The first wall every beginner hits is opening the account, seeing a bonus balance, and discovering the withdraw button does nothing for it. That is not a bug or a trick. Bonus bets are built so that they can only be used to bet, and the way people get real money out of them is by converting them. This post explains what that means and works one example from start to finish.
Read this first
Conversion uses your own cash on the other side of the bonus bet. If the two placements are mistimed, mispriced, or one is voided, you can lose real money. Nothing about this is guaranteed.
The Short Answer: No, Not Directly
You cannot withdraw a bonus bet. You can only place it. If the bet wins, the winnings are cash and can be withdrawn subject to the book's terms. If it loses, the credit is simply gone. Everything else in this post is about making that first outcome matter less.
The bonus balance is separate from the cash balance on purpose, and the withdraw button only reads cash. Every book, offshore or regulated, works this way, because the point of a bonus bet is to make you place a bet.
The rule, as most books' terms put it: bonus bets have no cash value, cannot be withdrawn, cannot be exchanged, and must be wagered in full on a single bet. Winnings from a bonus bet are paid as cash, excluding the bonus stake. Unused bonus bets expire. Some offshore books attach a rollover to the winnings as well, so read the actual clause.
Offshore sportsbooks carry no US regulatory backstop. If an offshore book refuses to pay the winnings from a converted bonus bet, or holds the withdrawal indefinitely, there is no state regulator to appeal to. Your options are the book's support desk and public pressure. This site's guide to platforms that will not pay shows the escalation ladder that exists for US-based platforms, and most of those rungs are missing for an offshore book. Whether you can legally bet with one is unsettled and varies by state: federal law has historically targeted operators rather than individual bettors, most states do not criminalize the individual bettor, and a small number have statutes that arguably do. Check your own state. 21+. Check what is legal where you are.
What a Bonus Bet Actually Is
A bonus bet is a stake the book lends you for one wager. It sits in a separate balance, usually expires, often carries minimum odds, and cannot be split, cashed out, or moved. Some books call it a free bet, a bonus token, or a bet credit. The mechanics are the same.
| What the book calls it | What it is |
|---|---|
| Bonus bet, bet credit, bonus token | The regulated-book names. A credit you place once, stake not returned. |
| Free bet, free play, free play bonus | The offshore-book names at Bovada, BetOnline, MyBookie, and others. Same thing, sometimes with a rollover on the winnings. |
Three restrictions apply almost everywhere.
- Expiry. Seven days is common at regulated books, offshore windows vary more. An expired credit is removed, not extended.
- Minimum odds. Often 1.50 to 1.80 decimal, to stop you dumping the credit on a heavy favourite where the cover would be almost free.
- Single use. The whole credit goes on one ticket, no splitting, and usually no early cash out.
Stake Not Returned, and Why It Matters
When a cash bet wins, you get your stake back plus the profit. When a bonus bet wins, you get only the profit. That one difference is why bonus bets are worth less than their face value and why longer odds tend to convert better than short ones.
| Outcome | $50 cash bet at 3.00 decimal (+200) | $50 bonus bet at 3.00 decimal (+200) |
|---|---|---|
| If it wins | $150 returned: your $50 stake plus $100 winnings | $100 returned: winnings only, the $50 credit is consumed |
| If it loses | $50 of your cash gone | The credit is gone, no cash lost |
| What a win is worth | Stake plus profit | Profit only |
That missing stake is why longer odds convert better. At 3.00 the bonus bet returns two thirds of what a cash bet would, at 1.50 one third, at 6.00 five sixths. The longer the price, the smaller the share the missing stake represents, which is why conversion is usually done at 4.00 or longer, as long as a close cover exists.
How Conversion Works
You place the bonus bet on one outcome and place a cash bet on the opposite outcome somewhere else. Whichever side wins, one ticket pays. The cash you keep is a portion of the bonus, not all of it, because the cover bet costs money. The portion you keep is the conversion rate.
First placement: the bonus bet at Book A on the longer price. Second: a cash bet at Book B on the opposite outcome, sized so the cash you hold after settlement is about the same whichever side wins. Place the bonus bet first, because it cannot be changed, then size the cover from the price you actually see at Book B.
The conversion rate is the cash left after both tickets settle, divided by the bonus bet's face value. In words: what the bonus ticket would pay if it won, minus what the cover would lose, compared to the bonus amount. Longer odds and closer prices push it up. Wide margins and minimum-odds rules push it down.
The cover stake is the number people get wrong by hand, and getting it wrong turns a conversion into a coin flip. Disclosure: Online Sidehustles works with the BreadSync and BookMethods team, and this is a partner link. BreadSync includes a free bet converter that takes the bonus amount and both prices and returns the cover stake. Its free tier, no card required, covers bet tracking with auto-grading, bankroll management, a dashboard, live scores, win probability, and calculators. Pro is $197 a month with a 7 day free trial and adds the odds screen across 90+ sportsbooks. Its supported books list includes Bovada, BetOnline, MyBookie, BetUS, and Everygame. A spreadsheet with one formula does the same arithmetic for one offer, so run a few by hand first.
A Worked Example, Both Sides
This is the whole post in one table. Two books, one bonus bet, one cash cover bet, and what you hold after settlement in both outcomes. If you can follow this once, you can follow every offer that comes after it.
Bovada holds the bonus bet and BetOnline the cover, both common first accounts on the supported list of the tool above. Round numbers, illustrative mechanics only, not a result, and not the prices you will see.
| Step | Book A: Bovada | Book B: BetOnline |
|---|---|---|
| Market | Underdog moneyline at 4.00 decimal (+300) | Favourite moneyline at 1.30 decimal |
| Ticket | $50 bonus bet on the underdog | $115 cash on the favourite |
| If the underdog wins | Ticket pays $150 cash. The $50 credit is consumed. | Ticket loses. $115 gone. |
| If the favourite wins | Ticket loses. The credit is gone, no cash lost. | Ticket pays $149.50 including the $115 stake. |
Read the two outcome rows together. In one, cash arrives at Bovada and leaves BetOnline. In the other, cash stays at BetOnline with a little added. The amounts land close to each other, which is the point: the game decided which book holds the cash, not how much of the credit became cash. The share of the $50 that survived is the conversion rate, well under face value, because the $115 cover cost real money.
Terms that would void this example
Minimum odds: a 4.00 price clears a 1.80 minimum, a favourite would not. Market exclusions: props, futures, and same-game parlays are often ineligible. Expiry: place the bonus bet inside its window or it vanishes. Void rules: on a postponement one book may void and refund while the other holds the ticket, and a voided bonus bet usually comes back as a bonus bet, not cash. Rollover on winnings: some offshore free plays require the $150 to be wagered again before withdrawal, which adds a second cover and cuts the conversion further.
What Lowers Your Conversion Rate
The gap between the odds at the two books, the book's built-in margin, minimum odds rules that push you into worse markets, and placing the second bet late after the line has moved all cut into what you keep. Most of the skill in this activity is keeping those four things small.
The gap between the two prices
Underdog at 4.00 and favourite at 1.30 imply a combined probability a little over 100 percent, and that excess is what the cover costs you. If Book B only offers 1.25, the gap widens, the cover stake goes up, and the share you keep goes down. Shopping for the closest pair is most of the skill.
The book's margin
Every market is priced so the book keeps a slice, small on mainstream sides and totals, large on props, obscure leagues, and parlays. A bonus bet forced onto a high-margin market converts worse than the same credit on an NFL moneyline.
Minimum odds that push you into worse markets
A minimum-odds rule bites when the only markets that clear it have a poor cover price at Book B, leaving you a choice between a bad pair and an unusable credit.
Placing the cover late
Lines move on injury news, weather, and money. Come back to a favourite at 1.22 instead of 1.30 and your cover stake is larger and your conversion smaller.
Line movement between placements
Both books open, both slips built, cover stake calculated before you confirm the bonus bet. Confirm the bonus bet, then the cover within a minute or two. If the price has moved, recalculate, and if the pair is now poor, accept a worse conversion rather than leaving the bonus bet uncovered. An uncovered bonus bet is a straight gamble on the underdog.
How This Compares to Sweeps Coins Playthrough
If you have cleared a sweeps bonus, you already understand the idea that a credit has strings attached. Playthrough on sweeps is one-sided: you wager through the requirement against the house. Bonus conversion is two-sided: you cover the other outcome yourself. Same instinct, different mechanics.
| Question | Sweeps Coins playthrough | Bonus bet conversion |
|---|---|---|
| Who is on the other side | The house, with a fixed edge | A second book, at whatever price it offers |
| What you risk | The bonus, never your cash | Your cash cover, on every conversion |
| What the requirement is | Wager the credit a set number of times | Place it once, cover it elsewhere |
| What decides the result | Slot variance against the edge | The gap between two prices, and your timing |
| Who to appeal to if it does not pay | Support, BBB, state attorney general | Support only. No US regulator. |
The playthrough guide covers the one-sided version in detail. The two-sided version is this post, and the matched betting hub puts it in the context of a full offer.
Frequently Asked Questions
Short answers to the questions readers ask most about this topic. Each one is expanded on in the sections above.
No. A bonus bet can only be staked. If the bet wins, the winnings are cash and can be withdrawn subject to the book's terms. If it loses, the credit is gone.
Because the stake is not returned on a win and because covering the other side costs money. What you keep after conversion is a portion of the face value, never all of it.
Almost always. Expiry windows vary by book and by promotion, and an expired bonus bet is simply removed from your balance. Check the expiry before you plan around it.
There is no US regulator to appeal to. Offshore sportsbooks operate outside state licensing, so your options are the book's support desk and public pressure. Keep balances at any one offshore book small enough that a refused withdrawal hurts but does not ruin you.
