When it comes to sports betting, you’ll likely have seen the spread, moneyline, and over/under odds. The spread is simply the difference between the teams’ predicted final score. Other types of wagers include futures and teasers. All of these bets are similar in nature. However, they involve different kinds of risk, ranging from high to low. For example, the favorite team may lose by less than the spread, while the underdog could win by more than that.
