How to play

• Only a tile touching the empty square can move, and it moves into it.
• Put the tiles back in order, with the gap at the bottom right.
• Clicking a tile further along a row or column slides the whole row at once.
• Picture mode replaces the numbers with a generated pattern.
• Your score is the number of moves, so fewer is better.

Tips

• Solve the top row and the left column first, then never touch them again.
• The last two tiles of a row are placed together, not one after the other.
• On the final three-by-three block, work in circles rather than straight lines.
• If a row will not close, rotate its last two tiles through the row below.
