FARTNERSHIP.io
Fart Together. Float Together.
A shared round raft, up to 4 players crowding one keyboard, and pure chaotic momentum. Position yourself on the rim, time your bursts to steer downstream, synchronize with crewmates for double velocity, or knock rivals clean off their rafts in Butt Sumo.
Propulsion Audio Deck
Interactive synthesizer deck featuring real-time waveform visualization for each fart signature.
THE TRUMPET
4 Party Game Modes
Jump into co-op river navigation, head-to-head racing, or arena brawls.
Co-Op River Run
Everyone shares a single raft. Walk around the rim to adjust heading, coordinate bursts with teammates for massive jumps, and dodge river hazards.
Raft vs. Raft Race
Crews go head-to-head on the water. Drift sharp river bends, collect boost cans, and draft behind rival slipstreams to snatch first place.
Butt Sumo
A slippery circular platform with no rails. Hip-check opposing players and time your backward bursts to shove everyone else into the water.
Fart Ball & Beans
Even rafts versus odd rafts. Propel a giant floating ball toward the opponent goal while grabbing baked beans for sustained blast pressure.

Low-friction icy waters where momentum carries you far beyond normal steering limits.

Floating flumes elevated high in the open sky. Zero guard rails and sheer drops.
Grand Canal
Grand Canal
The ultimate endurance marathon. Eight checkpoints, every biome hazard, endless blame.
Crew & Gear
Pick from distinctive character models including the Hippo, Crocodile, and Piggy. Equip fun outfits like diapers, kilts, or tutus, and pick a custom audio signature before heading onto the water.
How To Steer
Key principles of raft physics and momentum management.
Rim Position
You stand on the outer rim of the raft. A burst pushes the raft away from your back. Stand behind the raft to propel forward; stand left to steer right.
Crew Sync
Hit your burst key within a split second of a teammate to trigger a synchronized boost. You get double forward propulsion and an acoustic harmony.
Gas Gauge
Continuous holding empties your digestive meter. When dry, you must wait for a brief recharge. Pulse your inputs instead of holding endlessly.
Power Pickups
Snag chili cans for fire blasts, broccoli for smoke trails that confuse opponents, and sodas for rapid burst firing.
