Sudoku+ on iPhone, partway through a Hard puzzle. The selected square’s row, column and box are shaded, and four squares hold pencilled notes.

Four ways to play

Same nine digits. Four different puzzles.

Each one has its own daily puzzle, its own streak and a free pack of 50 to work through.

  • A Classic board in the app: a 9 by 9 grid with its starting digits on shaded squares.

    Classic

    The 9×9 original. Fill every row, column and 3×3 box with the digits 1 to 9.

  • A Killer board in the app: an empty 9 by 9 grid divided into dashed cages, each with a small sum in its corner.

    Killer

    No starting digits. Each dashed cage shows the sum of its cells, and a digit can’t repeat inside a cage.

  • A Butterfly board in the app: a 12 by 12 grid with starting digits scattered across it.

    Butterfly

    Four overlapping 9×9 grids share one 12×12 board. Each of the four takes 1 to 9 once.

  • A Mini board in the app: a 6 by 6 grid with 2 by 3 boxes.

    Mini

    A 6×6 grid with 2×3 boxes and the digits 1 to 6. Made for a short break.
