How the math works
A $50 bonus bet, hedged to guarantee a return regardless of outcome
Example — $50 Bonus Bet · Lakers vs. Celtics
Promotional bet
Lakers ML
−110 · DraftKings
Stake: $50 bonus bet
Hedge bet
Celtics ML
−110 · FanDuel
Stake: $24.17 cash
Results
If Lakers win
$21.46
If Celtics win
$21.46
Cash required
$24.17
Because the bonus stake is free, the math always produces a positive return on the hedge. The exact figure depends on the odds available at the time.

Common questions
Is matched betting legal?
Yes. Placing hedge bets to manage the outcome of a promotional bet is entirely legal. You are using sportsbook promotions as intended and placing real bets through licensed operators — the same way you might use a credit card sign-up bonus.
What is a bonus bet calculator?
A bonus bet calculator tells you how much to bet on the opposing side (the hedge) and what profit you will lock in across both outcomes. CvilleBets does this for any odds combination.
How much can I extract from sportsbook promos?
A $100 bonus bet typically converts to $55–$75 depending on odds. The exact amount depends on the odds available at the time and how efficiently you hedge. CvilleBets shows you the numbers before you place anything.
What is a no-sweat bet?
A no-sweat bet refunds your stake as a bonus bet if your wager loses. You profit if you win outright; if you lose, the refund bonus bet can be converted using the same hedging approach.
What is a profit boost?
A profit boost increases your payout on a winning bet by a set percentage — for example, a 25% boost on +200 odds pays like +250. CvilleBets calculates the hedge needed to lock in the additional profit the boost creates.
