 Chance Shots
Chance Shots are a type of shot that only appear when the opponent performs a bad rebound. When this happens, a small colored area will appear on the players side with a symbol of an item or enemy. The color of the symbol will match the color of the panels on the touch screen. To be able to perform one of these chance shots, the player will need to press the correct button, button combination or touching the matching color on the touch screen. If they do not, it will be a regular shot.
Those players who are on the receiving end of the Chance Shot, will experience side effects that may hinder them. They however, could lessen the effect by pressing the correct opposite shot.
Here is a list of the Chance Shots and their effects:
|Red||Fire Flower||Creates a flame shot. When an opponent hits this shot, they will be pushed back drastically.|
|Blue||Blooper||Creates a high curve ball with a blue sparkling trail. The opponent will spin out of control when they hit this.|
|Purple||Star||Creates a Smash Shot.|
|Yellow||Cheep-Cheep||Creates a curving extreme lob that will bounce at the back edge of the court.|
|Gray||Bob-omb||Lower drop shot that a normal drop shot.|
 Game Modes
 Exhibition Mode
Like in the past Mario Tennis games, the exhibition mode is the versus mode of the game. Players are able to pick between singles or doubles match and choose their character and opponents. The can change their hand dominance or star rank. The opponent's CPU difficulty is also chosen after than and will right from easiest to hardest: Novice, Intermediate, Expert, Pro, and Ace. After this, the court will have to be chosen then they can determine the games and sets. Then the match will start.
 Tournament Mode
The Tournament Mode of the game is like the past tournament modes in the Mario Tennis game. This Tournament Mode will have a total of eight cups and the arrangement of the cups are changed. Players can only play in the second set of the cups after the character has a star ranking. This can be done by beating Champions Cup. During Doubles Tournament, only the character they control will get the star rank. When the Champions Cup has been completed, the Pro Difficulty is unlocked. The Final Cup will unlock the Ace difficulty.
After the Cup has been unlocked, players can play them at any time, no matter what character is used. Players will not have to complete the first three cups to beat special cup and earn the Star Rank like previous titles.
Tournament mode is very similar to the tournament mode in the previous Mario Tennis games. However, two more cups are added and the arrangement of the cups are different. Players must have a star ranking to participate in the second set of cups. They can achieve this by beating Special Cup. However, in the Doubles Tournament, only the character they control earns the star rank. Beating Champions Cup unlocks the Pro difficulty, which is more difficult than Expert, while Final Cup unlocks the most difficult COM difficulty for Exhibition Mode, the Ace difficulty.
Once the player has unlocked a cup, he or she can play that cup at any time, no matter what character is being used. As a result, characters do not have to clear all three cups to beat the Special Cup to earn the Star Rank, unlike in the previous titles.
 Special Games
The final game mode is the Special Game mode. These games will have special rules and features added to them that normal gameplay will not have. Some of these modes will be similar to previous Mario titles. Ring Shot will now be included in Special Games instead of an option in Exhibition Mode. Each Special game will have four difficulties and are named according to the special game.
