The scoring system of tennis is somewhat arcane and the origins are not well understood. It is likely tennis derives from game played in medieval France in which a clock face was used to keep score. Points in the games were incremented in multiples of fifteen (the 'forty' call is thought simply to be short for 'forty-five', and sixty, the top score, was never called as the game ended when this score was reached). Other peculiarities of tennis scoring include the term 'deuce' and 'love'.
Is 'deuce' a corruption of the French phrase 'à deux de jeu' meaning 'two points away from the (end of the) game'?

So, deuce means two and is used for other things besides tennis. Whether the deuce in tennis signifies that a player needs two consecutive points to win the game, or whether it means that the two players have equal scores, is contentious and best left to tennis historians. What we do know is that even though the term has its roots in French, it is not used in the French Open. They prefer égalité at Roland Garros :)
