What is it called when the score given to a player who has won three points in a game?

When a player has won three points in a game, the score is referred to as "forty." In tennis, the progression of points goes from 0 (love) to 15, then 30, and finally to 40 when a player wins three points. If the player wins a fourth point, they win the game, provided they have a two-point lead.
