It’s no surprise that Rummikub is so popular–it has all the elements that make a great game: it’s easy to learn and fast moving, it’s different every time it’s played, it combines luck and strategy, and it changes quickly so every player has a chance to win until the very end. And with more than 70 million units sold, Rummikub is one of the world’s best-selling, and most-played, games. 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). It’s easy to learn, but packed with strategy–the “board” changes all the time as players adjust the tiles on the table. The Joker tiles add to the fun; they can be any color or number. The object is to be the first player 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).
