A free bet is the one edge a sportsbook hands you on purpose, and most people torch it in about 30 seconds by slapping it on a heavy favorite. I've claimed dozens of these offers across DraftKings 🎁, FanDuel 🎁, BetMGM 🎁, and Caesars, and the gap between a good promo and a trap almost always comes down to a few lines of fine print nobody reads. The best free bet offers are not the ones with the biggest headline number, they are the ones you can actually convert to cash. Here is how I size up any free bet promo before I claim it, and how I hedge the good ones so the game's result barely matters and most of the token turns into withdrawable cash.
TL;DR
- The Headline Dollar Amount Is The Least Useful Number. Judge a free bet offer on any odds restrictions, its expiry window, and whether winnings pay as withdrawable cash or replay-only site credit.
- A $100 Bonus Bet Is Not Worth $100. You keep the winnings but never the stake, so the token is only worth what you can convert it to.
- Convert It, Don't Gamble It. Place the free bet at long odds, hedge the other side at a second book, and a clean fill keeps you roughly 60¢ to 83¢ on the dollar depending on the odds, whichever side wins.

What A Free Bet Actually Is (And Why $100 Isn't $100)
"Free bet," "bonus bet," and "bet credit" all mean the same thing: a token the book gives you to wager with, where you keep the winnings but not the stake. That last part is the whole story.
Say you get a $100 free bet and put it on a team at +200. If it wins, the book pays you $200 in profit and keeps the $100 token. A real $100 cash bet at +200 would have returned $300 (your $100 back plus $200). So the stake never comes back, which means a $100 bonus bet is worth clearly less than $100 in cash. Knowing that number is what separates people who extract real value from people who just gamble the credit away.
The practical takeaways fall out of that one rule:
- The Stake Is Gone Whether You Win Or Lose, so a losing free bet costs you nothing and a winning one only pays the profit.
- Longer Odds Keep More Of The Value (more on the math below), which is the opposite of how most bettors instinctively use a bonus.
- A Free Bet Is Only "Worth" What You Can Realistically Convert It To, not its face value.
What Makes A Free Bet Offer Good
Not every promo is worth your time or a deposit. When I evaluate a free bet offer, I run down the same short checklist. The face amount is the least important part.
| Factor | Green flag | Red flag |
|---|---|---|
| Size And Structure | One larger token, or a "bet $5, get $150" bet-and-get | Tiny credits, or a big number split into many small tokens |
| Odds Restrictions | No cap on how long you can bet the token | A max-odds cap, or a rule that blocks the long-odds placement conversion needs |
| Expiry Window | 7 days or more | 24 to 72 hours, easy to forget and lose |
| Winnings Paid As | Cash you can withdraw | Site credit that must be replayed |
| Wagering / Playthrough | None (true bonus bet) | 1x to 10x rollover before you can cash out |
| Book Availability | Live and legal in your state | Not offered where you bet |
The three that quietly kill value are odds restrictions, expiry, and cash-versus-credit. A generous $200 promo that caps the odds you can use it at, expires in a day, and pays winnings as replay-only credit is worse than a clean $50 bonus bet you can convert at long odds and withdraw. Read those three lines before the dollar figure.
Rule of thumb: the dollar figure is the least important number in a free bet offer. Any odds restriction, the expiry window, and whether winnings come back as withdrawable cash decide what the promo is actually worth.
The Main Types Of Free Bet Promos
Most sportsbook offers fall into a handful of categories. They market them with fresh names constantly, but the mechanics rarely change.
- Sign-Up Bonus Bets (Bet-And-Get). The dominant welcome offer today: "bet $5, get $150 in bonus bets." You risk a small real wager, and the site drops bonus bets in your account win or lose. DraftKings and FanDuel both call these "bonus bets," while bet365 labels them "bet credits." The name changes book to book; the stake-not-returned mechanic does not.
- Deposit Match. The book matches a percentage of your first deposit in bonus funds. These usually carry playthrough (you must wager the bonus a set number of times before withdrawal), so read the rollover before you get excited about the headline number.
- Bonus-Bets-Back / Second-Chance. If your first qualifying bet loses, the book refunds it as a bonus bet. This is the modern version of the old first-bet-refund promos. You still lose the cash if it loses; you just get a bonus token back.
- Reload And Existing-User Promos. Odds boosts, profit boosts, parlay insurance, and periodic bonus-bet drops for players who already have an account. Boosts are not free bets, but they add promo value in the same spirit, and a big enough boost can flip a bet in your favor.
- Refer-A-Friend. You and the friend can both get bonus bets once they sign up and place a qualifying bet. Low effort, real value. One note on scope: this guide covers traditional sportsbook free bets. Prediction-market exchanges like Kalshi run their own sign-up incentives, but those are deposit or trading credits with different mechanics, so they sit outside the conversion math below. Fantasy pick'em apps sit in their own lane too: the Sleeper fantasy football promo code, for example, pays out as play-through contest credit with its own claim rules and strategy.
How To Squeeze Maximum Value From Any Free Bet
Because the stake never comes back, the goal is not "win the free bet." The goal is to convert as much of that face value into real, withdrawable cash as possible, no matter which side of the game hits.
The move is straightforward: place the free bet on a longer-odds outcome, then place a normal cash bet on the other side (the hedge) at another book. Done right, and assuming both bets get accepted at the prices you need, you come away with about the same profit whether your free bet wins or loses. That is exactly what our How to convert a free bet guide walks through step by step, and it is the entire job of the OddsShopper Free Bet Converter.
The reason longer odds matter is the conversion rate. The figures below are the net cash you hold after hedging the free bet at a fair price, expressed per $1 of the token, and they land about the same whether the free bet wins or loses:
| Free Bet Odds | Decimal | Net cash per $1, after a fair hedge |
|---|---|---|
| +150 | 2.50 | ~60¢ |
| +200 | 3.00 | ~67¢ |
| +250 | 3.50 | ~71¢ |
| +300 | 4.00 | ~75¢ |
| +500 | 6.00 | ~83¢ |
The pattern is the point: the longer the odds you place the free bet at, the more of it you keep. Put it on a -300 favorite and you convert roughly 25 cents on the dollar. Put it on a +300 underdog and hedge cleanly, and you keep about 75 cents. Real hedges give a little back to the book's vig, which is why line shopping the hedge matters, and it is why I run every conversion through a free bet calculator rather than eyeballing it.
There is a second route the sharps use: instead of hedging to cash, ride the bonus bet on a real +EV parlay at long odds, where the de-vig fair odds say the true probability beats the price offered. OddsShopper's Portfolio EV tool finds those spots by stripping the book's hold out of every line to expose the real number, so you are not guessing at which long shot is actually priced in your favor. That route swings for more upside and accepts more variance. Converting to cash is the lower-variance play; the +EV parlay is the aggressive one. Either beats burning the token on a short favorite.
In practice that collapses into a workflow you can run the moment a token hits your account. You drop in the free bet amount and the book it came from, and the tool surfaces the spot that converts the most for the book and state you are in; it then scans every major sportsbook for the tightest hedge on the other side and shows you the hedge stake and the projected net cash for each outcome. The math the last two sections worked through becomes a ten-second check, which is the whole point of building the conversion habit into how you claim offers rather than treating it as a one-off.

A Real Example: Turning A $100 Bonus Bet Into Cash
Here is one I ran recently, with round numbers so the mechanics are clear. I had a $100 bonus bet and put it on an underdog at +250. Then I went to a different book and bet the other side at -270 to hedge.
- Hedge Stake: about $182 on the -270 side.
- If The Free Bet Wins: I collect $250 in profit from the token and lose the $182 hedge, netting about $68.
- If The Free Bet Loses: the token cost me nothing, and the $182 hedge wins about $68, netting about $68.
Either way I come away with roughly $68 of real, withdrawable cash from a $100 bonus bet, which is about a 68% conversion. That is the whole game: the outcome of the match stops mattering, and the free bet becomes cash. Shop the hedge line at the best available price and that number climbs; take a lazy hedge and it drops.
Mistakes That Waste A Free Bet
The offers are only as good as how you use them. The ways I see people leak value:
- Burning It On A Big Favorite. A bonus bet on a -300 chalk keeps roughly a quarter of its value. Save the token for longer odds.
- Letting It Expire. Short windows are the most common way value evaporates. Note the expiry the moment it hits your account.
- Skipping The Hedge Shop. The hedge price decides your conversion. Taking the first number you see instead of the best one gives cents back to the book on every conversion.
- Chasing A Deposit-Match Rollover. A match with 10x playthrough at a forced minimum odds can be worth far less than the headline. Do the math before you deposit.
- Forgetting To Toggle The Token On The Slip. If you do not actually select the bonus bet, most books quietly stake your real cash instead, and the promo just sits in the account unused.
- Using It On A Market You Cannot Hedge. A same-game parlay or a longshot with no clean opposite side at another book cannot be converted, so the token's value stays welded to the result.
A word on account health: books do watch for pattern behavior, and heavy, mechanical promo hunting can draw limits over time. Keep your betting varied and normal, treat conversions as one part of your approach rather than your entire play, and you are simply using offers the way they were advertised. None of this is a get-rich scheme; it is a disciplined way to get the most from money the book chose to give you.

Frequently Asked Questions
What is the best type of free bet offer? A clean bonus bet with no odds restrictions, a week or more to use it, and winnings paid as withdrawable cash. Those beat a bigger promo loaded with playthrough, a short expiry, or odds limits that block the long-odds plays conversion needs.
What is a good free bet conversion rate? Around 70% or better is a strong result. The rate depends almost entirely on the odds you place the token at: fair-price conversion runs about 60% at +150 and climbs past 80% at +500.
What odds should I use a free bet on? Longer odds, generally +200 or higher, because the stake is not returned. Placing a bonus bet on a short favorite throws most of its value away.
What is the difference between a free bet and a bonus bet? Nothing meaningful. "Free bet," "bonus bet," and "bet credit" are interchangeable names for a token where you keep the winnings but not the stake. US books mostly say "bonus bets" now.
Can you withdraw a free bet directly? No. The token itself cannot be cashed out, and you never get the stake back. You have to convert it by winning the wager, ideally with a hedge that turns it into withdrawable cash.
Do free bets expire? Almost always. Windows range from about 24 hours to several weeks, so check the expiry the moment the credit posts and plan to use it well before the deadline.
Is converting a free bet legal? Yes. Hedging your own bets across legal, regulated sportsbooks is legal and standard bettor behavior. Individual books can still limit accounts or restrict heavy promo play under their own terms, so you are working within their rules, not around the law.
Will using free bets get my account limited? It can over time if your activity looks purely mechanical. Keeping your overall betting varied and normal, rather than only ever grinding promos, keeps your account healthier.

The Bottom Line
The best free bet offers are the clean ones: no forced minimum odds, a comfortable expiry, and winnings you can withdraw. Once you have a good token, the value is not in winning the bet, it is in converting it. Place it at longer odds, hedge the other side at the best available price, and you turn the book's promo into real cash regardless of the result. Do that on every offer and the promos stop being a novelty and start being a steady, disciplined part of your edge.
