Super Mario Party Jamboree features the largest selection of boards in the series to date, offering a total of seven distinct game boards. This includes five brand-new boards—such as Goomba Lagoon, Rainbow Galleria, Roll em Raceway, Mega Wigglers Tree Party, and King Bowsers Castle—alongside two remastered classic boards from previous titles. Each board offers unique mechanics and hazards, providing varied strategic experiences for players.

The game supports local multiplayer for up to 4 players on a single Nintendo Switch console. For online play, the title introduces the Koopathlon mode, a competitive event that allows up to 20 players to compete simultaneously in a series of minigames. This massive scale increases the competitive intensity and provides a new way to engage with the Mario Party formula online.

Players can access a comprehensive collection of over 110 minigames, representing the largest count in the history of the Mario Party series. These minigames utilize a variety of control schemes, including button inputs and motion controls via the Joy-Con controllers, ensuring a diverse range of gameplay challenges that test reflexes, strategy, and coordination.

The game includes specialized modes designed to leverage the motion-sensing capabilities of the Joy-Con controllers. Modes such as Paratroopa Flight School and Toads Item Factory require players to physically manipulate the controllers to perform specific actions, such as flapping wings or operating machinery, adding a layer of immersive, active gameplay to the traditional board game experience.
