How this test works

This game is about learning which choices pay off when nobody tells you the rules. You start with 2,000 points and pick 100 cards from four decks. Every card wins points, and some cards also take points away. Two decks win big but lose more over time. The other two win less but come out ahead. Your score is your picks from the good decks minus your picks from the bad decks. It follows a card task first published in 1994.
