SUMOWBALL
Roll, grow, and knock your opponents off the island in this physics-based multiplayer party game. Master momentum, build the biggest snowball, and be the last penguin standing.
SUMOWBALL
Roll bigger. Hit harder. Stay on the island.
Every match begins the same.
Tiny snowballs.
A snowy island.
A group of penguins with the exact same goal.
Roll across the snow to grow your snowball. The larger it becomes, the harder you hit—but the harder it is to control. Every decision is a balance between power, speed, and maneuverability.
There are no weapons.
There are no abilities.
There are no health bars.
Only physics, momentum, and the edge of the island.
Master the Snowball
Your snowball is everything.
It isn't a vehicle. It isn't equipment.
It is your movement, your weapon, and your greatest weakness.
Movement comes from real rolling physics. Snow naturally makes your snowball grow, while ice takes away your grip. Every collision is determined by momentum and closing speed, rewarding timing and positioning instead of arbitrary damage values.
Grow too small and you'll struggle to push anyone.
Grow too large and you may not turn fast enough to survive.
Finding the perfect balance is what separates the winners from everyone else.
Only One Penguin Wins
The island won't save you forever.
As the match progresses, the arena slowly collapses into the sea, forcing every surviving penguin into increasingly chaotic encounters.
Space disappears.
Escapes become impossible.
Eventually, someone has to fall.
Be the last penguin standing.
