How to play Sliding Puzzle

A sliding puzzle is a picture cut into squares, with one empty spot. Slide the squares around to fix the picture!

  1. Look at the picture so you know what it should look like.
  2. Find the empty spot. Only squares next to it can move.
  3. Tap a square next to the empty spot to slide it over.
  4. Keep sliding squares to move them where they belong.
  5. Start with the top row. Put those squares in place first!
  6. When every square is in the right spot, the picture is complete!
