If you receive the $150 bonus offer, make sure to place your initial $10 bet on a market that you believe is likely to settle as a win.
If you plan on betting on an MLB game, you might want to look at some player props for one of Sunday’s games, whether it is a strikeout bet or a bet on a player to record a hit. This type of bet might be easier to get right than predicting the winner of a game. You could also bet on a player to finish in a certain position in the U.S. Open.
If you get the $1,500 first bet offer, you can wager up to that amount on any market, and if you lose, you will get that stake back. Let’s say you want to put $1,000 on a U.S. Open market. If your bet wins, you will get a large cash payout. If your bet loses, you will get that $1,000 stake back in the form of a bonus.
