Rollbit is not a new site, If you search rollbit on youtube you can check that some gambling streamer / youtuber has been promoting them since last year. I've found a video that was 11 months old about rollbit, some older dates video probably exist as well but back then it seems Rollbit only has those csgo skins type of roulette but now the site is packed with 3rd party slots already
Yes, this one is already a year old and have some YT vids which are already 8months.

Additional slot games could really make some difference?
