Mario Tennis^[a] is a 2000 sports video game developed by Camelot Software Planning and published by Nintendo for the Nintendo 64. Following Mario’s Tennis, it is the second game in the Mario Tennis series. The game is known for being the introduction of Luigi‘s arch-rival, Waluigi, and the re-introduction of Princess Daisy and Birdo.

Camelot developed a Game Boy Color version and it was published under the same title in Western regions and as Mario Tennis GB in Japan.

The N64 version was re-released on the Wii and Wii U Virtual Console, and on the Nintendo Switch Online + Expansion Pack, in 2010, 2015, and 2021 respectively, while the GBC version was re-released on the Nintendo 3DS Virtual Console in 2014.

Gameplay – Mario Tennis

The game uses a control system that differs from most other video tennis games on the market. 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. Both 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 offered to come up with different strategies for winning points. A total of seven types of shot are possible using only the two main buttons of the controller. These gameplay mechanics were later brought to the newer games of the Mario Tennis series.
