While I hate playing in a crowded casino too the fact is that you may be able to win.I mean if a lot of people are playing at a certain slot and they all end up with losing a lot of money if you play right after them chances are that the machine will give back some money and you may be a lucky winner.This theory is not proved though and is just a gamble itself.
If some one wants to enjoy the game and require the peace, then this is not the place where they could enjoy it. And someone just want to make money and if they consider it as a lucky then crowd will not matter much to them till the time they can make money.
The casino cannot stop people from coming as so we can’t force casino to stop players to play just to give us privacy
Or if we really want to be private and peace?the play online lol
