.Io games have several common characteristics that set them apart from others. First of all, you always play online, connected to the internet, in total multiplayer mode. Each game, in fact, sees dozens of players face off players all together who try to eliminate each other and excel each other, without any alliance and each with their own game strategy.The other common feature is that they are ultra minimal games, with essential graphics, where players are represented by balls or stylized men or vermicelli just to name a few. Usually, in IO games each player enters into games that are already in progress and that never end, trying to survive and eat the other players to get bigger and bigger. In other .io games, on the other hand, these are games of a few minutes against other players and can also be a competition.
