You against two computers. Bid to play alone, follow suit, and hearts double every stake.
How to play
Ten cards each, and two more for the opener: put two down as the talon and bid. Each seat then passes, takes the talon, puts two down and bids higher, or bids higher unseen. Three passes in a row end the auction, and the last bidder plays alone against the other two, naming the trump first after a minor-suit bid.
Follow suit if you can, then play a trump if you have one, and beat the best card whenever you can. Cards you cannot play are dimmed, and pressing one says why. Before your first card, as a defender, you may kontra a part you think will fail. Pick a match of 6, 9 or 12 deals above the table, and press Next deal after each count.
The same game with friends instead of the computers is at a table of its own, three seats and a link for each of the other two.
