If you still think you can take on the casinos, here are the Ten Things the Gaming Industry Won't Tell You by SmartMoney - for example:
1. "You can't win..."
Everyone knows the house has an advantage. But most casino patrons don't realize just how heavily the odds are stacked against them. Take keno, in which you pick a string of numbers, hoping to match them to what the casino randomly generates. The house advantage is at least 25%, increasing with the more numbers you pick, says John Alcamo, author of Casino Gambling Behind the Tables. The odds of hitting, say, the 10 spot — a string of 10 numbers — are nine million to one. (Getting killed by fireworks is nine times more likely.) Despite those odds, a $2 bet usually pays off at only $50,000 to $200,000.
Slot machines are popular because they offer a shot at a big jackpot for little investment. For example, $3 gets you a chance at the Megabucks jackpot, which links slot machines in Nevada and builds like a state lottery from a base of $5 million. The odds of winning? Nearly 17 million to one. You have a better chance of being killed by an asteroid striking Earth.
