The words casino imply gaming house, by definition and that means a public place where all people can gather and play games with cash, also called slot machines. Gambling has been legal in Nevada since 1980, and Las Vegas casinos were opening everywhere in the years that followed. In Las Vegas, as in many areas around the country, the game of casino is largely looked down upon by the vast majority of society. Even though it is legal, it is widely considered to be bad luck. A good deal of folks are always trying to avoid gambling at any cost, but the truth is that casinos are a great way to enjoy yourself when you're on vacation.
