The term GAME STRUCTURE can be defined as a BRIDGE, which is a 6 letter word. BRIDGE is a card GAME that originated in the 19th century and is played by four players in two competing partnerships. The GAME consists of a series of deals with the objective of scoring points by taking tricks. The STRUCTURE of the GAME is based on the bidding process, where each player bids on the number of tricks they believe they can take. The highest bidder then names the trump suit and the other players must follow suit. The team that takes the most tricks wins the GAME.
