Rummikub is a tile-based game for two to four players, combining elements of the card games rummy and mahjong. There are 104 number tiles in the game. Players have 14 or 16 tiles initially and take turns putting down tiles from their racks into sets of at least three, drawing a tile if they cannot play.
Rummikub was invented by Ephraim Hertzano, a Romanian-born Jew, who immigrated to Israel in the 1940s. He hand-made the first sets with his family in the backyard of his home. Hertzano sold these sets door-to-door and on a consignment basis at small shops. Over the years it became an industry in itself and the family licensed it to other countries.
