Mario Tennis Open

Mario Tennis Open is the latest installment in the Mario Tennis game series. It is for the Nintendo 3DS, released first on May 20, 2012. The game features gyroscope support and online multiplayer (using the Nintendo Network procedures).

Gameplay
The gameplay features the traditional basic elements from previous Mario Tennis games, utilizing the buttons of the 3DS during gameplay single or multiplayer matches. Players can perform various different tennis shots by selecting the shot panels on the touch screen.

Menus

 * (A) - Confirms command
 * (B) - Cancels command. If players win an exhibition match, they can press this button to automatically return to the main menu.
 * (Start) - During a match, this button stops the game and opens a menu that contain choices such as viewing game rules, setting gyroscope controls, choosing to restart matches, and canceling matches.
 * (L) - Toggles between the character's dominant hand.
 * (R) - Toggles between the character's star rank. In multiplayer, this is based on the data of player who created the room. Therefore, the player who has created room needs to have his or her characters starred if members of the room want to give their characters a star rank.

Matches
When preparing a shot, note that the buttons will function similarly to a dead-key on a keyboard.
 * (A) - Performs a topspin.
 * (B) - Performs a slice.
 * (X) - Performs a simple shot. This button automatically performs a weak version of the appropriate shot.
 * (Y) - Performs a flat shot. This button is used for Smash Shots as well. Note that Smash Shots and Purple Chance Shots are different shots.
 * (A) → (B) - Performs a lob.
 * (B) → (A) - Performs a drop shot.
 * (A)/(B)/(Y) While the opponent is receiving or serving the ball, or while your doubles partner is serving - The character performs a taunt that makes his or her shots better until someone scores.
 * (L) - If the player is charging a shot, this button cancels the charge.
 * (L) During doubles matches - Creates a speech bubble above your characters head saying "Got it!"
 * (R) - Performs a Lunge.
 * (L)/(R) While any player is serving - Cycles through three different touch screen layouts.

Tournaments
Like in all Mario Tennis games, Tournaments can be played either in Singles or Doubles. Every tournament consists of a standard 8 player tournament. The first 4 tournaments you can play in are the: You must play through each of them in order to unlock the next one. These 4 tournaments make up the World Open.
 * Mushroom Cup
 * Flower Cup
 * Banana Cup
 * Champions Cup

The Mushroom Cup is played on the Mushroom Valley court, and is the easiest of all the tournaments

The Flower Cup is played on the Wario Dunes court, and is a little harder than the Mushroom Cup

The Banana Cup is played on the DK Jungle court, and is harder still.

The Champions Cup is played on the Mario Stadium Courts, which is played on 3 different courts, the Hard Court, the Clay Court, and the Grass Court. This cup is the hardest of the 4 cups

After you complete the Champions Cup, you are then allowed to play in the Star Open, which consists of 4 new cups, which are as follows: Once again, you must play through each of them in order to unlock the next one.
 * 1-Up Mushroom Cup
 * Ice Flower Cup
 * Shell Cup
 * Final Cup

The 1-Up Mushroom Cup is played on the Peach's Palace Court, and is the easiest of the Star Open cups

The Ice Flower Cup is played on the Penguin Iceberg Court, and is a little harder than the 1-Up Mushroom Cup

The Shell Cup is played on the Bowser's Castle Court, and is harder still.

The Final Cup is played on the Galaxy Arena Court, and is the toughest of all the 8 cups.

It is worth noting that after you complete the World Open on singles, you unlock the Star version of whichever character you played as. You can only play as a Star player in the Star Open.

Exhibitions
In Exhibition Mode, you just simply play tennis matches, either Singles or Doubles. You get to pick the difficulty level of the CPU, either Novice, Intermediate, Expert, and later on, Pro and Ace. You then pick whatever Court you want to play on. Finally you pick how many sets and games you want to play, either 1, 3, or 5 sets, and either 2, 4, or 6 games to a set.

Special Games
There are 4 different Special Games that you can play: In Ring Shot, you must hit the ball through golden rings in order to earn a certain amount of points before time is up. You can get more points by hitting the ball through 2 or 3 or even 4 rings at once than just hitting it through one at a time.
 * Ring Shot
 * Super Mario Tennis
 * Galaxy Rally
 * Ink Showdown

In Super Mario Tennis, you go through classic Super Mario Bros stages, and must get the ball to the flagpole at the end before time runs out. You can add on to the time you have left by killing enemies or collecting coins.

In Galaxy Rally, you must complete a certain number of rallys without missing 3 times. It becomes challenging, because the opposite court side consists of 4 disappearing tiles that disappear each time you hit them, thus creating a hole in the court in which you cannot hit balls to. As soon as you hit another tile though, the previous hole gets filled back in and a new hole appears in the space that you just hit.

In Ink Showdown, you must score a certain amount of return aces(not letting the opponent return the ball). Sometimes you will also get ink balls spit at you, and if you dont hit them, they ink up your screen, making it harder to see where the next ball will be coming from.

Each of these games has 4 different difficulty levels that get harder with each level, but make it possible to earn more coins as well.

By playing these games, you earn Coins, and you can use the coins to buy clothing parts in the Item Store

Chance Shots
Chance Shots may appear if the opponent performs a bad rebound, in that case, a small colored area with a symbol of a Mario enemy or item appears in the player's court. To perform a chance shot, players have to perform the shot whose color corresponds to the colored area when they are in the area, either by pressing the correct button or button combination or by touching the matching color on the touch screen, otherwise, the shot is a normal shot. However, players can perform a simple shot that automatically selects the appropriate shot, but this Chance Shot is weaker. Players on the receiving end of a Chance Shot may nullify the effect by using a shot with an opposing spin.
