The calling player leads to the first trick, and the winner of each trick leads to the next. Suit must be followed, and if possible, the played card must be of higher value than what it is in the current trick. If following the suit is not possible, trump must be played. If neither playing the lead suit, nor playing trump is possible, any card may be played. The player who plays the highest card (any trump is higher than any card of any other suit) wins the trick and leads the next trick.
