    I’m a long time Sudoku player. I looked high and low for one that had the option to reveal all notes for all cells at the beginning. This, besides one from an internet newspaper, has it. The newspaper gives you only one game per day. This one comes with every game if you choose that option. Putting down notes of possible numbers in a single cell is the most time consuming part of playing this game. This one saves you all that time. In addition, it lets you manage the notes...taking numbers off and putting them on. The hint feature is awesome. It takes you through each hint step by step in a tutorial way. Then to top it off, it applies that hint, if you want. Great game. It’s worth every penny....dollar!

    This app is brilliant! It's taken me a long time to find a free Sudoku app like this: it doesn't run ads during the game, it has a user friendly interface; it offers you hints when you need them and it actually keeps you on the right track, which is so helpful! All in all, a great Sudoku experience! So far, so good! :-)

  • Teaches you how to solve sudoku Jul 31, 2018

    By Lobosolo
    I’ve tried many sudoku apps, and this one is easily the best I’ve found so far. Why is it so good? 1. The hints teach you solving techniques; they don’t just give you the answer. 2. The “painting” feature allows you to quickly fill squares with fewer keystrokes, no matter whether you’re entering answers or making notes. 3. Five levels of difficulty means you can solve puzzles at exactly your level of expertise. 4. You can choose all-manual note-making and -clearing, manual note-making and auto clearing, or all auto.

  • Best sudoku out there Nov 16, 2017

    By archangel1701
    I’ve tried a lot of different sudoku games, and this one is far and away the best. No matter how you play it can do it. It’s one of the only ones that let you “paint” numbers (select a number then put it in multiple cells without having to select the number each time). There are also several different settings in terms of allowing mistakes or assisting with the number entry and cleanup, letting you tailer the game to exactly what you want. Totally worth the cost if you spend any time at all playing.

    Best sudoku game I've played. What in love the most is that I can *learn* new techniques. I can do the Hard level on my own, but generally get caught up on the expert level. The "Hints" are not just give aways. They hint, then give you the name of the technique (I sometimes look it up externally), then if you press next, they'll give you even more info. It really contributes to skill building!

    The game is fine, like the color aids and hints. Do not like the intrusive ads, can't make them go away until time out and there are at least two in a row. And really don't like that it hides the status and action bars. That bothers me. I'll likely try a different one

    Was good until they started doing double ads after and sometimes before EVERY game. I spend too much time watching ads on this app. Even after they "fixed" the ads, only a few weeks later the double ads are back. You will have 1 ad for 10 to 15 seconds, then the same product diff ad for another 10 to 15 seconds. Every single game. Its ridiculous. I'll be uninstalling and finding another. Don't waste your time. They only care about making you watch ads, and don't offer an ad free version

    Regularly glitches with the latest version. Every time I open it to play I end up having to close it and restart it because the game freezes. Thankfully, I usually don't lose progress but this gets frustrating. Even the ads will glitch and freeze often and I have to re-watch them when I reopen the app.

    Easily my favorite Sudoku app, but this new version mutes any other app playing music on your device. Absolutely unacceptable! Wait for the next version.

    The painting feature does not work. Cumbersome to use definitely not worth the purchase. Hope I can get a refund.

    Different levels of interesting Sudoku puzzles with hints and well defined rules. Enjoy solving them. The app can be improved in the following areas: 1. The screen goes blank for a few seconds while starting a new puzzle. 2. A pause button can be added to pause an ongoing game

  • Great game.... however Feb 13, 2018

    By Jetsimple
    This is a great game to learn the basic techniques. However there is a large gap between hard and expert. I can do the hard puzzles relatively easy, (usually under 5 minutes) but I go to expert and they’re borderline impossible for me. Even reading the hints, it’s still difficult to understand how to spot scenarios.

    It's a great app, the only thing I would like to have is to have option of having errors disclosed as you play a game. In your reply to me today, you had stated that if "Auto-check Errors" is enabled the app will prompt me as to how many errors i have accumulated. I have it enabled, but I have never received a prompt. I just tested it by making a error, no prompt. If you can maybe give me a support contact that I reach out o, it would be appreciated! Thanks!

  • Repetitive Jan 16, 2019

    By cynchronized
    There must be an almost infinite number of possible puzzles but only a few in this version. I'm bored with doing the same puzzles over again. Don't like the new version "flashing" at me when entering notes! Distracting! Watch out for X rated ads if children use it!

  • Grid color patterns are distracting Aug 7, 2018

    By b8ch
    Maybe it’s just me, but I find the multi-colored squares to be distracting and not helpful to playing the game. I would like the squares I fill in to be much more distinguishable from the games starting numbers. I like Sudoku and this a good version other than my comments above.

    It has some nice mechanics and options. Unfortunately, it's very difficult visually. The pencil marks are too dim, so I have to stare really hard at the screen... And then the screen dims after a very short time. That flash of darkness, brightness, then back to staring hard is just awful!

  • Good play but buggy Oct 4, 2017

    By rocktred
    I like the play dynamics, where you can set auto fill to take care of the less interesting mechanics of the game (to me at least). The reason this did not get 5 stars is that the app is buggy and crashes more than other apps.

  • Slow down and enjoy the game Mar 23, 2013

    By Nascarmom99
    I enjoy the game except...not everybody wants to compete when they play a game. I think you should have a mode that allows you to turn the timer off and just play the puzzle. It would make it more like the paper and pencil original. I don't know about you, but when I solved sudoku puzzles on paper, I didn't set a timer to see how fast I completed the puzzle. I enjoyed just working it out. The timer takes away the relaxing fun of solving the puzzles. Also, because of the score keeping, if you accidentally touch a square and it changes your previous answer, you loose points. Very frustrating.

    Hated it. Played 2 games and deleted it. Hard to see the pencil marks. Entering numbers was complicated and awkward.
