Player Experience Highlights
Community Insight:
The layout for this app is not complex. Please update to support landscape in iPad. Enjoying the iPhone and AppleTV versions.
Great but tired of the quacking sound.
We have played this game on several apps and, by far this is our favorite one! The separate panel for candidates (notes) is most helpful, and the fact that it doesnt block wrong entries make it much more challenging, and more realistic. We do have one request. We wish it would let you review the completed puzzle when finished before closing the screen. We like to see the completed picture to relish all our hard work – just for a few seconds before moving on. Excellent layout and format is easier on our eyes. Thanks.
Exactly what we were looking for in a Sudoku app! The Apple TV version is great too.
A llot of other net sudoku games immediately let you know when youve misplaced a number. This game doesnt and you go on your merry way till you are cornered and have to retrace your steps to find your mistake.
The impossible level isn't all that difficult but we like to play this game once in awhile.
This has become our go to Sudoku game. We do the daily challenge puzzles every day. Keeps us sharp. Great game.
Never played sudoku before this game because it seemed to difficult. Now Im playing daily.
Finally a non-competitive sudoku app. No timer, no points, no pressure. A clean layout that does NOT require switching between note and normal modes. They each have their own keyboard. Ive deducted a point for the false negatives. Puzzles Ive solved, but the app wont recognize the win because our solution doesnt match the app makers. Irritating.
When filling a number it should remove the notes that conflict with the new entry. Impossible level should be more difficult.
After you enter the last number the timer keeps county and game continues. You have to go to menu, exit current game then go back into it. There will more the one number in red even that number is correct. If you re-enter the numbers in the same location then the game will end.
We are playing on appleTV. Twice now we have completed puzzles and been told theres a mistake somewhere in the grid… Except there isnt, and ive got screenshots to prove it. It seems clear the app is written with a single answer for each puzzle rather than testing a solution based on the game criteria. It is very frustrating to spend time on a hard puzzle only to be told your correct solution has a problem.
If we say we like the game, or just close the prompt, it asked the next time we play to review the game. If we say we dont like it, it never asks again. Id think apple would have a set policy to encourage accurate reviews. Also hard was too easy but impossible was literally made wrong and unsolvable. The fewest hints possible are 17, hard mode has 32. We do t want to know if we made a mistake but cant turn the feature off. Piece of crap game.
We like your game. Although we haven't tried a great many sudoku game apps, we can see that this is one of the best. Many thanks. We like playing the game without using the pencil — trying as much as possible to remember the set of available numbers for each of the empty cells. We are not good at memorizing and sometimes it takes almost an hour to complete a game, but it is more fun for us. We have only a couple of suggestions which we hope you would take into considerations for your future update. 1. Status bar: we think people would like to be able to check on the time, battery status, etc. Without having to end the game app. Maybe you can leave it up to the users by adding an option that toggles the display of the status bar on and off. 2. The Impossible level: Well, well, the games in this difficulty level are not nearly impossible. A little too easy, actually. We have played a few dozen games so far but we could solve every one of them without even having to use the pencil. We would like them a little more straining for the brain. That's all. Thanks again.
Having tried numerous sudoku games, he only negative for the games is that the number doesnt go gray or get shadowed, or something to notify you that the number has been used in all squares. However, we took one more star off of the continuous reminder after ever game to rate this product with no option not to.
Ive had this app for awhile and we really enjoy it. But recently its been freezing after only one move and all you can do is close the app. However, reopening it, it will still freeze.
Sudoku games are our favorite. The controls are good as is the graphics. Don't be afraid to load this game on your device. We highly recommend this game for anyone who loves Sudoku.
Great version to play. Feels very nice.
We have played many Sudoku games, and found the ideal game some time ago. Unfortunately the developer stopped supporting it. This game has one essential for us, TWO number pads for choosing what goes in the cell (one for penciling, and one to mark a finalized number). This way you never have to guess which mode youre in and fill the grid in faster. BUT, the game still needs some basic work: 1. The game doesnt recognize that you have finished a grid (or doesnt always). Perhaps this is because we have many of the hint features turned off, and it is some sort of bug, but at the least you want the game to acknowledge completion. 2. It is either Sounds Onor Sounds Off, no discrimination between effects and music. We hate background music in our games, but we like the feedback of sound effects. 3. Finally, it would be nice for game to highlight row and column you have selected, when you choose a specific cell. With these mods, this game could become THE five start Sudoku.
Back in the old Palm Pilot days, there was a sudoku version that updated the "notes" when you completed a field. So if you had the little 2 selected and then completed a nearby box with a 2 that rendered that note not an option in the other field it removed it automatically.
We enjoy that there is an "impossible" level that really challenges mores than other sudoku apps we've tried.
Best Sudoku game we've found and we've played A LOT!! Love it.
Best Sudoku game we have found on App Store.
Nice app. Sudoku is simple, but they did a nice job with presentation.
We like how easy it is to leave notes. Most apps make you push the tiny pencil icon and put it in a place where you can accidentally make an error by pushing a number next to it. It saves a lot of time just having another set of numbers on the side for notes.
We really like the control scheme that this app offers compared to most other apps we've tried. There is still room for improvement but we've stuck with this version for a few months now. We think the stats should also count games completed in the daily challenge and if you pay for the app the suggested other apps should no longer display on the app at all.
We really like the layout and features but for some reason it doesn't save all the stats and seems to record them on a whim. Our best scores are nowhere to be found. Also, when selecting the difficult or impossible levels, the scoring for difficult will be labeled normal and for impossible will be labeled difficult as if it's…impossible…to actually play the impossible level. If it matters, we're playing w an iPhone 6.
We havent been playing this game very long and at least a quarter of the puzzles Ive done are bad. Multiples of the same numbers in rows. Whats the point if these puzzles are not right to begin with.
It's a good sudoku game. We really like it, but… We've solved 2 "impossible" puzzles multiple times but it won't credit us the "wins". That's a little irritating. We like the different difficulty levels that we can choose based on our time available to play.
This game is a great experience if you are good with clear numbers. We've made sudoku contests and we always win is a very good app with great entertainment if you like numbers.
Cool, we find smarter when playing this game, it forced us to think. The game is excellent design, easy to use. We always play it as free time, it's fun to win. We give 5 stars. Thanks.
We recently got a new apple device and downloaded this app. We were amazed as to all the new content to this app. We love this app so much. Keep the updates coming…great app. Many thank.
This is a game with a simple interface but very attractive. The game has intellectual and entertaining. We love this game.
Love this app but sometimes the game won't let us play music at the same time.
Good app for sudoku, but we've seen better.
We really enjoyed the puzzle game. This game reminds us of the time in school. We used to play with his friends. This game is also very interesting. Thank you.
Very good app, so entertaining and good looking is very intuitive and easy to use and great sound totally recommended.
Very good puzzle games, compared with the same type of game, the operation is more simple, more beautiful picture, playability stronger, five-star praise.
We were looking for a sudoku game just like this and it's the great choice. Lots of fun and very nice game. This is the best game we've ever played.
Fantastic we enjoyed playing the game …. We have a lot of other games before but we were captivated by this game … Well deserved 5 *. Thank the developers …. Sure we will introduce friends to play a lot.
We often play it on computer and now we can play it on our phone. Great.
We're addicted to this game. We were a big fan of sudoku. Our mother taught us how to play sudoku. When we saw uncle play this game, he recommended us this game. We loved it. We don't care if adds come in the middle or asking to rate in between.
Our money is actually accounted for now. PocketGuard is an incredible service. We LOVE this app.
Best version of Sudoku so far, really love the woody background, got this app from our friends. Very good game to pass your time and a mind trainers for you, love it.
The classic game but still always interesting and engaging. Boost thinking and intelligence. Great app, we rated 5 stars.
This is the good app. We think it's very easy to use and we love it. Tks so much.
A fantastic game, we enjoyed. We used to play at leisure with friends, it helps us more comfortable. It has nice interface, simple gameplay with new people. Good game.
When the game became popular in the West we were one of the first to understand it and it is very addictive many years ago we did it in the newspaper now we do it every day in our cell phone is the best with different levels we like numbers.
We are a big fan of sudoku game, it's great that we found this app. We could spend all day playing this game without knowing bored. Thank the developers.
