- Balloon Battle: At the beginning of the game, players start off with five balloons. They must use items to pop other players' balloons. If all of a player's balloons are popped, they will respawn with three. The player or team that pops the most balloons by the time or frag limit wins.
- Shine Thief:
- Bob-omb Blast:
- Coin Runners:
- Renegade Roundup:
- Balloon Royale: Similar to Balloon Battle. But once you lose all of your balloons, you won't respawn. Last man or team standing wins.
- Pass the Bob-omb: Opposite of Shine Thief. At the beginning of the game, a random player receives a non-throwable Bob-omb which will explode in 30 seconds. They can pass on the item to another player by touching them. When it explodes, the player holding the Bom-omb will be eliminated as well as anyone within the blast radius. The process repeats until one remains or everybody is eliminated. The player with the Bob-omb is slightly faster than the others.
- Capture the Shine: Based of Capture the Flag. Players are split into two teams, and the arena is divided into two designated halves for each team. Each team has a Shine, and they must bring the opposing team's Shine located in their territory to their territory.
