The party is back and bigger than ever in the Mario Party 9 game for Wii, featuring all-new ways to play! For the first time in the franchise, boss battles crash the party and challenge players to compete to defeat a common enemy. In addition, players now travel across stages together in a vehicle towards a common goal - overcoming obstacles, battling bosses, and collecting Mini Stars stolen by Bowser and his minions.

For the first time in the Mario Party franchise, each stage culminates in a Boss Battle. Collectively, players must combine their strength to defeat classic foes such as Bowser and King Boo while still playing competitively to boost their own individual scores. In another first for the series, players ride across stages together in special vehicles. Players take turns as Captain of the vehicle by hitting Dice Blocks to move the party forward, hoping to land on lucky spaces.

In Mario Party 9, each themed stage has a clear destination point but with multiple paths along the way, so no two games will play the same. From Toad Road to Boo’s Horror Castle, players will encounter a wide variety of familiar Mario franchise elements in new environments that can be enjoyed solo or with friends.

No time to play through an entire stage? New minigame modes let players enjoy the action in smaller chunks of time. They can hone their skills at any minigame in Free Play mode or try the Extras mode that includes Goomba Bowling and the puzzle-based Castle Clearout.
