A mathematical game where the object is to get rid of all of your cards. Players are dealt a hand of cards numbered 1-10 or containing a letter from the game's title (these are given numeric values before the game starts, typically 11-15). Players then take turns rolling three dice. Each player then discards cards whose values correspond to a combination of the dice. A combination is valid if it uses all three dice and standard mathematical operations applied in any order.
