There are two main types of cards used in this game: "Evidence cards" and "Gavel cards". Most of the time you will be trying to catch "Jack the Ripper" by making melds (three or more of a kind) of Evidence cards. The Gavel cards will help players trying to catch Jack as well as the player who may be trying to escape. They provide a strong strategic element to the game not found in traditional rummy.
There is also one special "Ripper Escapes" card. With this card, you may decide to try to win the hand by helping Jack the Ripper escape. Playing the Ripper Escapes card ends the hand immediately with lots of points for the person playing it. â€¦
