Seventy-two levels where the task is simple to describe and not simple to accomplish: all the Swift Blocks on the board must reach their target positions at exactly the same time. Swirls and static elements complicate the routing, sometimes helping and sometimes blocking. Hints reveal the first half of the optimal solution when a level goes cold; skipping is always available for levels best revisited later. Difficulty climbs gradually from beginner to expert, and the skills it builds are the ones you use to approach the next harder puzzle.
