If you win your first point, your score is 15. Win a second point and your score is 30. Third point - 40. If you win a fourth point, the game is yours, unless you and your opponent have won three points - in this case, the score is known as deuce and you must win by two clear points. If you win the point at deuce, the score is called advantage to you and you must win the next point to win the game, otherwise the score reverts to deuce.

The historical origins of the 15, 30, 40 and so on are believed to be derived from the presence of a clock face at the end of the court. A quarter move of the appropriate hand was made after each point, with the score being called as 15, 30, or 45 as the case might be. When the hand moved to 60, making the complete circuit, that was game.

Winning six games wins a set; except that you must win by a margin of two games. Players change ends when the total number of games is an odd number (e.g. 1-0, 2-1, 3-2). The tie-break system of scoring is often adopted to decide a set which reaches six games all.
A match can be best of 3 sets (you need to win 2 sets to win the match) or best of 5 sets (you need to win 3 sets to win the match).  

In a tie-break, the player who first wins seven points wins the game and the set, provided there is a margin of at least two points. If the score reaches six points all, the tie-break continues until the two point margin is achieved. Numerical scoring is used (e.g. 1-0, 2-0, 2-1, 3-1, etc).

The player whose turn it is to serve serves the first point (from the right side of the court). The other player serves the second point (from the left) and the third point (from the right). Each player then serves alternately for two consecutive points (first from the left and then from the right). Players change ends after every six points (and at the conclusion of the tie-break). The first game of the next set is served by the player who did not start the tie-break.
