With more than 55 million units sold, Rummikub is one of the world's best-selling and most-played games! It's really 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. Players take turns placing numbered tiles in runs (consecutive numbers of the same color) and groups (three or more of the same number in different colors), rummy style. 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 and can be used as any color or number. Be the first player to play every tile on your rack to win! Reinforces STEM skills like sequencing, pattern recognition and planning. Rummikub includes 106 high-quality plastic tiles, 4 plastic tile-holder racks, and complete instructions.
