Mario Tennis/Courts

There are no gimmicks whatsoever but you'll enjoy playing in these standard courts. Here are the rules:
 * Serve diagonally opposite to your opponent. Hitting the net or the opposite side of the court to your opponent is a foul, called a fault. Doing so twice in a row (double fault) will concede points to your opponent.
 * Don't hit areas outside the court. Especially the sides unless you're playing doubles.
 * Scores go in the order of 0 or love, 15, 30, 40 and 50. Scoring 50 wins that one game.
 * If the scores go to Deuce which is 40-40, whoever has the advantage must win at least one more. However you'll lose the advantage if you lose that round.
 * A tiebreaker will happen if a set is drawn 6-6 or 2-2, depending on settings. The rules are pretty much the same as a normal game, but you have to win at least 6 points to win the game.
 * If you're playing closest to the net in doubles, let the ball bounce before you hit or let your ally hit the ball. Don't hit the ball after the serve or you will concede points to your opponent.
 * Aces are tough. You need to put a lot of power and spin on the ball to hit it in one shot.
