THE NUMBER PUZZLE

Classic Sudoku logic sits at the heart of THE NUMBER PUZZLE, placing you in front of a 9×9 grid that demands careful thought rather than guesswork. Every row, column, and 3×3 box must contain the digits 1 through 9 — no repeats, no shortcuts.

Four difficulty settings shape how demanding each session gets. Lighter grids leave more numbers pre-filled, while harder configurations strip the board down to a bare minimum, forcing you to reason through chains of possibilities before committing a single digit.

A built-in hint system and undo function give you room to experiment without losing progress. The timer runs quietly in the background — useful if you want to measure improvement over time, easy to ignore if you'd rather just think at your own pace.
