A deuce is one of the number two cards in a deck of cards. Or, in tennis, a deuce is a tie that must be broken by someone scoring two points in a row. When playing games, remember that when you hear deuce, it comes down to two.

There are two main meanings of deuce, both of which relate to the number two. The first is a playing card: the two of clubs, diamonds, hearts, or spades is called a deuce. In sports like tennis and ping pong, a deuce is a tie. One player must score two consecutive points to break the deuce and win. This can go on for a while if the players are well-matched. A hard-fought point could feature one deuce after another.
