Sudoku
The classic 9 × 9 logic puzzle, always with exactly one solution. Pencil in candidates, lean on smart highlighting, and pick from four difficulties. Every puzzle is generated on your device from a seed, so you can send a friend the exact same grid.
How to play
- 1
Fill every empty cell
Place a digit from 1 to 9 so no row, column or 3 × 3 box ever repeats one.
- 2
Pencil in candidates
Turn on Notes to jot down what a cell could be. Placing a digit tidies the notes around it.
- 3
Follow the highlights
Selecting a cell lights up its row, column and box. Tap digits in the color chart to light up every cell that holds them.
- 4
Solve it cleanly
Every puzzle has exactly one solution. A hint walks you through the next cell step by step; with strikes on, three mistakes end the round.
