The game plays like Mario Party 1-8. The players walk around separately in non-linear boards, and the one with the most Stars at the end wins. However, the player can play in Mario Party 9-style, where the one with the most Mini-Stars when the games ends wins. This is called "Mini-Star mode". The player can choose to play either in a mode where the player with the most Stars/Mini-Stars wins (called "Classic Party mode") or in a race to the finish (called "Race to the Finish mode"). Items appear in this game, and there are new items called Battle Items that can be used to attack enemies. Attacked enemies lose coins and are knocked back a few spaces. Mini-bosses and bosses return from Mario Party 9.
Party Mode (1-4 players)
Play in any board you have unlocked.
Minigame Stadium (1-4 players)
This mode is played in a special board exclusive to this mode. The character with the most coins when the game ends wins. The only spaces here are common and 1-player minigame spaces. The only way of earning coins here is to win 10 minigames.
Minigame Marathon (1 player)
Beat as many minigames as you can. The game ends when you get any placement other than first place.
The game has 28 playable characters, 18 starter and 10 unlockable. There is also the option to play as a Mii. The unlockable characters can be unlocked by beating them in story mode or getting a certain number of Stars/Mini Stars.
Each character has a default partner that they are partnered with in story mode. Also, they all have a color that represents them in minigames. e.g. in the Swimmy Cheep Cheeps minigame, the character's Cheep Cheep submarine will be of the character's color.
