Rook is a trump-based, trick-taking game played using a deck of Rook playing cards. It was initially sold in 1906 by Parker Brothers. The Rook deck is very similar to a standard deck of cards, but has only numbers from 1-14 in four colors (no face cards or card suits (spades, etc.)). The base game is a 4-player partnership game with the 1's, 2's, 3's, and 4's removed for a deck of 41 cards (with the Rook card). Each hand, players will bid for Trump, and then the partnership that won the bid must make the amount of points bid in the hand. Play of every trick is similar to Whist games like Bridge. The card led has to be followed by a card of the same color. A player can play a trump color if they have none of the color led. The highest card of the color led will win the trick, unless the trick is trumped, and then the highest trump wins the trick. The Rook card may be played at any time, and always wins the trick. Unlike Whist or Bridge, the amount of tricks is not critical, but certain count cards (5's, 10's, 14's, and the Rook card) taken in tricks are worth points, which is how the game is scored.

Deluxe Rook comes with a deck of 56 premium-quality, numerical rook bird cards (there are no face cards) and the unique ROOK bird card. It also comes with 28-page guide booklet with rules for many popular ROOK variations, including "Kentucky Discard"/Tournament Rook.
