If you're willing to put in a little work, blackjack offers the best odds. I'm talking about a . 5 percent casino edge, depending on which table you're sitting at. (Meaning for every dollar you gamble, you'll lose only half a penny on average.)

At its core, sports betting is putting money behind an outcome of your choice and getting paid if that outcome is achieved. If a bet is on the winner of a game, that is called a moneyline bet. If you're betting that a team will win or lose by a certain amount of points, that is called a spread bet.
