Most new users will receive the $1,500 first bet opportunity, so let’s go through how to redeem this offer first.
You can bet up to $1,500 on any game and get your stake back in a bonus refund if your bet loses. As an example, if you bet $1,000 on the Phillies to beat the Reds at Citizens Bank Park, you can secure a large payout if your bet wins. If your bet loses, you will get your $1,000 stake refunded in the form of a bonus to use later on.
If you receive the $150 bonus offer, you must win your initial $10 bet to get the reward. Make sure to pick a market that you believe is likely to settle as a win, whether it is a simple moneyline wager or a prop bet.
Bonuses you receive with either offer will expire after one week.
