EASY TO LEARN, ROOM TO IMPROVE Drag blocks onto the 8x8 grid and complete rows or columns to clear space. Plan your next move, build combos, and use the Hold slot to save a piece for later. A playable introduction helps you get started. CHALLENGE A FRIEND Create an online room and share its code. Both players receive the same piece sequence at Normal difficulty. • Classic: each player completes their run, then scores decide the winner. • Rush: race for the highest score on a shared 60-second timer. • Send reactions and messages, compare scores live, and agree to a rematch. • Saved match progress helps you return after a brief interruption. Online 1v1 requires an internet connection and two devices running the latest version. Nearby discovery helps you find a room; the match still uses the internet. Leaving a match or a prolonged disconnection counts as a loss. FIND YOUR SOLO RHYTHM • Classic: make space and work toward a new personal best. • Daily Challenge: play the day's seeded challenge and earn personal medals. • Rush: make quick decisions against the clock. • Survival: manage rising blocks and keep your board open. • Mission: work toward changing objectives. • Adventure: progress through a map of puzzle levels.
