Will there ever be a blindfolded category for single fights?

Probably not. Blindfolded runs would require cam, but even with that it is really difficult to track cheating. People could simply use blindfolds that does not actually hinder their view.

But what if they simply look away from the screen with a blindfold?

I just Tryed Contender With A Hat As a Blindfold

how'd you do?

I beat it

The one i'd be afraid of is soda pop. That's why I haven't tried it yet. But TD Mr. Sandman is actually not that bad.

I actually beat contender Bald Bull Blindfolded recently, Currently practicing Contender Soda Pop

Ye I did the circuits blindfolded in separate videos on my channel but you could barely see my face
