About this game
Sudoku is the classic 9×9 number puzzle — free, offline and endlessly satisfying. Fill the grid so every row, every column and every 3×3 box contains the numbers 1–9 with no repeats. Tap a cell, pick a number, and use pure logic to solve. Simple to learn, a joy to master.
Choose your challenge across four difficulty tiers — Easy, Medium, Hard and Expert — or take on a fresh Daily Sudoku every day and build a solving streak on the calendar. Every puzzle is generated with a single guaranteed solution, so you never run out. Pencil notes, conflict highlighting and a hint system help when you're stuck, while a relaxed Zen mode and a tense limited-mistakes mode let you play your way. Track your best times and streaks on the stats screen.
