15 Puzzle: a guide for your next round
Use a short break to learn the rhythm of 15 Puzzle. Arrange 1 to 15 in reading order with the empty square at the bottom right. Look at what changes after your first action. Identify the playing area and the controls you need. Check the relevant rule before repeating a move.
One thing to notice as you play
After a move, check what changed. Decide which rule explains the new state before acting again. Refer to the controls when needed.
The objective of a round
Arrange 1 to 15 in reading order with the empty square at the bottom right. The feedback beside the game helps you follow the round. Check the rules when you are unsure.
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.
Controls
Use the on-screen controls with a mouse or touch. On a smaller screen, keep the active part of the board within view. Check any mode label before starting.
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. Apply the same reasoning to the position in your own round. Notice the change in the playing area.
A useful caution
A distant tile cannot jump across other tiles. Compare the situation with the worked example. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
