THE NUMBER PUZZLE

THE NUMBER PUZZLE presents the familiar Sudoku format on a 9 by 9 grid. Fill every row, column, and three by three box with numbers from 1 to 9, using logic to place each value without repetition.

Several difficulty choices let you select a suitable kind of challenge, from Easy through Expert. A timer adds a speed element, while hints and undo provide support when a deduction becomes difficult. The result is a focused number game built around careful reasoning rather than quick reactions.
