Rummikub is a tile-based game for two to four players, combines elements of the card game rummy and mahjong.
Rummikub was invented by Ephraim Hertzano, a Romanian-born Jew, who immigrated to Mandate Palestine in the early 1930s. He hand-made the first sets with his family in the backyard of his home. The game combines elements of rummy and mahjong. Hertzano sold the first sets door-to-door and on a consignment basis at small shops. Over the years, the family licensed it to other countries and it became Israel’s #1 export game. In 1977, it became a bestselling game in the United States.
Hertzano's Official Rummikub Book, published in 1978, describes three different versions of the game: American, Sabra and International. Modern Rummikub sets include only the Sabra version rules, with no mention of the others, and there are variations in the rules between publishers.
