You sit at the bottom, with a computer partner across from you and a computer on each side. Everybody gets ten cards, and the dealer's last card is turned face up to name trump. Follow the suit that was led if you can. The cards you may play are the bright ones, and pressing a dimmed card says why it is not on offer.

If you hold the seven of trumps and the turned-up card is an ace, three, king, queen or jack, a button offers you the swap before you play on the first trick. The computers take it whenever they can.

The computers answer after a short beat. When a deal ends the table itemises the points and you press Next deal. Start again begins a new match. The board shows the trick counts and the totals but not the card points of the deal so far, because counting what has gone is the game. Nothing is saved, so closing the page ends the match.

The same game with people in the other three seats is at play with friends, on one link for each.
