Designed 2001 by K Burns. The game is used as a Tool for Research on Adaptive Cognitive Strategies. Abstract card game played with a deck of double-sided cards. The backs of the cards show black shapes and the fronts of the cards show colored sets. The two tread designs illustrate the odds in the deck. The deck can be adjusted for 1-4 players and different levels of skill. The rules are easy for children to learn yet challenging enough for experts to play. The same game (with minor variations) can be played alone, against others or on teams.
