How to play 15 Puzzle

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. Use the example below to understand a decision. Check the rule that explains your first action. Look at what changes after your first action.

A useful comparison

Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Refer to the controls when needed.

Your goal

Arrange 1 to 15 in reading order with the empty square at the bottom right. Read that aim before choosing your first action. The example below illustrates a decision.

Step by step

1. Select a tile directly beside the empty square.
2. The tile slides into the gap; diagonal moves are not allowed.
3. Use Undo to step back one move.
4. Finish the ordered board, or choose New puzzle.

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.

A useful 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. Verify the rule before continuing.

Watch out for this

A distant tile cannot jump across other tiles. Read the feedback to see why an action did not have the expected result. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
