This ranking is interesting. Yeet Casino is quite new and has already made it into the top 16... and I must admit I didn't expect Roobet to be second, but that's because I stopped playing there a long time ago.
I won't really fancy this ranking system because I can't really tell what data was used to compile these averages and how accurate those data were and as a result how accurate the compilation is. There are many ways casinos run ads , and this community or forum rather, just happens to be one of them.
Considering this some casinos could rank over others in certain advertisement niches and because if that you can't outrightly say that they have same position in an overall consideration of niches.
