first app I've taken off my Touch. :(

Love the interface. I really like the way this version of Sudoku was designed -- I agree with the multiple solutions gripe which is why I didn't rate it 5 stars, but other than that it's very well done.

Nice. I like it. Couldn't find a jailbroke or web app Soduko game I could be happy with. This game has done that.

Great App. This is the best Sudoku App for the iPhone. Really fun to play. Buy it now!!!!

Best interface. This really is the best interface. I love not having a separate pencil/pen interface. I really wish there was an ipad version.

Good sudoku app. I like this sudoku app. Does almost everything that a sudoku app should. Only thing I would want added is some form of help for if I get stuck.

frustrating. as others have said, there is no single solution to these puzzles, which make them next to impossible to solve. 2 stars for having a good interface.

Incorrect Puzzles!. Terrible sudoku app. The interface is nice, but it doesn't generate correct puzzles. Not one of the puzzles I have played had only one solution, and if the puzzles aren't correct, what's the point of playing the game? Also, you have to tap the number twice in order to select it for a space, which is very annoying.

Agreed - multiple answers makes for bad Sudoku. I was amazed to find that the first puzzle I solved had multiple possible answers. Not only that, it was an assymetrical puzzle. Not a huge deal, but not the preferred style. Nice interface, though. If he can clean up the puzzles, which is ESSENTIAL, it will be a very nice Sudoku app.

Good?. This is a good app and a lot of fun but it is a little to hard for me. They should add an easier option or more easy option.

Great app. Great price.. Very well thought out. The board numbers could be a little larger but other than that very well done.

Nice interface, but 2 of 2 broken puzzles. As most other users have noted, the puzzles don't have a single answer, which means that the game is not useful after a point. The interface is excellent and I really hope they fix the logic bugs. I can't recommend this one until it's fixed.

Unfolded mysteries. Nice UI and features but after attempting 6 puzzles, the puzzles do not solve. On 3 games the given filled in spots led to one solution but they would not verify. Needs more work. Wasted a dollar on this one.

multiple solutions ruin it. I agree with other reviewers. Sudoku should have one unique solution per game. This one has multiple/non-unique solutions. It ruins all the fun of a logic game!

Puzzles Don't Have Unique Answers. Love the interface but the puzzles are incomplete - In 4 out of the first 5 puzzles I tried, when getting to the end of the puzzle, each cell still had multiple possible answers!!!

unhappy. I was very upset that I purchased this item free a few weeks ago and then it asked me to update, so I did and the game just stopped working all together. Now I went to try to re-install on my iphone and they are charging $1.99.

Excelent. I like to play sudoku alot until my sudoku gadget that I got ran out of battery. This is the first and only sudoku app that bought and I love it. Great patch btw.

Worthless. Every puzzle I've played so far (three) have failed to have a unique solution. Sudoku is NOT supposed to be a random luck game. Each game is supposed to have one, and ONLY ONE correct answer! Don't bother. What's the point of a good interface if the game is broken?

Excellent app. Easy to use, and the difficulty slider is a nice touch. Overall, one of the best sudoku apps.

Invalid puzzles. Gemeates puzzles with multiple solutions, which is by definition an invalid puzzle.

Game stopped working.... I like the interface and quality of the game but it stopped working after I synchronized my iPhone with my Mac. (now I'm on a plane and I can't use it.)

Worth every penny!. Everything you could possibly want in a Sudoku program. Best $2 you'll spend, period.

Awesome. There must be so many sudoku games in the app store, so what makes this special. Visually is is beautiful, pleasing to the eye, and ability to generate millions of puzzles.

Sudoku. Great interface with countless puzzles. Great app!

Awesome App. This is the first app I paid for, and it's really a nice app. Simple, fun, and an awesome price.

Great app. The app lives up to its ratings. I just wish there was a "hint" feature.

Great. Once game is complete, the onscreen buttons for the completion polio don't function forcing a restart of the app.

Nice fix for puzzle generator. The 1.1 fix was exactly what this game needed. It still lacks some features like timed game, but it is now well worth the price.

PERFECT version for $1.99 - NO BRAINER!. Hmmm. $30 handheld Sudoku or This PERFECT version for $1.99 - NO BRAINER!!!!!!!

Great Job. Great interface for the iPhone.

BEST Sudoku for the iPhone!. This is the only Sudoku app you need for the iPhone - the interface is great and the price can't be beat. Easy to play and input, and great for novices and advanced players alike!

Has the best interface. I've checked out several of the Sudoku apps and Satori really has the best interface to playing the game. Great game.

Multiple solutions. The interface is fine, but the puzzle generator creates puzzles with multiple solutions, which most sudoku experts consider to be broken puzzles.

Slkcomm. Yes the game is tougher than some. My problem has to do with the error highlighting function which does not function reliably.

Love this version, will help pass the time nicely!. Absolutely perfect app for the iphone.

Incorrect Puzzles!. Terrible sudoku app. The interface is nice, but it doesn't generate correct puzzles. Not one of the puzzles I have played had only one solution, and if the puzzles aren't correct, what's the point of playing the game? Also, you have to tap the number twice in order to select it for a space, which is very annoying.

Bad sudoku. I want my money back. The good: * Absolutely excellent layout for the iPhone * Ability to take notes * Highlight and possibles feature The bad: * I haven't found a puzzle yet that had a unique solution. This is simply unforgivable. * Difficulty meter doesn't do much. Probably since there is no unique solution. Medium and full difficulty seem the same.

Multiple solutions. As mentioned by other users, the interface is great but the puzzles have multiple solutions.
