Just you, the grid, and the quiet pleasure of thinking clearly. DEEP GAMEPLAY Over 250 puzzles, each solvable, and with increasing difficulty. Hints to help you if you get stuck. Six difficulty packs run from Starter to Master. A NEW PUZZLE EVERY DAY Come back for a free daily sudoku. Keep a streak going if you like — it's a quiet counter, never a guilt trip. BEAUTIFUL ON iPAD A layout built for the big screen: the board and controls sit in one comfortable centered column, in portrait or landscape, and the grid scales beautifully to iPad. The same calm game, with more room to think.

WHAT WE BELIEVE - No ads, ever. - Privacy-first. No data monetization. - Exercising your mind through puzzles is fun. - From a studio of puzzle aficionados who believe games should be worth your time.
