How to Play

If you're new to Sudoku, don't worry — the rules are very simple: Goal of the game: fill the entire game board (a 9×9 grid) with numbers from 1 to 9 so that in each row, each column, and each 3×3 block, every number appears only once. Controls: Tap on an empty cell — it will be highlighted. Then tap on one of the numbers at the bottom of the screen to enter it into the cell. If you make a mistake, tap on the cell with the wrong number, then tap the "Erase" button (or choose a different number to replace it). Hints: If you're stuck, use a hint. Hints can be bought with in-game coins, which you earn by completing levels, or obtained by watching an ad. The "Check Errors" function is also available: it highlights incorrect numbers without solving the puzzle for you. Start with the first level and gradually increase the difficulty. Good luck!
