An idea for your next attempt
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Refer to the controls when needed.
The purpose of your moves
Arrange 1 to 15 in reading order with the empty square at the bottom right. Use the instructions to see which actions move you towards it. Notice how the game responds to your input.
Follow these playing steps
- 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.
The controls to know
Use the on-screen controls with a mouse or touch. Use the control method described here for this activity. Use one clear input at a time.
Learn from a sample situation
When the gap is in the last square, only the tile above it and the tile to its left can move into it. Use the example as a guide rather than a substitute for reading your board. Take a moment to compare.
One detail worth checking
A distant tile cannot jump across other tiles. Take a moment to reassess the position before continuing. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
