I unlocked/started the challenge road while in a party of one. I'm now trying to play this mode with more humans. Is this possible? If so, how? I have changed the party to include more human players but the games only ever let the first human play.
My kid unlocked challenge road so I didn't see any of the screens that may have explained if it is only single player. It seems like it would be fine to play with multiple people, especially since this is a party game. I just can't figure out how.
