Games like Agar.io you can play in your browser
8 games · Updated October 17, 2026
Agar.io is listed here too, where you eat smaller cells to grow bigger online, and these games share its loop of eat, grow and don't get eaten, free in a browser tab. In Starpit.io you grow from a brown dwarf into a black hole by absorbing debris and smaller players, and you need at least 1.3 times a player's mass to absorb them. Darwin Royale starts you as a single cell in a shrinking arena, against players or bots: eat, fight and evolve to be the last cell standing.
In mope.io you eat, evolve and climb the food chain, and EvoWorld.io evolves you from a fly into bigger creatures, both online. Slither.io grows a giant snake from glowing dots. In InkFish you eat smaller fish and grow without getting eaten, and in Eat the World you grow a hole that swallows the city.
