Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Make the next step deliberately.
The challenge in front of you
Arrange 1 to 15 in reading order with the empty square at the bottom right. Use the instructions to see which actions move you towards it. Follow this game’s rules rather than another version’s.
The order of play
- Select a tile directly beside the empty square.
- The tile slides into the gap; diagonal moves are not allowed.
- Use Undo to step back one move.
- Finish the ordered board, or choose New puzzle.
Controls
Use the on-screen controls with a mouse or touch. Keep the playing area visible while using these controls. Return to the rules if the result is unexpected.
A closer look at one example
When the gap is in the last square, only the tile above it and the tile to its left can move into it. Compare this with the rule that governs the move. Take a moment to compare.
Watch out for this
A distant tile cannot jump across other tiles. A different version of the game may use a different rule. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
