About this app
Read full description
Sudoku, and nothing else. No ads, no account, no internet. Just the puzzle. I made this because every other Sudoku app felt loud — banners, pop-ups, daily-reward nags. This one stays quiet. Every puzzle is generated fresh and checked to have exactly one solution, so you never run out. Ways to play: Journey — start easy and climb level by level. Adaptive — it learns how you play and picks boards that fit. Choose difficulty — Easy through Expert, and a Master tier beyond it. Notes, undo, erase. Stuck on a cell? One tap fills the next correct number. Wrong-entry checking is there if you want it, off by default. The records page keeps your streak, solved days, and best times. Everything runs on your phone. Nothing is collected, nothing is sent anywhere. Light and dark themes, with optional sound and haptics. English and Korean.
