|Shots are performed by pressing one, or both, of the two main buttons (A or B), which make the ball spin in different ways. Pressing a button twice strikes the tennis shot with more power and spin. Additionally, pressing the two buttons in a different order can result in a different type of shot altogether, such as a lob or drop shot. all 4 buttons can be pressed at the same time to hit a very powerful smash shot. The longer a button is pressed before contact is made with the ball, the stronger the shot will be. The control system allows players of all levels to become familiar with the mechanics of the game within a very short time, whilst also encouraging advanced players to take advantage of the variety of shots on offer to come up with different strategies for winning points. A total of seven types of shot are possible using only the one main button of the controller.|
These gameplay mechanics were later brought to the other games of the Mario Tennis series in Mario Tennis GBC, Mario Tennis: Power Tour and Mario Power Tennis.
