15 Puzzle: instructions and practice
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. Look at what changes after your first action. Make your first input carefully and watch the result. Check the relevant rule before repeating a move.
Try a more deliberate round
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. Refer to the controls when needed.
Understand the aim
Arrange 1 to 15 in reading order with the empty square at the bottom right. Read that aim before choosing your first action. Take a moment to understand the current position.
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.
How your actions work
Use the on-screen controls with a mouse or touch. On a smaller screen, keep the active part of the board within view. Return to the rules if the result is unexpected.
An example before you play
When the gap is in the last square, only the tile above it and the tile to its left can move into it. Focus on why the action is allowed, not only its outcome. Keep the game’s format in mind.
Where a round can go wrong
A distant tile cannot jump across other tiles. Check the rule before repeating the action. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
