Claw Machine - Gambling?

I was just wondering, why isn’t the claw machine considered gambling?

I would say not legally, as it can be construed as an opportunity to get something through physical skill.

Ugh, sorry, there is a new topic on this post exactly. I did a search, but didn’t find it. Sorry, you may delete this thread.
