Choose a direction.
The whole picture slides toward the edge you choose. Swipe anywhere on the board, or tap an edge.
Match the edge.
Matching pixels clear when they reach it. A different color blocks the route.
Open a path.
A blocked swipe only bumps. Switch directions to move the wall away, then clear what was behind it.
Turn the rails.
Once per picture, rotate the edges one step clockwise. It costs a move, and undo gives it back.
Check the route.
Route is free. It tells you whether the picture can still be finished from here, never which way to go.
Meet the move target for 3 stars. Within 1.5x the target earns 2; finishing always earns 1. One hint per picture is free; more cap the run at 2 stars.
