How to play

  1. Tap a square, then tap a number to place it. On a keyboard, use the arrow keys and the number keys.
  2. Switch Notes on to pencil in small candidate numbers instead.
  3. Numbers that clash with another in the same row, column or box turn red.
  4. Use Check to see whether your numbers are right, or Hint if you are stuck.

Tips

  • Look for a number that can only go in one square of a box.
  • Fill in the rows and columns that already have the most numbers first.
  • Use notes to track candidates when two or three numbers are possible.
