Types Of Sports Betting Bonuses
Sportsbook bonus offers come in many different forms. You’ll often see the sports betting sites recommended by Props.com rotate through some of the following common bonus offer types:
Bet-Get Bonus
Bet-Get bonuses award bonus betting credits to new players after making their first bet at a given sportsbook.
For instance, FanDuel Sportsbook Massachusetts often offers a Bet $5 Get $150 in Bonus Bets welcome promo. If you’ve never created a FanDuel account, you can sign up as a new player, make your first deposit, and make your first bet (at least $5).
After you make that bet, FanDuel will award $150 in bonus bets. Keep in mind that bonus bets only allow you to keep the winnings from the bet, not the bet itself.
You’ll sometimes see variations on this bonus type such as the following:
- Bet $5 Get $150 if your Bet Wins
- Bet $5 (on any pregame moneyline) Get $150
Be sure to pay attention to the exact wording of a Bet-Get bonus to understand the specific terms.
First Bet Insurance
First bet insurance bonuses cover your first bet at a sportsbook with a refund if the wager loses.
For example, BetMGM Massachusetts often welcomes new players with a $1,500 First Bet Back promo. That offer allows you to make your first wager at BetMGM, and get a rebate on the bet if it loses (up to a $1,500 max).
With that offer in place, you could make your first deposit at BetMGM, and place a $1,500 bet. If that bet loses, you would see $1,500 in bonus bets appear in your account.
The rebate matches the amount of your first bet. So if your first bet was for $500, and it lost, you’d get $500 in bonus bets back.
You’ll see this bonus type often referred to as a “No Sweat First Bet” or a “Paid Back” bonus, among other similar terms.
Deposit Match
The deposit match is one of the most common bonus types you’ll see across all online gaming sites, including sportsbooks, daily fantasy sites, and online casinos.
Many of the DFS apps listed on this website offer deposit matches as a welcome bonus. For instance, Underdog Fantasy generally presents a 100% deposit match up to $100 as a sigup bonus.
Sign up for a Underdog Fantasy account, make your first deposit, and Underdog will match 100% of that deposit up to $100.
The match funds often come in the form of bonus credits. You generally have to meet some kind of playthrough requirement before you can withdraw the bonus funds.
At Underdog, you must play through 1x of your original deposit, plus 1x of the bonus credits, before you can withdraw winnings from the bonus credits.
Much like bonus bets at a sportsbook, bonus credits only allow you to retain the winnings from any entry placed, and not the original stake.
