features a wide variety of human and Mario characters for the player to use. The game also features mini-games such as a tennis version of a shooting gallery where, as Donkey Kong, the player must hit the banana targets on the wall to earn points in a set amount of time.

An RPG mode appears on the Game Boy Color version, which is not in the N64 version. In this mode, players begin as a rookie tennis player at the Royal Tennis Academy, who must build up his/her skill (by leveling-up) through training and practice matches before entering various tournaments. The aim of this mode is to be crowned champion at the academy, although a surprise awaits those who attain this goal.
