The challenge in front of you
Arrange 1 to 15 in reading order with the empty square at the bottom right. Keep that objective in view throughout the round. Take a moment to understand the current position.
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.
Controls
Use the on-screen controls with a mouse or touch. A careful first action helps you become familiar with the layout. Use one clear input at a time.
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. Check the stated objective.
An important reminder
A distant tile cannot jump across other tiles. A different version of the game may use a different rule. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
