Can I use a bonus to bet on corners?

The answer depends on your sportsbook. Most online sportsbooks give away free bets to their new players but they usually come with some conditions. For instance, you might be asked to place those bets on odds higher than 1.80. And some sportsbooks might even limit the betting options you can use for free bets. As a result, you might not be able to use the bonus funds for corner betting.
