An introduction to playing 15 Puzzle
Start 15 Puzzle by looking at the playing area and its controls. Arrange 1 to 15 in reading order with the empty square at the bottom right. Check the relevant rule before repeating a move. Identify the playing area and the controls you need. Keep the game area visible while you use its controls.
Practice with a purpose
Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart. Use the example to check your reasoning.
What counts as success
Arrange 1 to 15 in reading order with the empty square at the bottom right. Keep that objective in view throughout the round. The example below illustrates a decision.
A walkthrough of the rules
- 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.
Making selections and moves
Use the on-screen controls with a mouse or touch. Use the control method described here for this activity. Read the example below alongside these instructions.
An example before you play
When the gap is in the last square, only the tile above it and the tile to its left can move into it. Your next round may have a different position, so inspect it before acting. Notice the change in the playing area.
A common point of confusion
A distant tile cannot jump across other tiles. Check the rule before repeating the action. 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.
