Trips is modern-day casino slang used in poker that refers to a hand comprised of three cards of the same rank. It has the same meaning as three of a kind, which is used more often and considered to be an official term.
In order to land trips in poker variations like Texas Hold’em, a player has to use one or more community cards since players can have only two hole cards. Additionally, to get trips, any combination of different suits will do as long as the cards are of the same rank.
