The highest trump, or, if no trump is played, the highest-ordered card of the suit lead takes the trick. In case of ties, the first highest card played wins the trick. Only two cards are considered doubles(Or Pair), so two different-suited trump rank cards, two ordinary non-trump cards with the same value, or a combination of a red joker and a black joker are not counted. For example, if 7♣ is trump, 7♠-7, or Q♠-Q are not considered doubles despite them being of equal rank (or in the first case, both in the trump suit). After a double-cards lead, other players must also follow suit with double cards, if they have them; for players who do not have double cards in the suit lead, they must play separate cards in the same suit if they have them. Only after playing any cards in the lead suit, they may play any cards from other suits, or a double from the trump suit to "ruff" the trick. In this case, the highest-ordered trump double, if it is played, wins the trick; otherwise, the highest-ordered double in the suit lead wins. Two singles may not beat a double even if they are both higher-ordered than the double (for trump 7♣, 9-9 beats J-Q or even J♣-Q♣, if a diamond double was led). Consecutive double cards(Tractor) If a player has consecutive pairs of cards(or Tractor) in the same suit (trump or non-trump), he or she may lead it as a group. In this case, other players must follow suit by playing cards according to the following priority, if they have them: Other consecutive doubles(Tractor) in the same suit Other doubles in the same suit Other singles in the same suit The first combination, if all consecutive and of a greater order than the suit lead, wins the trick. Only when a player does not have any other card in the suit played, then he is allowed to play cards of other suits, or ruff the combination with the same number of consecutive pairs in the trump suit. The table below describes whether some combinations are considered as consecutive doubles; if otherwise, , but will instead follow the multiple-cards combination rules . Combination of multiple cards A player may lead a combination of multiple cards(甩牌) if he has them, provided that each of the singles or doubles played are the largest in the suit and
