This used to be my second favorite sudoku app, due to satisfying difficulty but hated the user interface. Then one day I thought I found a bug in the puzzle emailed the dev and he emailed me right back, so I told him my suggestion about the interface. Today I jumped on for the first time in a few weeks to learn he got the change deployed and the experience is even better than I expected, love it!!

This is a good sudoku game. I love all the different challenges it gives (classic and odd/even are my favorites, even irregular is fun). My only gripe about this game is that you're only given a three free volumes and the rest of them are pay-to-play. Not expensive though. If you're willing to pay a couple dollars for each additional volume (from 50-100 puzzles each), then I'd check this out. Moto G Stylus 5G.

Sudoku is a fun puzzle game when you are bored and they added a twist by making different sized puzzles. A big plus is that this app doesn't need internet, so you can play it as long as you have charge. Different sudoku apps I have used before have had some weird controls that are touchy and can get annoying pretty fast. This app has better controls that simpler for playing, which is nice for a mobile game.
