How to Play Slide Puzzle

Slide Puzzle is the classic sliding tile game: a 4x4 grid holds fifteen numbered tiles and one empty square. Slide the tiles around the empty space until the numbers run from 1 to 15 in order. There is no timer and no way to lose, which is exactly why it works as a wind-down game — you can pick it up for two minutes or twenty, and the only thing that matters is the next move. It runs in your browser with no download and no sign-up.

  • Click or tap any tile directly next to the empty square to slide it into that space.
  • Move one tile at a time, and only into the gap.
  • Arrange the tiles from 1 through 15, left to right and top to bottom.
  • Use Shuffle to start a fresh puzzle whenever you like.

Tips and Strategy

Start With the Top Row

Solve tiles 1 to 4 first and then leave that row alone. Trying to fix the whole board at once makes it harder to see your next move.

Work Row by Row

After the first row, finish the second, then the third. Keep completed rows intact while you work below them.

Keep the Empty Square Moving

Plan two or three moves ahead and guide the gap around the tiles you still need to move.
