Only make bets that have a casino advantage of 2 percent or less. It's a green felt jungle out there. Here are two illustrations. Casino management knows the average Joe and Josephine do not play through their money just once, but keep playing their slot machine tray over and over again during the course of their stay. The casino is grinding away at your hard-earned money.
Casinos sometimes advertise selected machines that offer a higher payback percentage.
When you get to the casino, you'll need to ask someone working in the slot area which machines those are. Here's the other example. In craps, a pass line bet, with no odds, has a house advantage of 1.4 percent. Relatively cheap entertainment. In comparison, the hard six or eight wager on a craps game has a house advantage of 9.1 percent.
