Paddle in hand, the river ahead. SUP is a lighthearted rogue-lite paddleboarding adventure packed with hazards, hidden shortcuts, and wondrous creatures. One paddle. One run. One chance to not wipe out spectacularly — how far can you ride?

Four Biomes, Eight Levels
Journey through four handcrafted river environments — each with its own look, feel, and dangers. From misty redwood forests to scorching desert canyons, every biome brings new hazards and new ways to wipe out.

Momentum-Based Movement
Your board carries real weight. Speed builds, corners punish, and the current has opinions. Learning to read the river is the difference between a clean run and a spectacular wipeout.

Shops and Upgrades
Spend your run currency between levels on items and upgrades that change how you play. Build a loadout, take risks, and go further than your last attempt.

Hidden Shortcuts
The river rewards exploration. Find alternate lines that shave time, skip danger, or open up new routes entirely.

Speedrun Mechanics
For players chasing mastery, SUP rewards precision. Advanced movement techniques and hidden rewards give skilled players room to push their limits and climb the leaderboard.
