For starters, if you feel like you're playing with bonus money, you may not be inclined to put much thought into your bets. There are positives and negatives to bonus bets. The idea is that sportsbooks will get new people to sign up for accounts and deposit money, and if they win a few bets, maybe continue wagering at that sportsbook instead of going elsewhere. Almost every sportsbook has some kind of deal to attract new bettors and there are many different methods to draw people in. First, you have to deposit at least $5 into your account and then you'll get the $20 in bonus play money, which is not redeemable for cash. For instance, DraftKings used to have a $20 bonus play that has a number of stipulations. Most bonus bets are only available on a first deposit at that specific sportsbook. Bonus bets in sports betting are often connected to deposits and are also referred to as bonuses.
