Bieden is a card game played mainly in flanders. While variants like "manielen" have their online versions, there wasn't a public site to play bieden yet. That's why I've used python to create this wonderful game for you and your friends.
The game is a cardgame for four players. It consists of three phases: the dealing, the bidding and laying cards. First everyone gets their cards, using a specific dealing method. Then the players can bid, which means they say how much points they will be able to get. The person who has bid the most, can start the game by laying a first card. Then all cards are laid one by one until there are no cards left. The points of the cards get counted to determine whether the highest bidder has gotten the points he said he would.
For a more detailed version of the rules, one can read the documentation or the wikipedia page, but the rules differ a little bit.
