KillerSudoku App Reviews

While this app has promise, there is no way to notate the cells to assist in solving them. The help has basic information, but has a few buttons that should be included. I spent quite a few minutes of time setting up a killer sudoku game, saved my work and attempted to solve... while typing this review, I tried to "open" my saved game and it doesnt seem to exist. All in all, this game needs much work before any price is justified. As it stands, it should not have been released.

Its the only Killer Sudoku I could find, which is great, but it needs an update to enable the player to keep notes in the squares. Otherwise, the player is limited to easier puzzles. Please update the application! Other than that, the options are nice.

Until the UI is changed to allow multiple cell entries, this games not very playable. Wait for next release!!

I bought this despite the reviews because the image shown implies that you can make notes. I thought it had been updated. However despite the screenshot, it does not appear to allow note taking which dramatically decreases the game possibilities. If this gets fixed I would give it more stars.

If this game worked it would be worth to pay maybe 1.99 for it. But I am now absolutely convinced that it sometimes generate wrong killer sudokus. I want my money refunded and I dont know how to go about it. Tons of problems with this ap. Dont waste hot money.

This is a great game. I give 2 stars now only because the lack of a save feature. If this is fixed in an update, I will give it 4 stars

While I agreed with most of the previous reviews the game is much more playable with updates. You can now input multiple possibilities in any cell. The calculator function is unique and helpful! I wish there were harder killer sudoku levels though.

This is such a good app except for ONE thing ... The "save" function is basically useless. If you save or take a snapshot only your notations are saved, not your solved entries. I have to finish a puzzle in one sitting or it will be essentially lost. Love the calc feature. Its usable and has promise, but needs to be fixed. If Ive missed something and am just doing something wrong, please let me know. If thats the case, the help text might need revisions.

I love sudoku, but I didnt try killer sudoku until recently. I love it! The app auto saves my game when I exit or get a call. The calc feature is a great help and I also like the different ways to identify groupings. There is a pencil option. With different difficulty levels, it is a great game for those getting started, or people who already love the game. It also has traditional sudoku, too. I dont really write reviews, but was surprised to see the negative ones on here. I guess I bought it after an update. Its well worth the money, IMO!

I agree with other reviewers that this app seems to have mostly unsolvable killer sudoku puzzles, but Im still giving it four stars still because besides that, its perfect, and Im putting my faith in the developers to fix this problem since Ive now given them $2. Whats awesome: the price is worth it just to play clasic sudoku with the drag feature. You can drag your finger over as many square as you like and place notes on all of them with one tap, this is so amazing. And also, the classic sudoku seems to be more challenging than even expert on other apps, which I like because I sometimes feel like Im just going through the motions to solve some puzzles, but these seem to need more problem solving. All in all, will be perfect when they fix the unsolvable puzzle issue, but you can still enter your own puzzle in the morning to have with you in a more convenient way throughout the day.

I was disappointed that this app has so many bugs. I bought this for its Killer Sudoku option because Cool Sudoku has some difficulty retaining pencil marks. Well, this app does not retain filled in boxes. Complete the game before you close it or your efforts will be gone when you reopen. I tried everything -- saving the game, saving under different names, closing quickly, backing out, taking a snapshot (which only made the filled in boxes erase immediately). Huge drawback. In addition as mentioned above, the so-called snapshot feature which should help you return to a previous version, simply erases your filled-in numbers while keeping your pencil marks. Finally, the option to use colored backgrounds instead of dotted lines to differentiate the sections fails because they often put two boxes of the same color adjacent so you cant tell where one ends and the other begins. Giving the developer the benefit of the doubt, there must be something extra hard about writing apps for Killer Sudoku since the other app has similar problems while there are a dozen excellent apps for regular Sudoku. But this app currently has too many problems to use, perhaps they can be fixed in an update.

For years, I have been unable to fall asleep without doing sudoku. Killer Sudoku was always my favorite, but it was difficult to find. This app has saved me so much money and given me many nights sleep. Yay. Thank you!

Terrific app. The Killer Sudoku is a bit frustrating as many puzzles have more than one solution. Still well worth $!

SUPER addicted to this game!!! I play it all the time! I cant just watch TV and sit still so I play this while I watch and it helps me pay attention to the TV and still stay occupied. ... I would love it if there was some kind of reward (like points or something) at the end instead of just congratulations. ... But other than that, best app ever! 

I never review any apps I download, but this app really frustrated me. The reviews on this app are decent, so I decided to give it a try because I love killer sudoku. I was extremely disappointed with the interface and design of this app. I guess Ill just stick with the free Sudoku 2 app. Not killer sudoku, but at least it looks nice and doesnt have some unsolveable puzzles.

Ive had this app for some time now -- probably 3 years -- and I use it a lot. It does generate Killer Sudoku puzzles, and I havent found a better iPhone app for that as yet. However, it almost always generates Killer Sudoku puzzles with multiple solutions, which is very frustrating to someone trying to treat it as a logic puzzle rather than a guessing game. Also, the controls are awkward; it would be a lot easier to have two rows of numbers, one for pencil-marks and the other for actual answers, instead of having to constantly toggle back and forth between actual and pencil input mode. That said, I have not had the problems others have reported. I frequently take a phone call while solving a puzzle, and never lose any of my partially-completed solution. Ive not had it generate a puzzle with no answer. Finally, I use it so much because I love working Killer Sudoku puzzles, and havent found anything better for the iPhone as yet.

The interface is clean, though can be a little cumbersome at times, hence 4/5 for this. This is easily the best app Ive found for Killer Sudoku that Ive encountered, though. Oh...and there are some rare Killer Sudoku puzzles with uncaged numbers that make for an AWESOME challenge! Ive never encountered them outside this app, but that could because I havent really looked for them. (Itd be nice to have an option that only generates those types of puzzles.) I dont play regular Sudoku, so what follows is only with respect to the Killer Sudoku aspect. On multiple solutions: some logical patterns do result in multiple solutions, but thats the nature of the patterns. There exists such a thing as logical "dont-cares" & they result in multiple solutions; its a valid pattern. Failing to see the pattern or that it allows multiple solutions to exist could explain why some people are complaining about unsolvable puzzles.

I got this app a couple of years ago and I love it. I was surprised there were so many negative reviews. I have never had a problem with it. It is my go to app when I have some time to kill. For those who say they get completely unsolvable puzzles, are you sure you know how to play killer sudoku? I have never gotten one that is unsolvable with the random generator. I love this app!

There is a major issue with the killer sudokus with more than one solution. It is rather annoying. There is no problem with crashes though but I would like to see some more difficult killer sudoku puzzles. The four stars I stead of five is because of the multiple solutions to about half of the puzzles.

I loved this app, but it was hobbled in iOS 7, and now completely non-functional in iOS 8. What a shame - with a few bug fixes and iOS 8 compatibility, this could be a great app, but the developer has abandoned it. Look elsewhere....
