Trey (Gambling term)

A “trey” is a slang term used in gambling to refer to the number 3. This term is often used in card games to refer to the three-valued card, such as the three of hearts or the three of clubs. In dice games, a “trey” can refer to the combination of three on a single die, or to the total of three that can be rolled with two dice. For example, a player may refer to a pair of threes in their hand as “a pair of treys,” or they may refer to a roll of 3 and 4 on the dice as a “seven trey.”
