Kazuwa Sudoku is the cleanest way to play Sudoku on your iPhone. Every time you open the app, a freshly generated puzzle is waiting. No menus to dig through, no accounts to create, no ads to dismiss — just a crisp 9×9 grid ready for your next move. Choose your challenge. Easy warms you up; Expert will test everything you've got. A built-in timer tracks your solve time, and your personal stats — best time and average per difficulty — are saved automatically so you can watch yourself improve. Tap any empty cell and choose a number from the pad. Not ready to commit? Switch to Pencil Mode and leave candidate notes right on the board. Made a mistake? Undo (and redo) as many times as you need. Toggle auto-check on to catch conflicts the instant they appear, or turn it off for a tougher test of your logic. When you complete a row, column, or box, the whole group lights up with a satisfying animation — and a soft, musical ding marks every milestone on the way to the solution.
