Casinos fail all the time because they as everyone else have fixed cost, and in the Las Vegas style casinos especially because they are not just casinos but massive hotels or resorts where the fixed costs are absolutely huge. There's certainly lots of room for innovation in that area, and in attracting gamblers.
Casinos don't generally fail because they don't know how to tweak the odds.

i'm not talking about keeping what casinos have right now and "tweaking" that. I'm talking about a reimagining.
