What is a bookmakers welcome bonus?
Before we go any further, it is of course necessary to understand what are the welcome bonuses that are offered by sports betting sites.
It goes without saying that more and more sports betting sites are present on the market every day. From Bet365 to William Hill, 1xbet to BetOBet, Vbet or Melbet, there are a variety of operators that offers internet users the opportunity to place their sports bets online - each of which has their own unique qualities, as well as some small areas of improvement.
Such a significant number of bookmakers inevitably creates an air of competition to attract sports betting fans, which is where welcome bonuses play an important role.
Coming in many different kinds and forms; these welcome bonuses offered by bookmakers are advantages promised to lovers of sports betting - an incentive to open an account with these well-known bookmakers.
In short, it is the bookmakers way of saying "Register with us to bet, we offer you such advantages when you sign up". Similar to many other aspects of daily life, these actions reminds us of establishments such as banks and supermarkets with their constant promotions.
In the end, the real winner remains to be you, the bettor, as you will be able to enjoy the numerous sign-up offers of these betting sites as new customers, particularly by registering with multiple betting sites.
Obviously, just because you register with Bet365 and get a bonus doesn't mean that you can't open an account at vbet and collect another welcome offer.
In the end, all the sports betting bonuses on the market are available to you, allowing you to benefit from huge advantages before placing your bets. It's up to you to take advantage of them, and that's why we've listed the most attractive welcome bonuses above, which you should grab now.
Whether it's an offer on your first deposit, cash back or free bets: never miss out on a welcome bonus, whatever its nature. The amount of the bonus doesn't really matter either - you have everything to gain by getting it in any case. What's more, registration on betting sites takes just a few minutes.
What are the different types of bonuses at online betting sites in 2025?
Although over time bookmakers have gradually standardized their various bookie sign up offers, know that these famous sports betting bonuses take different forms, and vary in generosity. Here are the most common bonuses that we find in July 2025 on the market of online bookmakers. Don't miss them - they'll help you make a smooth start in sports betting.
First deposit match bonus
The first deposit match bonus is the most common form of welcome offer to new customers today. This bonus works in a way that the first amount of money that you deposit into your player account will have an influence on the amount that will be offered by the bookmaker.
Generally, the value of your welcome bonus will be 100% of the deposit you pay. For example, if you deposit $100 in your account after you register for the first time at this bookmaker, you can expect to receive a $100 after you active the account. You will ended up with $200 to play with when you start your sports betting at this betting site.
As generous as it is, you have to read carefully the T&Cs to obtain the full amount bonus, and there is always a cap to the maximum amount of bonus you can get.
Money back offer
A money back offer, can also be called as first-bet refund bonus or refunded bets. According to our specialists, this is the best bonus for new customers. Often not requiring any real condition to be withdrawn, a money back offer will, as its name suggests, refund your stake if your first bet is not a winning one.
For example, you bet $100 on Liverpool to win against Arsenal in your first bet, but the Reds take a draw at the Emirates? You will then be refunded the amount of your bet in full, and you can then withdraw the $100 from your account (if no other specific condition is dictated by the operator).
Free bets
Another popular form of bonus is free bets, or bet credits, which are very commonly offered by sportsbooks to new customers. There are mainly two kinds of free bets on the market.
Free bets when your first bet lost
The first kind is refund free bets, or "risk free first bet". As with the money back offer, this free bet bonus involves the bookmaker paying back the stake of your first sports bet if you lose it.
However, the difference between this refund and the money back offer is that the refund of free bets normally cannot be withdrawn. After your first bet with your deposit money is lost, the bookmaker refunds this money to your account as bet credits (or free bets as some call it), but you must use it on the same betting site. Sometimes it requires a sports betting promo code to benefit from free bets.
Free bets on your first qualifying bet
The second kind of free bets from sportsbook is free bets on the first bet. It comes often with a form of "Bet £10 Get £10" (Vbet UK), or "Bet £10 Get £50 in free bets" (bet365). It means after you deposit and place the first qualifying bet, the bookmaker will give a certain amount of free bets (or bet credits) into your account.
In this case, a qualifying bet must be placed before new customers online benefit from this free bet offer. A qualifying bet must meet certain conditions, such as a time limit for placing the first bet after signing up, wagering requirements and minimum odds. After this bet is settled, the free bets will be automatically credit to your account for you to play with.
Same as the other forms of free bets, this bonus is not cash refund and therefore cannot be withdrawn. They are bet credits that must be used in the same betting site, usually with a time limit as well but highly possible without any wagering requirements. If your next bets, using free bets as stake, are winners, the profit you made from it is directly for you to cash out, though the free bets stake will not be refunded to your account.
As you can see, bonuses and new customer offers in different forms can be very different even with similar names. Therefore, we encourage you to always read the terms and conditions provided by the bookmaker before using this free bet - or any other bookmaker offers and bonuses. It is still a generous type of bonus and widely appreciated by punters.
No Deposit Bonus: Is there really such thing?
Contrary to the situation which existed a few years ago, bonuses that do not require any payment beforehand no longer exist on the sports betting market. Although some special promotions come up from time to time, no deposit bonuses seem to be very rare among bookmakers these days, much to our regret. Although we are hoping that some betting sites will prove us wrong in the future; bookmaker bonuses of this type no longer exist on the major sports betting markets such as the UK, mainly because their lack of efficiency was noted by bookmakers.
Can anyone get a bonus?
All punters can get a welcome bonus as long as they meet certain conditions. Here are the most common:
- Over the legal gambling age in your country
- Living in the territory where the bookmaker is authorised to offer its service
- Opening an account with the bookmaker for the first time
- Not be on the list of people banned from gambling
- Comply with the conditions set by the operator (odds, minimum stake, etc.)
Whether we're talking about the Bet365 free bets, 1xbet welcome offer or a bonus offered by any other operator, every new player who meets these requirements can get their sports betting bonus. Good news for sports betting fans.
Do not register with Unlicensed Bookmakers
It is important for us to remind you not to register with a site that does not hold a license. Being licensed means that if there are problems, they will be investigated and sanctioned accordingly. Safety at online sites is always important and the holding of a license that has been granted by a regulatory body is just what you want to see. In the UK, it's the UK Gambling Commission. In Nigeria, it's the National Lottery Regulatory Commission. And in South Africa, it's Western Cape Gambling and Racing Board.
A bookmaker, whether online betting sites or physical stores, must comply with local laws and meet certain conditions to be granted that license. Therefore, a licensed bookmaker will not want to do anything that might see them lose it. Joining an unlicensed site means there is no protection for you when disputes occur.
A bonus goes unpaid? Profits to which you are legally entitled to never enter your account? Your personal data has been hacked or leaked? In this situation, there will be nothing you can do if you register with an un licensed bookmaker. Which is why, as experts in the world of online betting, we strongly advise that you avoid unlicensed sites, even if they offer tempting bonuses. It may well be that the bonus offered has so many restrictions it is difficult to withdraw anything anyway. In any case, there are plenty of opportunities available with the best licensed bookmakers on the market - why look anywhere else?
