There are a total of 4 card suits: (brains),
(speed),
(strength) and
(love).
Normally, the player who played the highest-valued card of the lead suit wins the trick.
However, (love) is the trump suit, so its cards take priority. If the trick contains any
(love) cards, the player who played the highest-valued love
card wins the trick, even if love is not the lead suit.
