Bing rummy is a variant of kalooki (a rummy-based gambling card game) invented in the mining towns of Alaska. The game can be played with 2 to 8 players but works best with 3 to 6 players. It is unknown how the game came to be called “bing” although it may be because of the mining terms: unit of weight equal to 800 pounds, or a pile of rich lead ore. It is probably the second definition that gives the game its name referring to the pile of coins that accumulate throughout the game; especially as it is the Galena lead mines that popularized the term “bing ore”. These mines opened in 1919 about the time the game was developed.
