15 Puzzle: what to know before playing
Choose a round of 15 Puzzle and settle into its rules. Arrange 1 to 15 in reading order with the empty square at the bottom right. Keep the game area visible while you use its controls. Identify the playing area and the controls you need. Use the example below to understand a decision.
Practice beyond the first move
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Keep the objective visible.
Your objective
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. Keep the controls in easy reach.
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. On a smaller screen, keep the active part of the board within view. 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. Apply the same reasoning to the position in your own round. Verify the rule before continuing.
Pay attention to this rule
A distant tile cannot jump across other tiles. Take a moment to reassess the position before continuing. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
