It was discussed there but it wasn't thoroughly discussed, unlike this one. Maybe this could change what was previously there. It might be local and a niche but I think there is potential as I think gamblers are really looking into alternatives to what card games we know today.

It would be most likely played by less than 5% (probably less) of gamblers? This topic was discussed before and has never been that popular.
Vast majority of people just commented that this game is complicated and they have no intention of finding out what this game is about.
Why create tongits or pusoy variants when we don't have that many well established bitcoin poker sites?
