Comments on Clean Sudoku: Puzzle & Solver for Android

★★★★☆ Maria Pili Potter · Aug 17, 2024
Really good game. No ads whatsoever. I gave it a four because for some reason it's not turning wrongly placed numbers red. It was fine until recently. It will show you've made a mistake but won't change number color. Please fix, devs
★★★★★ Closet Furry · Sep 30, 2025
Best sudoku app by a country mile!! No intrusive ads, no fluff, just good old-fashioned sudoku to keep your mind sharp. Cheers, devs!! edit-does seem to be an issue with the puzzle not ending when finished; clicking the hint button appears to jog the game back to working order!
★★★★★ Anthony Castillo (Tony) · Aug 29, 2025
Everything you want in a mobile game. No advertisements, no premium edition paywalls, just good, clean Sudoku. Fishtail Apps, I salute you. 🫡
★★★★★ J B · Mar 28, 2026
Withour doubt the best Sudoku app I've ever played. Love the features. Especially the way it intuitively highlights the numbers and rows you are working on. The difficulty setting deserving a special mention with four setting rather than the usual three. Only one minor complaint. I wish the notes were easier to see as I rely on them to complete the more difficult grids. If they were a tiny fraction bigger. Maybe slightly thicker and definitely a bit darker than this app would be perfect.
★☆☆☆☆ Sandy Cole · Jul 29, 2026
Had this app for a few years. Absolutely loved it. Until you updated it yesterday. I can see the board, but not the number board. Can't play without a number board to place numbers on the game.
★☆☆☆☆ Nikhil Yadav · Oct 10, 2024
I put notes for sudoku and went on home screen when came back and resumed game all notes were lost Wasted my 1 hour of solving.
★★☆☆☆ Guinevere Larsen · Apr 19, 2026
Really disappointed with the newest update. I used to like this app because it had no ads, in spite of all the issues it had. Now, when you use a hint, it plays an ad. time to uninstall the app
