You and a computer partner against the other two, with two jokers on top.
How to play
Four people sit round one table and the two sitting opposite each other are partners. The pack is 52 cards and two jokers, called bloopers. Every deal gives each of you the same number of cards, and that number changes from deal to deal.
The next card off the pack is turned face up and its suit is trumps. The big blooper is the top trump, then the little blooper, then the trump ace down to the two. If the turned card is a blooper, there are no trumps that deal.
Everybody bids once, the seat after the dealer first: pass, a number of tricks, or board, which means every trick. Your side's target is your bid and your partner's added together. Nobody may lead a trump or a blooper until one has been played, unless they bid board. Lead a blooper and everyone else has to play their highest trump, or their lowest if it was the little one.
Make your target and your side scores five for each trick bid and one for each trick over. Miss it and you lose five for each trick bid. A board is ten a card, won or lost. A short game is 14 deals, seven cards down to one and back up, and there is a full game of 26 deals from thirteen cards.
The deal moves one seat on after every deal, here as at any table, so you bid first in the first deal and not in all of them. A tie at the end plays one more deal, with no bidding, and the side with more tricks wins.
