1) if the first player wins at least four points and at least two more matches than the opponent, the player wins a game ).

3) if each contestant has already won at least three balls with the same score, each player is called "Deuce )".

Origin
Tennis was a "jeude Paume" held at the court in the 14th century, originating in the French Louis dynasty (meaning "a game with palm hitting "). Later, the UK was introduced in the 19th century and its improvements were held on turf. Because the most primitive Tennis Sport originated from the court, it is understandable that the scoring method is based on the ground. They scored by the clock that can be switched. Every minute they got the clock turned 1/4, that is, 15 points (aquarter, a moment). Likewise, if you have two minutes, you can set the clock to 30 minutes. Of course, everything is based on their convenience. This is the origin of 15 points and 30 points. As for 40 points, it is odd. It is not a multiple of 15. This is because, in English, it is a dual-syllable, and a "Thirty" in 30 minutes. It is also a two-syllable. However, it is 45 minutes, the English pronunciation "forty-five" has changed to three syllables. At that time, the British thought it was a bit difficult and did not comply with the "convenience" principle, so we changed it to the same two-syllable 40 points (forty ). This is the logic of 40 points.
