Lockstep: Bead Puzzle is a calm game about moving everything at once. Swipe, and every bead on the board takes one step in that direction. A bead stops when a wall, the edge or another bead is in the way, and that's how you pull them apart. Get each bead onto its matching ring. • Hand-made cards from Beginner to Expert, each checked by a solver. Par is the fewest swipes possible; match it for three stars. • A Daily card, the same for everyone, with a streak to keep. Send it to a friend: they can play it straight from the link, even without the app. • Endless run: puzzles get harder, and swipes over par spend your spares. • Shuffle: a fresh puzzle at any difficulty, whenever you want one. • Arrows, holes, and a secret deck for those who clear every Expert card. • Hints that point the way without giving it away. • Plays on iPhone, iPad, Mac, Apple TV and Apple Watch, with progress synced through iCloud. • Game Center leaderboards and achievements. Free to play: the Daily card, the Beginner and Intermediate cards, and Beginner Shuffle. Lockstep Complete, a one-time purchase, unlocks Advanced and Expert cards, the secret deck, Endless and every Shuffle level, on all your devices and for your family.
