15 Puzzle: how a round works
Take a moment with 15 Puzzle before moving to another game. Arrange 1 to 15 in reading order with the empty square at the bottom right. Keep the game area visible while you use its controls. Identify the playing area and the controls you need. Check the relevant rule before repeating a move.
Practice with a purpose
After a move, check what changed. Decide which rule explains the new state before acting again. Refer to the controls when needed.
What you need to achieve
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. Start with a deliberate move.
Work through the instructions
- 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. A careful first action helps you become familiar with the layout. Use one clear input at a time.
See how the rules apply
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. Keep the controls nearby.
A useful caution
A distant tile cannot jump across other tiles. Read the feedback to see why an action did not have the expected result. After a move, check what changed. Decide which rule explains the new state before acting again.
