Flipsies.io is on polygon

If you have metamask or a polygon wallet, i highly suggest you checking out flipsies.io, ive never played a poker game like it online

THEY HAVE A WEB VERSION - + A MOBILE VERSION

Honestly, doesn't seem like a casino to me:

"Flipsies offers an online gambling experience. You must be over 18 years old to click on any gambling related activities on Flipsies.

Flipsies- will not be held responsible for any violation of local laws enforced in your region. Flipsies games are based on fairness, transparency and fun.

Care to explain how it works?
