How to Play Sudoku Master

Fill the 9×9 grid. Every row, column, and 3×3 square needs the numbers 1 to 9. No repeats. That's the law. Your mission? Scan the board. Find the logical gaps. Lock in digits. Solve without mistakes.

Core Mechanic: The Sudoku Loop

Tap a cell. Pick a number from the keypad. Watch the highlights. Rows, columns, and squares light up to show conflicts. Use Notes to pencil in candidates. Cross out bad options as you narrow down solutions. Made a mistake? Hit Erase. Wrong digit entirely? Tap Undo. You get 3 strikes before game over. No room for sloppy clicks.

Progression: Beginner to Master

Start with Beginner puzzles. Easy fills. Plenty of starting digits. Clear the grid. Unlock Easy. Then Medium. Hard. Finally, Expert. Master difficulty is locked until you prove yourself. Each tier removes more numbers and demands sharper logic. Stats track your solve times, mistake rates, and streaks. Daily challenges reset every 24 hours. Complete them for bonus achievements.

Pro Strategy: Hints and Notes

Stuck? Use a Hint. The game auto-fills one correct cell. You've got 99+ hints stocked (watch ads or buy more in the shop). Smart play? Save hints for the brutal endgame when you're one digit away from victory. Always toggle Notes mode early. Fill cells with 2-3 candidates. Eliminate fast. Solve faster. Ignore the temptation to guess. Wrong digits kill your streak and burn a mistake.
