Sports Betting Bonuses
Sports betting bonuses are promotional incentives offered by sports betting operators to attract new players and encourage bettors to place wagers and bets. In the sports betting realm, they are divided into 9 categories:
-
Cash signup bonuses
-
Free bets bonuses
-
Money back bonuses
-
Welcome bonuses
-
Matched deposit bonuses
-
Enhanced odds
-
Mobile sports betting bonuses
-
Cashback bonuses

Cash Signup Bonuses Cash signup bonuses are a type of promotion where the sportsbook offers new players a cash reward when they create an account and make an initial deposit. Keep in mind that the cash reward is given in the form of a percentage match of the deposit amount and comes with a specified limit.
Free Bets Bonuses Free bets bonuses are a type of bonus where players are provided with a complimentary bet or betting credit, allowing them to place a wager without risking their own money. This bonus comes in many variants and the most popular are:
-
Risk-free bets
-
Deposit X amount and get X amount bets
-
No deposit free bets
-
Free bets signup offers
With a risk-free bet, you get your bet stake refunded if your bet loses. The Deposit X amount and get X amount back variant is a common one, and it entails making a deposit and getting an already set amount of free bet. A common example is Bet €20 and get €50. A no deposit free bet doesn't require players to make a deposit to take advantage of this bonus.
Money Back Bonuses
A money back bonus is a type of bonus where the sportsbook refunds lost stakes if a specified trigger occurs. The lost stakes are typically refunded as cash or free bets and other incentives. This type of bonus allows players to wager their money without fear of losing it.
Welcome Bonuses
Welcome bonuses are a promotional offer designed to attract new players and involve giving players bonus money when signing up and making their first deposit. Each operator has a different bonus with different percentages and money amounts, such as 100% up to €100. Some operators include bonus spins in their welcome offer. These bonuses come in the form of free bets, cash sign up, and other incentives.
Matched Deposit Bonuses
Matched deposit bonuses are offered by a sports betting site where the bookmaker will match your first deposit up to a specified amount. This type of bonus effectively increases the amount of money available for betting and comes with specified terms and conditions.
Enhanced Odds
Enhanced odds are a type of promotion where the sports betting site offers players higher than usual betting odds on a specific event or outcome. This bonus is typically available for a limited time and is also known as price boosts or odds boosts.
Mobile Sports Betting Bonuses
Mobile sports betting bonuses are promotions that are tailored for players who place bets via their mobile phones. These bonuses are exclusive to mobile users to encourage mobile betting.
Cashback Bonuses
Cashback bonuses are promotions where punters get a certain percentage of their losses back. If you experience losses while betting, a cashback bonus can provide a partial refund.
ACCA Booster Bonuses
ACCA booster bonuses are offered by sports betting sites that help boost your winnings from accumulator bets. If you place a successful accumulator bet with an ACCA booster, your payout will be higher than if you had bet without the booster.
