How to play Slide Fifteen

The board is full of numbered tiles and one empty gap. Your goal is to put the numbers in order: 1, 2, 3 and so on. The gap should end up in the bottom-right corner.

  1. Tap a tile that is in the same row or column as the gap. That tile, and any tiles between it and the gap, slide over.
  2. You can also swipe on the board, or use the arrow keys.
  3. A tile turns green when it is in its right spot.
  4. When every tile is green, you win.
