How to Play

Fill the 9×9 grid so every row, column, and 3×3 box contains the digits 1 to 9 without repeats.

Tap any cell, then tap a number 1–9 (or type it on your keyboard).
Toggle Notes (N) to jot down pencil-mark candidates inside empty cells. Placing a number automatically clears matching notes in the same row, column, and box.
Duplicate numbers in a row, column, or box highlight in red so you can spot conflicts right away.
Use Hint if you get stuck — clean solves with 0 hints earn a ★ on the leaderboard.

Keyboard: 1–9 place digit · N toggle notes · Backspace erase · U undo · ←↑→↓ move

Daily releases a fresh Easy, Medium, and Hard puzzle every midnight. Use the calendar button (📅) to play any past day you missed.
