IO is a massively multiplayer online action game. Players control the cell or the worm in a map to swallow the colorful bright spots. The goal is to gain as much mass as possible by eating colorful spots and cells or worms smaller than your cells or worms while dodging the bigger worms or cells. Try you best to swallow colorful spots as many as possible. You can surround other smaller cells or worms to make your cells or worms longer. Or you can attack longer cells or worms with allying with other players to threaten bigger cells or worms in a dilemma. Defeat other rivals and make your cell or worm the longest.
