Player Experience Highlights
Community Insight:
This is a solid version of your traditional sudoku. Very easy to use.
Over many years Ive gone through all 1000 games multiple times. Ill take a year or more off and start up again. Not possible to memorize any of the games. There are about 50 games in the Expert category that take a computer aided solve. Coloring and xy axis and many crazy solving techniques.
Very easy to navigate and play game. No annoying ads! Love it.
Easy to understand and has a great option for notes.
See title. No obtrusive ads, just game.
We are dxd with Alzheimers and we use your puzzle to monitor our memory/brain. The good news based on it is: Puzzle + infusions reports status steady.
Minimal ads, just a banner on the menu screen. No interruptions during games! No annoying in-between game ads! Simply the game. The options are nice and easy. You can play each level with little cheats or not. Super addictive and great.
Its a common game so what are you looking for? Ad free, aesthetic design, intuitive play. This by far the best version on the market and has been for some time.
This games is great. Its also very relaxed with no pressure and no ads. Thanks.
Big fingers. Small buttons. Could you make the number buttons at the bottom bigger. There is space. Hex.
Plain and simple, glitch free. What more does one want.
We enjoy this game more than any other sudoku game we play.
Bonitos colores y rapidez en la insercin de los nmeros mejor que otros Sudokus.
Very pleased with the simplicity of this entertainment app.
We love the note feature!! You can tell what number it its by the position in the box. Ive downloaded quite a few other and we always keep coming back to this one.
We like the fact that the right numbers are yellow and the wrong ones are red. We feel like it helps a lot to become better.
Been using this app for many years and its very user friendly. Very easy to read.
Clean & simple. Nothing gets between you and the game. Limited yes, yet great for casual play and taking a break.
Easy to use. We can challenge ourselves on time or on lack of errors. Big numbers so easy to see/read.
Love playing it when theres down time.
Some of the hard games are quite hard, but we also enjoy the expert ones as well.
We like that you have unlimited games to play after you solve each one.
Great challenging yet interesting apps.
We have been playing this App for a long time. Works great and never crashes.
What a wonderful app that is just the puzzle. Ive not mastered (let alone tried) the hard level. Its so nice to just go through the puzzle without interruptions like ads and failures. We go at our pace and if our life interrupts us we take care of what we need to. Then when we have free time we go back and continue on where we had stopped. Thank you for giving us a game we can play on our time. Ive not beat our best Easy time since the first day we played it. Thats reason enough to try every day when we have time. We never had a regular news paper delivery. We never had played this much at all. Im thoroughly enjoying this.
Fun classic game with No obtrusive ads.
Great game. Keeps your mind sharp.
Highly addictive and challenging. Keeps our neurons firing.
We have been using this app for years. It is our go to Sudoku app.
No ads. No wifi needed. Amazing. Our favorite app.
Fun, we are at the Expert level. Good mental challenge. Even Doctor recommended Sudoku for mental act. Good game. There may be a problem in computing the game aversges as it only drops by a couple of seconds regardless of the time.
Our favorite of the sudoku games. Easy to use and love the notes feature.
Challenging but not as difficult as the pencil and paper version. Good for relaxing.
Play this game all the time. Love it.
Love this format and of course the game.
It is very good. It allows you to change the difficulty at will, a very handy feature when it comes to sharpening your brain.
Fun fun fun. Great game to keep brain engaged and enjoy challenges.
Clean interface, easy to play, mechanically speaking.
Been using this app for a long time, and no matter how many other sudoku apps we try, we always come back to this one.
Challenging levels that keep our brain in a problem solving mode. Ive had this game for a really long time and unlike other gamesit hasnt evolved to display irritating ads that interrupt or delay play. Ads are small banners at bottom of screen and you barely notice them. Kudos.
Simple to use. Nice time passer. No ada which is much appreciated.
A good game challenges the mind to excel. This does just that.
We like how it lets us take notes on difficult puzzles.
We like Sudoku. This app has helped us improve because if we accidentally make a mistake the number turns red. We enjoy playing with a system to keep us on track.
We have hours of fun playing this game.
We love this game! Ive had this app for years and we love it! When we need a Sudoku fix this game app doesnt disappoint.
Ive had this app for years and still love it. We also like that the ads they show are not obnoxious. No sudden sound blaring from a quiet game, no ads that you have to click through multiple times. We dont need to watch a video and then click multiple times to see whats being advertised and we still notice them. They only show up after you finish a game. Other apps could take notes on that. Our only request would be a dark mode for night time.
No fuss with a few options to give you everything you could want for sudoku.
We like how the add banner at the start is very unobtrusive, and then no adds once you start playing game. The game has all the options we need, and we really like being able to choose whatever skill level we want.
