Deal nine cards to each of the four players, seated with partners across from one another.

The dealer's neighbor chooses the trump suit for the hand, or opts for a no-trump or all-trump variation.

Players play one card per trick, following the suit led when possible, though trump cards can be played at any time.

In trump suit, card rank order changes so the jack and nine are the strongest cards, unlike other suits.

The highest card of the suit led wins the trick unless beaten by a trump, and the trick winner leads the next one.

After all nine tricks, tally each team's card points plus bonuses for the last trick; the team with more points wins the hand.
