The essentials of playing 15 Puzzle
Bring your attention to one round of 15 Puzzle. Arrange 1 to 15 in reading order with the empty square at the bottom right. Look at what changes after your first action. Identify the playing area and the controls you need. Check the relevant rule before repeating a move.
Practice with a purpose
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Use the example to check your reasoning.
Aim for this result
Arrange 1 to 15 in reading order with the empty square at the bottom right. Keep that objective in view throughout the round. Start with a deliberate move.
Work through the instructions
- 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.
Choosing and moving on screen
Use the on-screen controls with a mouse or touch. A careful first action helps you become familiar with the layout. Look at the feedback after the action.
Put the rules into context
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.
Avoid this misunderstanding
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.
