About this game
This game is inspired by a public task from experimental psychology about choosing when outcomes are uncertain and learning from what happens. It is an original version made for this site, not the task itself.
When you finish, the summary of your play style shows which end of the "Learning" bar your way of playing leans toward in this session: "Sticks with the familiar" or "Explores options". It is not a score or a percentile, it does not compare you with other people, and neither end is better than the other.
