Master Sudoku

Master Sudoku is the classic number-placement puzzle on a 9x9 grid. The rule is simple: every row, every column and every 3x3 box must contain the numbers 1 to 9 exactly once. No math is needed, only careful logic and a bit of patience.

The game offers four difficulty levels: Easy, Medium, Hard and Expert. Beginners can start with Easy to learn how to spot the obvious placements, while experienced players can move up to Expert for puzzles that demand deeper deduction. It is a quiet, focused game that is easy to pick up for a few minutes or a long session.
