New mobile game called “Word Relax!” Is it legit?

I like playing word games on my phone. I downloaded this one and incidentally discovered that I’m apparently accruing real money that I can “cash out” into PayPal once I reach $20.

I checked the version history and found that the very first version was released about 2 weeks ago (in the Apple App Store, anyway).

Figured I should ask you guys about it and see if anyone else has discovered and used it. Is it for real?
