COIN is a trick taking card game for four players, played over several Rounds. There are no Trumps. Instead, each player controls 1 of the 4 Colors, and will play cards from their own Color deck (13 cards, each with a Value of 1-13 and worth 1-3 Coins of their Color on the front). The back of each card has no Value and 1 Gray Coin. Cards can be played face up or face down, each with a different result.
Each Round, the 8 Trick cards are seeded randomly (and secretly) from each player’s deck. Meaning that every round, the Tricks, and the cards available to each player, will be different. At the end of 8 Tricks, the players score points for the Coins (and maybe cards) in their Bank (score area) different ways. At the end of several Rounds, the player with the most Points wins!
