Just you and the numbers, whether it's a short break or the last few minutes before bed. ■ 17,000+ puzzles, all offline ・Standard (9×9) — 4,000 puzzles ・Diagonal (X-Sudoku) — 4,000 puzzles ・Jigsaw — 4,000 puzzles ・Killer — 4,000 puzzles ・Various sizes (4×4 / 6×6 / 16×16) — 1,350 puzzles Four difficulty levels: Easy, Medium, Hard and Expert. Start with a 4×4 grid, or go all the way to 16×16 Expert. ■ Five board types ・Standard: no repeated digits in any row, column or block ・Diagonal: the two diagonals must also be free of repeats ・Jigsaw: irregular, color-coded blocks instead of 3×3 boxes ・Killer: the digits inside each dotted-line cage must add up to the small number in its corner — Hard and Expert puzzles start with no given numbers, so the sums are all you have ・Various sizes: the same rules on 4×4, 6×6 and 16×16 grids ■ Assists that keep you in the flow ・Memo (pencil mark) mode for candidate numbers ・Auto-remove memos when a number is confirmed ・Hints — up to 3 per puzzle; auto-fill the cell or just highlight it ・Unlimited Undo / Redo ・Remaining-number display: finished digits gray out ・Auto-complete for the last remaining digit ・Cage combinations for Killer — see which digit sets add up to the selected cage (can be turned off) ・Optional mistake highlighting — turn it off to solve unaided ■ Two input modes, switchable anytime ・Cell first: tap a cell, then tap a number ・Number first: hold a number and tap cell after cell In both modes the app pre-selects the key or cell you're most likely to need next, so you keep moving. ■ Stop anytime, resume anytime Your board is saved automatically on every move.
