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 and groups, rummy style. The 'board' continually changes as players adjust the tiles on the table. Be the first player to play every tile on your rack to win.
