I reckon with the collective knowledge on this forum if everyone came together it'd be easy to make a room that'd blow people out the water. Casinos especially cause that's the only place you can really show off stacking and get away with it but if you think about it today's casinos are nothing compared to what they could be. The most I've seen is basic flat roller stacking around the edge of the room, not on petals of course.
But most people ITT could, if they thought hard enough, make a casino bringing new stuff to the plate that the majority of people on habbo don't even have a clue about (don't mean to patronize but it's true). I'm talking bar stacking, inside merged 2+ space gates, on petals everywhere, flat and then cram some hcs or t sofas in there somewhere too. And that's just the bare minimum - you could add anything, within reason, to the stacks with total ease and with Verrou's new item you could do it all without giving any clues as to how it's done or compromising how furni is meant to look (e.g flat on the floor). Hell, we spent a good week and a half wearing one possible theory down to nothing. It's an open market far as I'm concerned and I'd love to see someone swoop in with a casino that totally puts everyone else's to shame.
