How to play 6×6 Sudoku

Start playing ↗

  1. Find a row with few gaps

    If a row already has five numbers, the missing one is easy to find. Count from 1 to 6 and see which digit is not there.

  2. Check the box too

    Before writing a number, look at its column and its 2×3 box. A digit can only appear once in each.

  3. Use the helpers

    Tap a number to highlight it everywhere on the grid. The small counter on each button shows how many of that digit are still missing.

  4. Move up when ready

    Easy puzzles have 20 clues, Medium 15, and Hard about 10. When Hard feels easy, try a 9×9 Easy Sudoku.
