Try a more deliberate round
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Make the next step deliberately.
What you are aiming for
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. Keep the controls in easy reach.
Making your moves
- 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.
Getting comfortable with the controls
Use the on-screen controls with a mouse or touch. Read a button’s label before selecting it. Make sure you are interacting with the game rather than the surrounding page.
See how the rules apply
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. Keep the game’s format in mind.
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.
