How to play
This table needs both seats before the first card is dealt, so the host has one link to send and picks how long the match is, first to 300 or first to 500. Nothing happens until the other person arrives.
Six cards each, and a card turned up whose suit is trumps. Their hand shows as backs and a number, and so does the stock: you can see how many cards are left, never which ones. Melds that have been laid are face up for both of you, and a folded list under the table shows every card played this hand.
On your turn click a card to play it. When you win one of the first ten tricks, a panel offers the swap of the seven of trumps if you hold it and one checkbox for every meld you can lay, all ticked to start, and you press the one button to lay them and draw. The panel appears even with nothing to lay, so the other seat learns nothing from it. Cards you cannot play are dimmed, and the line above your hand says why.
At the end of a hand the table shows the count, and both of you press the deal button to go on. The first to the target wins. Chat is always on at the table, and voice only if the host switched it on when they made it.
