The challenge in front of you
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. The example below illustrates a decision.
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. A careful first action helps you become familiar with the layout. A new-round button replaces the current round.
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. Your next round may have a different position, so inspect it before acting. Consider the next action carefully.
Where a round can go wrong
A distant tile cannot jump across other tiles. Take a moment to reassess the position before continuing. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
