These bookmaker offers come in all shapes and sizes. It can be difficult to sift through them all and pick out the most valuable sports betting offers. Fortunately, Bookies has done the hard work for you. Read on to discover the best betting offers from licensed, reputable bookmakers. We will break down what the various sports betting offers entail, how to claim them, and the rollover requirements you must complete before cashing out.

Bookmaker Offers

Bookmaker offers boost your chances of securing a profit when wagering on sports. They allow you to play with house money, so we recommend claiming as many high-quality sports betting promotions as possible.

We set out to find the best bookmaker offers on the market. Our experts signed up for accounts with dozens of legal sportsbooks. They claimed betting welcome offers at each bookmaker to ensure it worked properly. We then compared the various betting sign-up offers against one another.

That allowed us to identify the world's best bookmakers' betting offers. We have listed them below. Bookies only recommends betting promotions from legal, legitimate bookmakers that provide secure payouts and a strong all-around user experience. You can sign up with as many of these sports betting apps as you like, as that will ensure you benefit from multiple welcome bonuses. Here are the best betting offers available right now:

Bookmaker offers can be broadly grouped into two categories: new customer betting offers (also known as welcome bonuses), which are aimed at new customers and can only be claimed once per bookie; and recurring bonuses for existing customers, which can be used on an ongoing basis.

Welcome bonuses are generally larger and more exciting than the betting promotion options existing customers could enjoy. Sportsbooks use sign-up bonuses in a bid to build up market share at the expense of rivals, so they need to be appealing. These are the most common types of sports betting offers aimed at new customers:

Free Bets

Some of the best bookmaker offers provide new customers with free bets. You generally need to place a qualifying wager to unlock the bookmaker's free bet offers.

The flagship welcome bonus from WynnBET is a perfect example. WynnBet offers a "Bet $50, Get $200" sign-up offer. You just need to register an account, deposit $50, and wager it on any sport at odds of at least -120 to qualify.

WynnBET will then give you four $50 free bets. Each free bet offer has a 1x rollover requirement. It must be used on a sporting event at odds of -150 or longer, and any winnings you earn will then go into your cash balance.

Bookmakers such as DraftKings, FanDuel and BetMGM sportsbook provide similar betting sign-up offers on a short-term basis. Recent examples include:

  • Bet $5, Get $100
  • Bet $5, Get $150
  • Bet $10, Get $200

In each case, you simply need to sign up and place a qualifying wager to unlock a series of free bets. For example, DraftKings offer a promotion where you could wager $5 and instantly receive six $25 free bets, each with just a 1x playthrough requirement. It is worth checking the terms and conditions, as some sportsbooks will only give you the free bets if your qualifying wager wins, whereas most give you the free bets regardless of whether the qualifying wager wins, loses or pushes.

No Deposit Bonus

This is a very rare - but very appealing - type of bookmaker bonus. Some betting sites will simply award new customers bonus funds, without requiring a qualifying deposit. As such, these betting sign-up offers are known as free bet no deposit bonuses.

A no-deposit bonus gives you a chance to test-drive a gambling site or mobile app. You can also earn a cash profit if you complete the wagering requirements.

If it is a no-deposit bonus sportsbook, it will typically give you a small amount of site credit - such as $5 or $10 - and you must then complete a large rollover requirement before requesting a withdrawal.

In that time, the sportsbook hopes you will be impressed, enjoy the experience, and return regularly as a long-term customer. However, you are not under any obligation to do so, and you may be able to walk away with a cash profit, without having risked any of your own money.

The most high-profile no-deposit bonus of all time was launched in New York at the start of 2022. Caesars sportsbook gave all new customers a $300 no deposit bonus - along with a 100% deposit match up to $3,000 - when it launched in the Empire State. The $300 had a mere 1x playthrough requirement, so Caesars incurred a heavy loss on that deal in a bid to build market share in New York.

We are unlikely to see any offers so generous in the future, but we will let readers know if any legitimate sportsbooks launch no-deposit bonuses.



Matched Deposit Bonus

This is a common form of bookmaker bonus. It is also very attractive compared to a risk-free bet deal. A deposit match bonus is simple: you sign up and make a minimum deposit, and the sportsbook then matches a percentage of your deposit with bonus funds.

For example, BetRivers offers offers new customers a 100% deposit match of up to $250. DraftKings often runs a 20% deposit match bonus worth up to $1,000.

The bonus funds will be released into your account as soon as you have made your initial deposit. You can normally divide them up and use them however you like. For example, you could place a single $200 bet, or you might decide to place five $40 bets.

When you have completed the stated rollover requirement - which is normally 1x - you can cash out any profits earned. You may need to hit minimum odds when rolling over your deposit match bonus money so check the terms and conditions.

New Customer Offer

This is a catch-all term used to describe the sports betting bonuses that are provided as an incentive to sign up. The most common forms of new customer betting offers are:

You generally need to sign up and make a deposit to qualify for a new customer offer. Some sportsbooks will issue the bonus funds immediately, whereas others require you to place a qualifying bet first.

As the name suggests, this type of bookmaker bonus is restricted to new customers. That means you can only claim one sign-up bonus at each sportsbook - even if the welcome bonus offer changes. When you have registered with a sports betting site and claimed a new customer betting bonus, you will be precluded from all future welcome offers it provides. However, you will benefit from a steady stream of ongoing betting offers, which we have highlighted in the "Existing Customer Betting Offers" section below.

You can also sign up with lots of rival betting apps if you would like to claim a variety of new customer bookmaker offers. That can earn you thousands of dollars in bonus money.

Welcome Offer

A welcome offer is another term used to describe a new customer offer or a sign-up bonus at an online sportsbook. We listed the main types of free bet welcome offers in the section above.

Lots of sportsbooks provide a risk-free bet as their welcome offer. That includes famous names such as BetMGM sportsbook, Caesars, and FanDuel sportsbook. To claim these betting sign-up offers, you must register an account, make a deposit, and place a minimum wager - such as $10 or $20 - on a sporting event of your choice. If your bet wins, you can keep the money and continue betting.

If your first bet loses, you will be issued with a refund up to a certain limit, such as $1,000 or $1,500. Occasionally, a sportsbook will pay the refund in cash, allowing you to withdraw the funds immediately. However, most sportsbooks issue the refund as site credit, with a 1x rollover requirement.

That means you need to play the bonus dollars through once before any winnings earned become eligible for withdrawal. You would need to place a successful bet at odds of +100 or greater to claw back your initial investment.

Another reasonably common welcome offer allows you to place a small wager at boosted odds. For example, the DraftKings sportsbook and Fanduel offer offer before the last Super Bowl was very generous. New customers that registered ahead of the last Super Bowl to wager $5 on either team at odds of +5600. The only difference was that FanDuel sportsbook paid out $280 in cash to anyone that bet on the Rams, whereas DraftKings gave out site credit - seven $40 free bets, each with a 1x playthrough requirement.

Bonus Codes

You may need to use a specific betting bonus codes to claim the best betting sign-up offers at certain online sportsbooks. If that is the case, we will provide you with the codes.

When you find an offer that appeals to you on this page, you can click on the green "CLAIM OFFER" button. That should automatically add the bonus code to the account.

You will be taken through to the betting site, where you can fire up the registration form. You may see a "Promo Code" section on the registration form. The code should be pre-loaded if you clicked a Bookies link. If a code does not appear, you can type it in manually.

Many online sports betting sites do not require a bonus code to claim the best betting promotions. In that case, you can just click on the "CLAIM OFFER" link we have provided, sign up, and complete the necessary steps to redeem the bonus.

Promo Codes

A sportsbook promo code is the same as a bonus code. The terms are used interchangeably in the online sports betting industry.

Some betting sites require the sportsbook promo codes to claim the best new customer offers. We compile all the latest promo codes from elite sportsbooks, so make sure you bookmark this page.

That will ensure you never miss out on an exciting offer. Some of the best betting offers are only available on a short-term basis, so make sure you check in regularly to see what is available.

How to find the Latest Betting Promotions

Bookies is the ultimate source for the latest sports betting promotions from the world's greatest sites and mobile apps. We have our fingers on the pulse, so we never miss high-quality betting offers.

We check in with the best online sportsbooks on a very regular basis to see what betting sign-up offers they are providing. Bookies also maintains contacts with all the leading international betting sites, so they inform us in advance of any exciting sports betting promotions that our readers should know about.

Our experts test each offer to ensure it works correctly. We only recommend attractive betting offers from reputable sportsbooks with low rollover requirements. You can bookmark this page to stay up to date with all the latest betting promotions.

It is also worth regularly checking the "Promotions" page of any sportsbook you have already signed up with. The best operators provide a wide array of ongoing deals for their users, so you will spot plenty of generous betting promotions - particularly ahead of major sporting events, such as the NFL.

What to Look for When Choosing a Betting Offer?

There are three key factors to consider when weighing up the appeal of a betting offer:

  • How much of your own money you need to risk to claim the bonus.
  • The size of the sportsbook bonus and the maximum site credit on offer.
  • The wagering requirements you need to complete before cashing out.

In an ideal world, the best betting offers would require minimal risk to unlock a large amount of site credit, with gentle rollover requirements.

For example, DraftKings sportsbook launched a "Bet $5, Get $150" bonus during the 2022 NBA Finals that appealed massively to NBA betting fans. New customers could sign up, bet $5 on a game and receive six free $25 bets, regardless of whether the $5 qualifying won, lost or pushed. The free bets had just a 1x rollover requirement, and any profits earned were paid in cash, which could immediately be withdrawn. That was an especially appealing offer, as customers only needed to risk $5 to potentially win hundreds of dollars in cash.

Unfortunately, it was only available on a short-term basis, but we should see plenty of similar betting sign-up offers launched in future. We will highlight all the best betting promotions on this page.

What Sports Can I Use Betting Offers On?

Most betting offers can be used on any of the sports covered at a gambling site or mobile app. These are some of the most popular sports that bettors focus on when completing rollover requirements:

  • Football
  • Basketball
  • Baseball
  • Soccer
  • Hockey
  • Golf
  • Tennis
  • MMA
  • Boxing
  • Motorsports

You can also use the best betting offers on a variety of additional sports, including athletics, Aussie Rules, badminton, cricket, cycling, darts, eSports, futsal, handball, lacrosse, pool, softball, snooker, table tennis, volleyball, water polo, and winter sports. Some sites also accept bets on novelty and entertainment markets, depending on where you are based, and you can bet on politics if you’re not using US sports betting sites.

Certain betting sign-up offers and ongoing betting promotions are sport-specific. For example, you may receive an odds boost to use on a soccer match at particular soccer betting sites, a parlay bonus on NBA action or a "bet and get" deal to use on a golf tournament. Those betting offers tend to run on a short-term basis, and they depend upon which sports are currently in season.

Existing Customer Betting Offers

Lots of operators offer sports betting bonuses and promotions to keep existing customers sweet. Unlike betting sign-up offers, these promos can be claimed on a recurring basis. These are some of the most common existing customer betting offers you will find:

  • Free Bets: Some sportsbooks will simply give you free bet deals to use on major sporting events. However, you normally need to place a qualifying wager to unlock the free bet. For example, you may be given a $10 free bet offer as a reward for wagering $20 on a parlay.
  • Parlay Boosts: Lots of sportsbooks boost the winnings you earn on successful parlays. The size of the boost depends upon the number of legs you add. You need to hit minimum odds requirements and add a certain number of legs to qualify.
  • Insurance Deals: You may be offered your money back - typically as a free bet - if one leg of a parlay or same-game parlay lets you down, if the game you bet on goes to overtime if the fight you wager on ends in a draw. These insurance deals may be referred to as money-back specials.
  • Odds Boosts: Several sports betting sites boost the odds on major events taking place each day. The boosts may be applied to standard bets, but they are more commonly available on parlays, prop bets, and same-game parlays.
  • Profit Boosts: Certain sportsbooks issue profit boost tokens. For example, you might get a 20% baseball betting boost on a Tuesday, a 20% tennis boost on a Wednesday, and so on.
  • Contests & Prize Draws: Contests are available at a variety of sportsbooks. You can normally enter for free and then make predictions on sporting events in an effort to finish near the top of the leaderboard and win free bet credits. Other sportsbooks offer prize draws, handing out tickets to sporting events, memorabilia, and so on.
  • Loyalty Programs: Rewards programs are available at many betting sites. You earn points by placing wagers. They stack up in your account, and you can ultimately redeem them for free bets.

Sports Betting Offers Terms and Conditions

There will be terms and conditions underneath all the best betting promotions. They explain who qualifies for the bonus, how to claim it and the requirements you must complete before you cash out a profit. These are the key terms to consider on sports betting offers:

  • Minimum Deposit: A minimum deposit is required to redeem most betting sign-up offers. It varies from one sportsbook to the next.
  • Minimum Bet: You may also need to place a minimum bet to qualify. That is the case on a risk-free bet bonus, an odds boost bonus, a matched first bet or a "bet and get" deal.
  • Maximum Bonus Funds: Betting account offers come with an upper limit, such as $250, $500 or $1,000. For example, if you claim a 100% deposit match bonus up to $250, and you make a $400 deposit, you will only receive $250 in bonus funds.
  • Rollover Requirements: This explains how many times you need to turn the site credit over before withdrawing any winnings. For example, if you have a $200 bonus with a 1x rollover, you need to place $200 worth of bets before withdrawing. If you have a $200 bonus with a 3x rollover, you need to place $600 worth of wagers.
  • Minimum Odds: There may be minimum odds requirements on certain sports betting promotions. They can apply to your qualifying bet and/or the bonus funds.
  • Wagering Restrictions: You may be prevented from using your bonus funds on certain bet types or sports. You cannot use the early cashout feature either.
  • Time Limits: Any bonus funds you receive will expire on a certain date. Make sure you complete the wagering requirements before that date, or the credits will be forfeited and removed from your account.

Frequently Asked Questions

What is a bookmaker offer?

Bookmaker offers provide potential customers with incentives to sign up with an online sportsbook. The best betting sign-up offers include deposit match bonuses, free bets, and huge odds boosts. Gambling sites also provide betting offers for existing customers to encourage them to place more wagers and dissuade them from taking their business elsewhere.

How to get the latest sports betting offers

Bookies have rounded up the most exciting betting sign-up offers from legal, trusted online sportsbooks. You can bookmark our betting offers page and return on a regular basis to find all the latest betting site offers and sports betting promotions. We provide readers with any promo codes necessary to unlock the best bookmaker offers.

How do bookmaker offers work?

You normally need to make a minimum deposit to claim the best sports betting offers. Some sportsbooks match your first deposit amount immediately with bonus funds, while others require you to place a qualifying wager. The concept tends to be the same: risk some of your own money to unlock bonus funds and complete wagering requirements before cashing out.

Can you cash out a bookmaker betting offer?

You cannot use the early cash out feature on any bonus credits received from betting site offers. It is a helpful feature, as it allows you to end a live bet before the game finishes, but it could easily be manipulated by anyone trying to complete rollover requirements. You must let bonus bets run until the end of any contest.

Are bookmaker offers worth it?

The best bookmaker offers are always worth claiming. If you find a large sign-up offer or ongoing sportsbook promotions that come with a 1x playthrough requirement, we recommend taking advantage of it. The only betting offers to avoid are those that tie you down to unrealistic rollover requirements.

Are there restrictions on sports betting offers?

There will be restrictions on many betting special offers and betting promotions. For example, you may need to make a minimum deposit to qualify, and you must then complete rollover requirements. There could be minimum odds requirements, and sportsbooks may restrict the types of wagers you can place. So, check the terms and conditions.

How do betting bonuses work?

You will find betting offers for new customers, which can only be used once per sportsbook, along with recurring sports betting promotions aimed at existing customers. Examples include free bets, deposit match bonuses, odds boosts, and profit boosts. You normally need to place bets with your own money to qualify and complete the wagering requirements on the bonus funds.

What are the best types of betting sign up offers?

A deposit match bonus and large “bet and get” deals tend to be the best betting sign-up offers. A deposit match bonus with a 1x playthrough requirement is very appealing. Offers such as “Bet $5, Get $200” and “Bet $10, Get $200” from operators like DraftKings and FanDuel are also highly attractive.
