How to play

Every swipe moves every bead one step in that direction at the same time. A bead stops if a wall, the edge or another bead is in the way, which is how you pull them out of sync. Land each bead on the ring of the same shape and colour. Arrows give a bead one extra push after each swipe; a bead that slides into a hole is lost. Par is the fewest swipes possible, found by a solver: match it for three stars.
