American (-110, +250) or decimal odds — hedge stake, locked profit & conversion % in seconds
Pair a free bet at Book A with a cash hedge on the opposite side at Book B. Size the hedge right and you lock the same cash whether the bonus wins or the hedge wins.
Bonus wins pay profit only—the stake stays with the book. That changes hedge math. Enter amount and both legs; get hedge stake, locked profit, and conversion % in your odds format.
Enter American moneyline (-110, +250), decimal (2.10), or fractional (11/10). Placeholders follow your Options format; American lines with +/− always work.
Enter bonus amount and both odds — hedge stake, profit, and conversion % update when you calculate.
Place both wagers within a few minutes of each other to reduce line-movement risk.
Place bonus bet of $0.00 at odds 0.00
Place hedge bet of $0.00 at odds 0.00
Guaranteed profit of $0.00 regardless of outcome
| Bet Type | Bet Amount | Odds | If bonus bet wins | If hedge bet wins |
|---|---|---|---|---|
| Bonus Bet | $100 | 2.10 | Win = $110 | Lose = $0 |
| Hedge Bet | $66 | 1.67 | Lose = -$66 | Win = +$44 |
| Net Profit | — | — | $44 | $44 |
Conversion Result: Regardless of outcome, ~$44 guaranteed cash (44% conversion). Hedge stake rounded from $65.87 to $66 for whole-dollar betting.
Shop these before you post. Tighter prices between the two legs mean higher conversion % on the same promo.
Bonus Amount: Free bet credit provided by the platform
Bonus Odds: Odds for placing the bonus bet
Hedge Odds: Opposite odds used to hedge the bonus
Expected Conversion Rate: 70% or higher
Example: $100 bonus → at least $70 withdrawable cash
Find Close Odds: Smaller odds difference between bonus and hedge bets results in higher conversion rate
Choose Main Markets: Use liquid markets like moneylines with fewer restrictions
Low Vig Hedge: Reduce bookmaker vig (juice/margin) on the hedge book—tighter lines improve conversion %
Check Bet Limits: Ensure bet amounts are within allowed limits
Check Bonus Terms: Avoid conditions that prevent cashout
Place both bets quickly: Post the free bet and hedge within minutes—line moves between books can shrink conversion or break the lock.
Bonus wins typically do not return stake, only winnings
Confirm both bookmakers allow the respective bet amounts
Bonus usage conditions may restrict market types or minimum odds
Best strategy is to hedge across different bookmakers to reduce risk
Watch for palpable errors: books may void obviously wrong lines and break your hedge—see FAQ below.
Book A — place the free/bonus bet. Book B — stake real cash on the opposite outcome. Equal-profit sizing means the same net cash whether the bonus leg or hedge leg wins.
| Step | Book A (bonus) | Book B (hedge) |
|---|---|---|
| 1 | Free bet at posted odds | — |
| 2 | — | Cash stake on opposite side |
| Result | Same guaranteed profit either way | |
Let B = bonus amount, Oᵦ = decimal odds on the bonus leg, Oₕ = decimal odds on the hedge. If the bonus wins, cash in = B·(Oᵦ − 1) (stake not returned). If the hedge wins, cash in = H·(Oₕ − 1) minus stake H. Set profits equal and solve: hedge stake H = B·(Oᵦ − 1) / Oₕ.
Guaranteed profit = B·(Oᵦ − 1) − H. Conversion rate % = profit ÷ B × 100. Closer prices (smaller gap between Oᵦ and Oₕ) usually yield higher conversion—pros often target 70–80% on large free bets when lines are tight on liquid moneylines.
With bonus decimal \(O_b\), hedge decimal \(O_h\), and bonus amount \(B\):
Conversion rate \(=\dfrac{(O_b-1)(O_h-1)}{O_h}\times 100\%\) when using the standard equal-profit hedge.
Scenario: $100 free bet at +110 (decimal 2.10) on Team A Over; hedge Under at −150 (decimal 1.67) at another book.
| Step | Value | Note |
|---|---|---|
| Bonus win (no stake back) | $110 | 100 × (2.10 − 1) |
| Hedge stake H | $66 | ≈ $66 at 1.67 decimal |
Bonus win = 100 × (2.10 − 1) = $110. Hedge H = 110 / 1.67 ≈ $66. Guaranteed profit ≈ $44 either way → 44% conversion.
Conversion rate = locked profit ÷ bonus amount. It tracks how close your two prices are—not game luck. On a $100 free bet, 70% means about $70 withdrawable cash locked in.
Rule of thumb: on a main-market moneyline, if conversion % is under 65%, shop another hedge book or wait for a tighter line before posting. Pros on large promos often target 70–80% when lines are tight.
Use conversion % as a go/no-go signal after you enter live odds:
Conversion rate depends on how close the two prices are. On a $100 free bet, 70% conversion means ~$70 withdrawable cash locked in. Tight lines on NFL/NBA moneylines often reach 70–80%; long-shot bonus legs with poor hedge prices may fall to 40–50%.
Always read promo terms: minimum odds, eligible markets, expiration, and whether hedging the same account is restricted. Use separate books when possible and confirm bet limits before posting.
Compare hedge prices and test arbitrage-style locks when books disagree—sometimes a middle beats thin conversion.

After locking cash, size discretionary plays with the expected value calculator—bonus conversion is bankroll prep, not a substitute for +EV discipline.
Size the hedge with equal-profit math, shop tight lines, and verify limits on both books. Conversion is a bankroll tool—not a license to chase losses. Adults 18+ only; never bet money you cannot afford to lose.
18+ only (21+ in some US states). Promotional betting still involves risk on hedge stakes. Set deposit and time limits; never chase losses with bigger hedges.
