• > Entering the requested information when prompted.
• > Submitting a first-time deposit (usually of a specified amount).
• > If necessary, placing a first-time wager (also of a certain amount) on the Dodgers vs. Cubs or any other valid market.

Follow these general steps, and you should have unlocked your sportsbook promo of choice. Note that steps may vary depending on the sportsbook, and that the full terms and conditions of these deals can be found by clicking any of our site links.

Sportsbook promos are not exclusive, meaning users can redeem deals at as many sportsbooks as they wish. 

The offers mentioned above, though, are only available for new customers. However, returning customers will find a variety of recurring offers such as:
