Sudoku

How to play

Fill the grid so every row, every column and every 3 by 3 box contains the numbers 1 to 9 once. The puzzle always has exactly one answer, so you can solve it with logic and never need to guess. Pick a square and type a number (or tap a number below the grid). Switch on Notes to jot small pencil marks. The host chooses the way to play and presses Start. Solo is you against the puzzle. In a Race everyone has the same puzzle on their own grid and the first to finish wins. In Co-op everyone fills in one shared grid together. Check shows which numbers are wrong, and you get three hints. Pick a level from Easy to Expert, play the puzzle of the day, or type a puzzle code to replay one a friend has shared.
