There are two basic types of cards used in this game: Evidence cards and Gavel cards. The play of the game is based on the Rummy card game, with players trying to make melds (3 or more of a kind) of Evidence cards of the same color to score points. The Gavel cards add a strategic element to the game not found in traditional Rummy. The game ends when at least one player has scored 100 points or more (or 200 points depending on the length of game desired). The player with the highest score wins. In the event of a tie, you must play another hand. You will need a pencil and paper to keep score of each hand.
