doop is a duplicate bridge game for four players. The two pairs compare their results against recorded results from national and regional tournaments. Each player has their own deck of cards, and the cards they select are shown in a unique plastic case. After bidding and playing the hand, the pairs can compare your result against match-pointed tournament results.Refills from different tournaments are available.Home Page: http://www.doopbridgesupplies.com/ - BoardGameGeek
