Make room.Then make your move.
Move one piece, and another piece's path changes. Look at how the pieces fit together and decide where to start.
Start with one puzzle. No download needed.
A stop can be a useful move.
Tap a piece. It moves along its arrow until it meets another piece. Even when it cannot leave the board yet, the space it creates can help your next move.
Find a piece that can move.
Follow its arrow and look for whatever is blocking its path.
Work on another piece.
Leave the stopped piece in place. A move elsewhere may open a new path.
Look again at the pieces left behind.
Free every piece to clear the puzzle. If no pieces can move, undo one step and try another idea.
