About the game
№ 001From a cookie crumb to the entire Universe.
GULU: Eat the Universe is a free black hole game for the web browser, made by Toyjar. You play Gulu, a tiny black hole that grows by swallowing anything smaller than itself, from cookie crumbs to cats, cars, cities and planets, across 8 eras until it eats the entire Universe. A run takes about 5 minutes on a phone, tablet or computer.
You are Gulu, a tiny black hole that is never full. Start with crumbs on a picnic blanket, then eat ants, cats, cars, skyscrapers, Everest, the Moon, the Sun… and finally the entire Universe.
Every bite makes you a little bigger. Swallow each era's boss and the camera pulls back into a bigger world. Level-up cards, rival black holes, golden rushes, a daily challenge, and same-seed duel links you can send to a friend.
