When I was in college many late nights were spent playing Rook.
Rook is a card game similar to Euchre. The object is to take the “trick,” the cards laid down during each round. One easy way to do that is to lay down a “trump card.” A trump card is a card that outranks all of the other cards, with the rook card being the highest trump card in the game. It’s always a good game when you have a handful of trump cards, including the rook card.
