Holly Oak is a seasonal trick taking card game. A game typically lasts 3-5 rounds.
Each player must play a card in the current season (if they can). If they cannot, they may play any card.
If its season is the next season (in the cycle Spring, Summer, Fall, Winter, Spring…), then the current season immediately changes to it.
Each trick is won by the highest rank card in the current season at the end of that trick.
