How to play 15 Puzzle
15 Puzzle gives you a focused activity to play in your browser. Arrange 1 to 15 in reading order with the empty square at the bottom right. Choose a clear next step rather than rushing through the instructions. Choose a comfortable screen position before beginning. Check the relevant rule before repeating a move.
A useful comparison
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Make the next step deliberately.
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. 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. A careful first action helps you become familiar with the layout. Use the visible help when you are unsure of the next input.
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. Apply the same reasoning to the position in your own round. Choose a deliberate next step.
Watch out for this
A distant tile cannot jump across other tiles. A different version of the game may use a different rule. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
