Tap a tile in the same row or column as the empty space, and it slides over, along with any tiles in between. You can also use the arrow keys. Tiles in their correct place change color. Close anytime and choose the same size to continue.

How to play the sliding puzzle

  • The frame holds numbered tiles and one empty space: tiles 1 to 15 on the 4×4 board, 1 to 8 on 3×3 and 1 to 24 on 5×5.
  • A tile next to the empty space (above, below, left or right) can slide into it. Tap a tile in the same row or column as the empty space and the tiles in between slide along with it.
  • Put the tiles in order, 1, 2, 3… left to right and top to bottom, with the empty space in the bottom right corner, to solve the puzzle.
  • Moves are counted by tiles slid. Sliding three tiles at once counts as three moves.
  • Exactly half of all tile arrangements can never be solved. This site only gives you puzzles that can be solved.

Tips for solving it faster

Solve the top row first, then the second row. Once a row is done, avoid breaking it up.

The last two tiles of a row are the tricky part. Line them up vertically first, then rotate them into place around the corner.

When only two rows are left, solve them column by column from the left, placing the top and bottom tiles as a pair.

Start with 3×3, then move on to 4×4 and 5×5. Bigger boards work the same way: top rows first, then the left columns.
