What you need to achieve
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. Check the rules when you are unsure.
From the start of a round
- 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 use the controls
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.
A closer look at one example
When the gap is in the last square, only the tile above it and the tile to its left can move into it. Compare this with the rule that governs the move. Look for the relevant detail.
A common point of confusion
A distant tile cannot jump across other tiles. Read the feedback to see why an action did not have the expected result. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
