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. 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 played as any color or number. Be the first player to play every tile on your rack to win. Rummikub is ideal for people of different ages to play together, and reinforces STEM and STEAM concepts such as sequencing, pattern recognition, and planning skills. This set includes 106 playing tiles with bright over-sized numbers, 4 plastic tile-holder racks, and complete instructions. For 2-4 players, ages 8 and up.
