About

You play as a cell in a chaotic arena of other players. Eat tiny particles to grow your size while avoiding bigger cells that will devour you. Split into smaller cells to dodge attacks or merge with allies for a power boost. Movement is controlled with your mouse or touch, making it easy to pick up but tricky to master. Compete in real time with thousands of others across platforms. The game’s simple physics and fast paced action make it addictive despite the basic graphics. With 15 million monthly active users and a 8.0 rating on Steam, it shows how a stripped down concept can thrive. The leaderboard keeps things competitive even if you play for short bursts. Easy to join but tough to stay top dog.
