Players take turns placing numbered tiles in runs (consecutive numbers of the same color, like 2, 3, 4 in red) and groups (three or more of the same number in different colors, like a red 9, a blue 9, and a black 9), rummy style. The Joker tiles add to the fun; they can be any color or number.The object is to be the first to play every tile on your rack. Players keep track of who wins each round-the player who wins the most rounds wins this time-tested tile game! There’s also a point system for use as a tie-breaker.
