Twenty-nine is a classic trick-taking game, in which the player wins the trick if he/she has a higher card than the opponent in it. The game is played by four players in a fixed partnership, and the winner of each trick leads to the next. The game ends when the last trick has been played.

The player needs to declare a bid, and the amount of the bid, before playing any cards. The player needs to achieve the bid amount or higher, to win the game.

There are two types of bids, one-time and continuous. The latter is played continuously, and the winner of each trick leads to the next.
