Take a quiet moment to reason through a number puzzle. Fill each row, column, and box without repeating a value, and enjoy the satisfaction of a fully valid solution.

Choose a compact 6×6 board or a classic 9×9 board. Six chapters offer twenty puzzles each, with challenge increasing through fewer starting clues and more involved candidate relationships. Every puzzle has a unique solution.

Learn by doing with a short, interactive 4×4 tutorial. During a game, enter answers or keep candidate notes in an empty square. Check the grid to mark conflicts without revealing the solution, undo or redo a move, and use up to three hints that explain a single-candidate deduction.

Play at your own pace with no countdown. Your unfinished board, notes, timer, and undo history are saved on your device. A date-based daily challenge is selected from the included puzzle set and works offline.

Review completion time, undo and hint use, chapter progress, daily challenge history, and fastest personal times. Choose a light, dark, or device-based theme, and adjust sound, motion, conflict marks, and candidate assistance to suit your play.

Puzzles, preferences, and records stay in local app storage. No account or network connection is needed to play.
