Yeah, that's a different website from the source I shared on my original post. Not sure where you got the "aviamasters.com/free-demo". If you run the URL link Cointxz shared or the one you can get on the demo play on the source I shared, it will show 0/97 on VirusTotal.
I thought as much seeing how the interface looks like makes me feels like it is a demo and not real aviator.
They look differently from the original aviator build these gambling site I do comes across, it doesn't look attractive for someone to join playing the game, and based on what op said one can't cashout until the plan lands on its own.
