ELI5: Explain Like I'm 5

Congestion game

A congestion game is when a group of people try to compete to use limited resources. For example, let's say there are 10 people and only 3 pieces of cake left. Whoever can claim the cake first will get it, but the other players will have to find something else to eat. The goal in a congestion game is to be the quickest at claiming the cake so that there is more left for other people.
