About .io games
.io games are quick online arenas where everyone starts small and tries to grow: eat, claim territory, or survive the longest while other players try to stop you. There is no account and no download, which is why the genre took off in browsers.
The first rounds are for learning the map. Stay near the edges while you are small, avoid bigger players, and grab the easy pickings. Once you understand how the arena flows, you can start hunting.
