Two orbs. One connection. Every gate asks a question: can you rotate in time? Space-Duo is a fast, neon arcade game about two orbs flying through space together. Tap to rotate your duo so it fits through the gap in each gate. Simple to learn, hard to master โ€” and every run is a fresh chance to beat your best. THREE WAYS TO PLAY CLASSIC Fly through four levels that get faster and change shape as you go. From Level 3, gates slide sideways โ€” swipe to line up and rotate to pass. Charge a shield that saves you from one mistake, grab golden crystals, and earn bonus points for close calls. SPEED DEMON Three lives, nonstop speed. Chain perfect passes to build a Rush streak and push your score higher before your lives run out. POLARITY Your orbs become a blue circle and a pink diamond, and each gate shows exactly where each one must go. Tap the left side to rotate left, the right side to rotate right. Match them perfectly to grow your SYNC streak. DAILY CHALLENGE A new challenge every day with its own rules and target score. MAKE IT YOURS Visit the store to unlock new orbs, trails, connection beams and animated space backgrounds. Earn stardust in every run, or buy the designs you love.
