Iowa Gambling Task

Iowa Gambling Task is gambling card game developed for Dr. Wiezel, a professor at ASU, for a psychological experiment. There are four decks (A, B, C, and D). Each deck has cards that consist of either wins or losses. The player must draw a card from any deck he/she decides and try to figure out which deck is the best one to pick from based on the number of times he/she wins from each deck. The game ends when all the cards from each deck are drawn.
