Public goods game

The public goods game is a game about cooperation. In this game, everyone starts off with a certain amount of money. Then, each person can decide whether to keep the money for themselves, or to put some (or all) of it into a shared pot. At the end, the money in the pot is multiplied, and everyone gets a share of the pot. The goal is to try to figure out how much money everyone should put in the pot so that everyone can get the most money back. It's a cooperative game that rewards you when you work together with other people!
