In odds & even, a trick-taking game, the cards have different suit backs depending upon if the number on the front is odd or even. In each hand, rather than a suit being trump, either odd or even numbers are trump. Each player is dealt a hand which is half odd cards and half even cards. The players look at the half which is not trump and makes a bid on how many tricks they will win this hand. Then, each player picks up their trump cards and drafts them, choosing 1 and passing the others, until there are no cards to pass. Players complete a number of rounds equal to the number of players and earn points for hitting their bid and other ways. The player with the most points wins.
