How to Play Sudoku
1. Fill the Grid
Every row, column, and box must contain each number exactly once.
2. Tap & Type
Tap a cell to select it, then use the number buttons to fill it in. Tap the eraser to clear a cell.
3. Watch for Conflicts
Numbers that clash with their row, column, or box turn red.
4. Complete the Puzzle
Fill every cell with no conflicts and the puzzle solves automatically!
5. Keep Your Streak
Solve puzzles in a row to build your streak. Puzzles get harder as your streak grows. Giving up resets your streak!
