Most people who want to place bets on sports are fans to begin with. It isn’t unheard of for a gambler to place some sports bets, especially during big games like the Super Bowl or the NCAA basketball Final Four, but for the most part, sports bettors are sports fans looking to use their knowledge of a game or of a game’s players to earn a little extra cash. Being a fan of a particular sport, a team, a college or professional squad—these are all precursors to placing sports bet. Sports betting is also a way for a fan to get in on the action of the game, with something more than self-respect at stake.
All gambling is mathematics, even games of chance. If you understand the math behind the game, you understand the game and can give yourself an advantage. For many games, like penny slots or poorly placed roulette bets, are so bad that smart bettors earn their advantage by avoiding them altogether. In sports betting, the math is more complicated. Depending on your favorite sport, you may need to think about things like bye weeks, underdogs, quarterback ratings, and injuries with the same fervor other connoisseurs reserve for fancy winces.
So how difficult is sports betting math? The math behind placing a winning bet is fairly complicated, but the way to stay ahead of the bookmaker is rather straightforward. If you collect on 52.4% of your bets, you’ll break even. We’ll have more details on that number later, including why it takes more than 50% wins to break even, but first some general knowledge about sports gambling and the numbers behind it.
