Compete against seven other players (computers) and only one player (computer) will win! You play as the only human player in the game. After starting the game, there will be a machine in front of you; you can choose two actions: throw a jellyfish or do nothing. If you put in a jellyfish, the opposite side can get 3 jellyfish, and vice versa. You can [cooperate] with your opponent, which can achieve a win-win situation and each get two jellyfish. But obviously if one of the parties [does not cooperate] and the other party [cooperates], then obviously: not only can you get more, but you can also weaken the strength of the opponent. —— After all, there is only one winner in the end! But the other side is not an idiot. If you keep not cooperating, although you may earn a temporary advantage, it will be a stupid behavior after all. What? If everyone enjoys cooperating harmoniously, isn't everyone number one? ……… Although it does make sense, and some people do think so, not everyone is equally kind!
