When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Refer to the controls when needed.
The purpose of your moves
Arrange 1 to 15 in reading order with the empty square at the bottom right. An attractive position is not enough unless the goal is met. Try to explain the aim in your own words.
The steps to 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.
Keyboard and screen controls
Use the on-screen controls with a mouse or touch. On a smaller screen, keep the active part of the board within view. Use one clear input at a time.
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. Your next round may have a different position, so inspect it before acting. Look for the relevant detail.
Avoid this misunderstanding
A distant tile cannot jump across other tiles. A different version of the game may use a different rule. After a move, check what changed. Decide which rule explains the new state before acting again.
