About this game
Tandemonium — One tandem bike. Two riders. Total pandemonium.
Coordinate pedaling on a shared tandem bicycle where your pedals are 180° apart. Sync up for maximum speed, or clash and wobble into glorious disaster. It's physics-based co-op chaos at its finest.
Key Features:
- Real Tandem Physics — A shared crank means you must coordinate opposite pedal strokes. Perfect sync = turbo power. Same foot at the same time = you're going nowhere fast.
- Online Co-op Multiplayer — Ride together over peer-to-peer with built-in voice and video chat. Watch your partner panic as you tip.
- Captain & Stoker Roles — The Captain and the Stoker steer, balance and power the pedals. Both must work together or crash spectacularly.
- Multiple Input Methods — Keyboard, gamepad joystick or gyro, or have a friend play on mobile and tilt their phone as a motion controller for an immersive lean experience for everyone.
- Two Courses — Sprint to Grandma's House or endure the long road to The Castle, collecting presents and gems along the way.
- 7 Unique Bikes — From Grandma's Classic to the Banana Delivery, each with its own personality. Unlock holiday bikes through achievements.
- Dynamic Difficulty — Safety Mode for beginners, Daredevil for veterans, and adaptive difficulty that meets you where you are.
- 19 Achievements — Earn badges for speed, distance, flawless rides, perfect sync, and more. Your earned badges orbit your rider for all to see.
- Clip Recording — Save and share your best wipeouts and photo finishes with picture-in-picture compositing video/audio.
- Leaderboards — Track your times solo, together, and by role. Who's the better Captain?
