《Mario Party 9》 is a party game developed by NDcube and published by Nintendo for the Wii. It was first released in Europe on March 2, 2012, and subsequently launched in North America, Australia, and Japan. As the ninth installment in the Mario Party series, it is the second and final Mario game released on the Wii platform. The game was localized in Chinese for the first time and follows a similar board game format as its predecessors, but introduces many new gameplay mechanics and improvements, making it more fun and challenging.

The game features classic Mario series characters, including Mario, Luigi, Princess Peach, Yoshi, and more. Up to four players can play simultaneously, participating in various mini-games and competitions to win. The objective is to move around the game board, collect Mini Stars, and ultimately become the winner.

The story begins one night when Mario and his friends are outside Princess Peach's castle, watching the stars in the sky. They notice Bowser and Bowser Jr. in a spaceship, using a machine to vacuum up the Mini Stars into a filler device. Mario and his friends set out on a rescue mission to save the Mini Stars. Unlike previous games where players moved separately, all players now travel together in a vehicle on the game board.

Movement on the game board is determined by rolling dice, with each player taking turns to move and participate in mini-games. There are various types of mini-games, including racing, skill-based, and luck-based games, each with unique controls. Players use the Wii Remote to roll dice, swing, point, and press buttons.

The game features a total of 80 mini-games, including making pizzas, escaping from haunted mansions, and snowmobile races. Each game board has unique designs and themes, such as haunted mansions, pirate ships, and space stations. The board is filled with various special events and challenges, requiring strategic path selection to collect more Mini Stars. Additionally, the story mode requires players to complete a series of levels and challenges to rescue the Mini Stars captured by Bowser.

Players can unlock additional content and rewards by meeting certain conditions. For example, winning multiple times in Party Mode can unlock new characters and game boards. Completing the story mode can unlock Bowser's levels and more mini-games. Players can also collect points in the game to purchase rewards and unlock items.
