Including the Regular Balloon Battle, Five Types of Battles to Play!

Balloon Battle
Use items to pop rivals' balloons. You'll get points for every balloon popped.
Renegade Roundup
If the authorities catch all of the renegades, it's game over. If the renegades have even one player remaining when time runs out, they win.
Bob-omb Blast
The only items available are Bob-ombs. Throw them continuously or drop them behind to pop rivals' balloons.
Coin Runners
Compete to have the most coins before the time runs out. The player in first place is shown by a crown.
Shine Thief
Grab the Shine Sprite from the course and hold onto it until the time runs out to win.

There are now eight courses available, each with a different play style.
