I used to play sudoku years ago and recently saw a free version with ads. The ads were a huge distraction. I downloaded this version and it's great. Even the easy ones are challenging. great way to clear your head and relax. Have fun! update: I've been playing for 6 weeks or so. Still playing easy ones but really improving my time. fun. challenging. relaxing.

Almost perfect game, well worth 3.99. Classic mode is better than buying book after book. I don't really review things, but this is legit. A message to developers tho... the ultimate mode sucks, easy is not easy, completely different controls and layout. It feels like u shoved a completely different game into it just for an extra option to play. For a paid game I really hope you keep working to make it better.

This is a straightforward game of sudoku, which I enjoy playing each day. Has 250 puzzles per level plus 500 extra puzzles for another five levels. Tracks how long it takes you to complete a puzzle so you can work to improve your time. No ads to sit through (at least so far) and you can restart (clear) your puzzle if you realize you messed up somewhere along the line. I enjoy the challenge and picking up patterns/techniques at each level.
