Bridge Flipper

A bridge flipper is an aide-memoire sometimes used by students of the game of contract bridge. It can be employed in both rubber bridge and duplicate bridge. Most such publications focus on the auction phase of the game. The intention behind the flipper is that by having it by the player's side, he or she will be able to make swift bidding decisions as the auction progresses. However Law 40B2(d) of the Laws of Duplicate Bridge states that "a player is not entitled to any aids to his memory, calculation or technique during the auction period and play."
