I can't remember when last i visited the site through my pc, so I can't say for sure, but just as you have said, accessing the site and passing the cloud flare human checker is pretty easy on mobile, over here on my side, I most of the time don't even have to select any images as a means of verification, the cloudflare verifies on its own immediately I click on the box..

Concerning passing the verification on pc, I did suggest you maybe try it with a different network, that is, use a different ISP if you have a access to multiple options, I believe this should work, this Is if it's a must or very important you access the casino on pc though, if not, then just stick with mobile.
