In order to use this sports betting strategy, you need to place two bets: (1) the free bet on one side of a two-way market (such as a spread, total, or moneyline bet), (2) a cash wager on the other side of the same market.
While you won't win as much as you would if you only bet the free play and won, you will always win some money with this strategy.
Using the top section of our Free Bet Calculator will show you how much to wager in order to maximize your guaranteed profit. You can use the bottom section to see how much you would win if you wager a different amount than the top section suggests. In the second case, you could win more or less depending on the result of your free bet and other wager.
This strategy is also called free bet conversion. The idea is that you can convert some percent of that free bet amount into guaranteed winnings by betting the other side with another sportsbook. Typically, a free bet conversion of 70% or more is considered good. The tool above an also be used as a free bet conversion calculator or risk-free bet calculator.
