Mario and his friends are throwing a party and you're invited.
It's their biggest party yet, with seventy totally new mini-games and five new adventure boards.
You'll be the life of the party as you smash, pound and smash your opponents in a multiplayer melee or go head-to-head in the new two-player duel mode.
You can even unlock new characters in the single player challenge.
With so much fun and excitement, it's a party you just have to crash!
