Let’s start with the $150 bonus offer, as that has the important caveat that you must win your initial $10 bet.
With this offer, make sure that you look at a wide variety of betting options and find one that you think is likely to settle as a win. Once you find a bet you are comfortable, place it and wait for it to settle to see if you win the $150 in bonus bets.
With the $1,500 first bet safety net, you can wager up to that amount and get your stake refunded if your bet loses. So, an $800 bet on the Phillies could net you a huge win, but you will also receive an $800 bonus refund if your bet loses.
Use any bonus bets you receive with either offer within one week before they expire from your account.
