Any #grammar folk here?

Bearing in mind I am British English, -- and this is my frame of reference for my question -- what's with the following construct?

"How Does This Even Work?"

It's the word "even" here which I find superfluous and odd. Had it been me, I would have said:

"How Does This Work?"

"Even" is unnecessary, adds nothing, and seems superfluous.

Can anyone explain even why to me, how or why, even, etc, why or even how we even have this? ;)
