Understand the aim
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.
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.
Choosing and moving on screen
Use the on-screen controls with a mouse or touch. Use the control method described here for this activity. Make sure you are interacting with the game rather than the surrounding page.
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. Focus on why the action is allowed, not only its outcome. Verify the rule before continuing.
Avoid this misunderstanding
A distant tile cannot jump across other tiles. Compare the situation with the worked example. 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.
