Here you'll find a list of all the obstacles that are known to be in Ball Race. Obstacles are just one element of the puzzles to Ball Race. They can be your friend or enemy based on how you use them.

First Appeared In: Sky World
Crate
A simple box that weights quite a bit and can be hard to push. Can be spawned from above.
First Appeared In: Grass World
Bumpers
These are everyone's friend. Once you collide with them, they fire you back based on your velocity. Even the slightest touch can send you into a frenzy of bumper hell.
First Appeared In: Grass World
Rocks
Falling rocks from above. Tricky to get past as they can knock your ball right off course.
First Appeared In: Grass World
Chemicals
A nasty pool of chemicals just ready to burst your orb. Stay clear away from this toxic goo or you'll be wasted trash.
First Appeared In: Memories
Repeller
A magnetic repeller that pushes your orb away from itself. Useful to jump with, but be careful as they can deal more of a push than a normal bumper.
First Appeared In: Memories
Attractor
Just like the repeller, this is a magnetic pole. However these will pull your orb towards themselves. Be careful as if you get too close to their pole - you'll pop.
First Appeared In: Memories
Magical Block
These invisible blocks will only appear when you get near them. Can be quite the tricky devils when you're low on time.
First Appeared In: Paradise
Explosive Crate
Just like a normal crate, only slightly more explosive.
First Appeared In: Khromidro
Windmill
A windmill haiku: Round and round it spins/Gusts of wind will make you fall/Do not become sad
To Appear In: Metal World
Black Goo
Black goo left behind by the unfriendly Ball Race god to annoy you. Once you roll over this your orb will move slowly until its effect as weared off.
