Sudoku: Classic Puzzle Game

Sudoku is the classic number puzzle game, reimagined with a clean, distraction-free design built for daily brain training. Whether you're new to Sudoku or a longtime solver, this app gives you everything you need to relax, focus, and sharpen your logic — anytime, anywhere, even offline. Play a fresh puzzle every time with four difficulty levels: Easy, Medium, Hard, and Expert. Each puzzle is uniquely generated, so no two games are ever the same, and every difficulty is tuned to give you a fair, satisfying challenge whether you're just starting out or chasing a personal best time. Not sure where to place a number? Use Notes mode to pencil in candidates the way you would on paper, or tap Hint when you're stuck. Auto-check mistakes instantly flags wrong entries so you can learn as you play, and Check mode lets you verify your progress at a glance. Undo lets you correct a slip without losing your streak.
