The cards in each suit are ranked as follows: A, K, Q, J, 10, 9, 8, 7, 6, 5, 4, 3, 2.
The player on the dealer’s left begins the trick. They can play whichever card they choose, excluding those of the spades suit. The trick continues in a clockwise fashion and the other players must follow the suit, if possible. If not, they may play a random card.
If no spade is played during a trick, it is won by the highest value card of the initially played suit. If cards of the spades suit are played, the trick is won by the highest value spade. The winner in the last trick begins the next one.
A spade card cannot be played until:
a spade has been played to trump another trick;
the leader has no other cards besides spades;
Spades are always the trump suit.
