How are points earned in tennis?

To earn points in tennis one person serves the ball in the service box and the opponent hits back to the server until either the server misses it, the tennis ball goes out of bounds (the person who hit the ball out would lose the point), or if a player touches the net the other player gets the point. The score goes love, 15,30,40 game. At 40-40 it's called deuce and you have to win 2 points in a row to win the game you need 6 games to win a set unless it's tied at 6-6 then you play a tiebreaker to 7 and you win by 2 and every 6 points played you switch sides. People usually play 2 out of 3 sets. Each game you switch on who was serving.
