How to play 15 Puzzle
Read the aim of 15 Puzzle, then make your first move. Arrange 1 to 15 in reading order with the empty square at the bottom right. Look at what changes after your first action. Choose a comfortable screen position before beginning. Use the example below to understand a decision.
Keep the aim in sight
Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules. Refer to the controls when needed.
Your goal
Arrange 1 to 15 in reading order with the empty square at the bottom right. An attractive position is not enough unless the goal is met. Try to explain the aim in your own words.
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.
Controls
Use the on-screen controls with a mouse or touch. Use the control method described here for this activity. Look at the feedback after the action.
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. Compare this with the rule that governs the move. 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. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
