Matched Betting
What is the "Matched Betting Value" listed above? This is the amount of profit that you can make from the sign-up offer through a technique called matched betting. In short, it is a mathematical approach to sports betting that guarantees profit by hedging your bets. This allows you to cover all possible outcomes and secure a profit no matter what happens in the game. This is different from gambling because there is no risk of losing.

MLB House Rules
Each sportsbook has its own House Rules which determine how a bet is graded. These rules cover unlikely events, such as what happens to your bet when a game is canceled.
Usually, the different house rules across sportsbooks do not have an impact on matched betting. However, in Major League Baseball (MLB), there are notable exceptions. A simple example is when a game is postponed due to weather. Read our House Rules Comparison guide to learn more.
For MLB it is also important to understand what defines Action.
