Start as a tiny meteor. Devour the universe. Evolve into a black hole! Enter a cosmic arena where ten planets compete for resources and survival. Use gravity to attract space debris, grow your planet, build a powerful team of Orbital Companions, and smash through weaker rivals. Devour and evolve Approach space debris and pull it toward your planet with gravity. Watch the fragments orbit, move closer, and become part of your growing world. Collect resources and evolve from Meteor to Planet, Star, Red Giant, Supernova, Neutron Star, and finally Black Hole. Every evolution changes your appearance and increases your combat power. Crash into your enemies Your planet is not only something to protect—it is also your greatest weapon. Accelerate into enemy planets, knock them away, and break resources from their surface. Larger and stronger planets can overpower weaker targets, but both sides take damage during a direct collision. Defeated planets explode into collectible debris. Rush in to claim the rewards before another rival steals them. Build your Orbital team Each Orbital has its own health. When destroyed, its ability temporarily disappears. After a short recovery period, it rebuilds and returns to battle. Choose your evolution As your planet grows, choose one of three evolution options. Gain a new Orbital, strengthen an existing companion, or unlock a new ability. Focus on collisions, ranged attacks, recovery, speed, or resource collection. Create a different build in every match. Fight for first place Face nine rival planets in each arena. Collect resources, hunt weakened enemies, steal debris from battles, and escape from stronger opponents. Choose the right moment to attack, survive until the end, or defeat every rival to claim first place. Earn rewards, upgrade your planet and Orbitals, unlock new abilities, and challenge higher cosmic arenas. Can you grow from a tiny meteor into the black hole that devours everything?
