To unlock this board, you need to beat the other five boards in Solo Cruise Vs. CPU.
The setting of this board is a carnival-type layout inside of a volcano. The are four islands.
For Bowser Time, Bowser sinks the island with the star. Anyone on the sunken island will go to Start and lose half of their coins. If you reach the star space, you can buy it for 20 coins. You can change which island you're on by taking a two-way bridge or by landing on a Bowser Cannon Green Space. You can summon Koopa Kid.
Solo Cruise[edit]
Reach the center island with a star to fight Bowser at Bowser's Lovely Lift. It will probably take more than one star to reach the top and win.
Bowser Cannons[edit]
One can be found on each island. They launch you to a different island.
South Island[edit]
This is the island you'll be directed onto at the beginning. The very first Green Space changes the position of the star. The Happy Hopscotch Obstacle Course is located on the eastern end. Use 
(or 
) to choose a pylon. If it sinks into the lava, you lose ten coins. If you pick the stable pylon three times, you'll get a star. In team battle, the second player can try to reach the star if the leader falls off. The stable pylons will be the same.
East Island[edit]
Land in front of the Bowser Torch to get toasted! You'll lose ten coins.
North Island[edit]
You can access Koopa Kid Boxing from the west side or the east side. Press 
furiously to beat Koopa Kid. In team battle the second player will fight Koopa Kid if the leader loses. Each player that falls off will lose ten coins. The net gain for winning is ten coins.
West Island[edit]
The Green Space on the north side will put you on a roller coaster. You'll get dumped on the south side. Press (or 
and 
) to jump for coins. The speed will vary with the slope of the track.
