Cassino is essentially
gambling. The engineers who project those machines are specialists on probability theory and its application to games of chance. There's science on it. Ok, there's a little margin of skill on the Black Jack, but not much.
All the apparatus are made to take much more than give as the owners must pay their taxes, employees, free drinks etc. When somebody wins, the management eager to spread the notice, highlight them just to attract more players, like a bait to fish them.
But the cassino environment is wonderful though, course it should be. Is part of the business.
You may find a poker room inside a good cassino, but poker, you know, it's another story.
