Understand the basics of 15 Puzzle
Open 15 Puzzle, check the instructions and begin a round. Arrange 1 to 15 in reading order with the empty square at the bottom right. Look at what changes after your first action. Use the opening round to become familiar with the layout. Choose a clear next step rather than rushing through the instructions.
Take a closer look while playing
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Keep the objective visible.
Aim for this result
Arrange 1 to 15 in reading order with the empty square at the bottom right. Read that aim before choosing your first action. Return to the instructions when a step is unclear.
The steps to play
- 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. Use the visible help when you are unsure of the next input.
Learn from a sample situation
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. Read the matching step again.
Avoid this misunderstanding
A distant tile cannot jump across other tiles. Read the feedback to see why an action did not have the expected result. After a move, check what changed. Decide which rule explains the new state before acting again.
