15 Puzzle: how a round works
Try 15 Puzzle at your own pace and keep its objective in view. Arrange 1 to 15 in reading order with the empty square at the bottom right. Use the example below to understand a decision. Identify the playing area and the controls you need. Keep the game area visible while you use its controls.
Practice beyond the first move
Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart. Use the example to check your reasoning.
The goal to keep in mind
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. The example below illustrates a decision.
Step by step
- 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 to use the controls
Use the on-screen controls with a mouse or touch. Keep the playing area visible while using these controls. Contact us with the game and device if a control does not respond.
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. Use the example as a guide rather than a substitute for reading your board. Consider the next action carefully.
One detail worth checking
A distant tile cannot jump across other tiles. Check the rule before repeating the action. After a move, check what changed. Decide which rule explains the new state before acting again.
