Understand the basics of 15 Puzzle

Identify the playing area and the controls you need. Choose a clear next step rather than rushing through the instructions.
A small practice goal
Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round. Refer to the controls when needed.
Your objective
Arrange 1 to 15 in reading order with the empty square at the bottom right. Keep that objective in view throughout the round. Follow this game’s rules rather than another version’s.
The order of 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.
How to interact with the game
Use the on-screen controls with a mouse or touch. Keep the playing area visible while using these controls. Make sure you are interacting with the game rather than the surrounding page.
See how the rules apply
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. Check the stated objective.
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.
