Discover The Evolution of Trust

Nicky Case starts this simulation with a simple choice. Give up a coin so your opponent receives three, or keep it. After a few rounds, compare strategies in simulated tournaments. The sandbox lets you change the rules and see when cooperation holds up against cheating. The title screen links to Ayowel’s French translation.
