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. Follow this game’s rules rather than another version’s.
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.
Keyboard and screen controls
Use the on-screen controls with a mouse or touch. A careful first action helps you become familiar with the layout. Avoid pressing the same control repeatedly while a move is being processed.
See the idea in action
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. Verify the rule before continuing.
Notice this detail
A distant tile cannot jump across other tiles. Take a moment to reassess the position before continuing. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
