After you've spent some time on the slot machines, move on to the Blackjack table, and start by just observing. Blackjack has the best odds of winning, with a house edge of just 1 percent in most casinos, Bean said. Plus, you are playing against only the dealer, not hooded poker champions.

It's all a matter of chance. There are no blackjack- or video poker-like strategies that can cut into the house's mathematical edge. Odds on slot machines are unchanging. There's nothing you can do legally that will change the outcome, though scam artists sometimes have succeeded until caught, arrested and imprisoned.
