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. Keep the instructions close while learning this activity. Check the relevant rule before repeating a move.
A careful first round
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Make the next step deliberately.
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. Check the rules when you are unsure.
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. Read a button’s label before selecting it. Return to the rules if the result is unexpected.
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. Keep the game’s format in mind.
Watch out for this
A distant tile cannot jump across other tiles. Compare the situation with the worked example. After a move, check what changed. Decide which rule explains the new state before acting again.
