Check out all kinds of additional modes, like the 20-player online Koopathlon. Race across the party board in Koopathlon, a series-first 20-player online competition to see who can rack up the highest scores in minigames like the fast-paced Lane Change. The higher your score in each round, the faster you’ll get to the goal. Koopathlon is just one of a slew of additional modes—there’s something for every kind of Mario Party enjoyer! Party online on us—a 3-month Nintendo Switch Online Individual Membership is included! You’ll need an Internet connection and a Nintendo Switch Online membership to play in online modes, but don’t worry if you’re not a current Nintendo Switch Online member.
