Fun Free Sudoku! No more lugging around Sudoku books in my purse! I enjoy playing whenever I want for free! Fun games. I enjoyed playing very much.

Amazing sudoku app. I'm making this review way after they ask me to (in case they sneak sth in after) and it's great. Only ad is after a game. Only criticisms I have is the app does not tell you how many mistakes you've made mid-game, and it does not pause your time when your screen is off. This app is now my go-to for Sudoku.

Best sudoku app ive found so far. And It's way challenging than most killer sudoku out there. I just completed my first Invictus level with no mistakes and without using hints!

Latest update has bugs. The pencil marks of killer sudoku overlaps the cage value, which makes it unreadable. Please update. Also, turn the pencil brown in pencil mode.

The latest update ruined the experience for me. The color scheme is awful, game does not keep my personal bests, only from this day. Big downgrade.
★☆☆☆☆Greg Hobbs· Nov 20, 2024
It takes longer to exit out of adds now compared to when I first started playing. Why is that. This is the reason I will uninstall your game. It is frustrating. Please EXPLAIN! And don't tell me they're no longer, because you know they are!
