15 Puzzle: how a round works
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. Use the example below to understand a decision. Use the opening round to become familiar with the layout. Look at what changes after your first action.
A small practice goal
Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules. Use the example to check your reasoning.
The objective of a round
Arrange 1 to 15 in reading order with the empty square at the bottom right. The feedback beside the game helps you follow the round. Notice how the game responds to your input.
The playing sequence
- 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.
Using the playing area
Use the on-screen controls with a mouse or touch. On a smaller screen, keep the active part of the board within view. Check any mode label before starting.
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. Choose a deliberate next step.
Watch out for this
A distant tile cannot jump across other tiles. A different version of the game may use a different rule. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
