The Betting Bonus At a First Glance
A bonus sports bet is a reward you can receive often, but not always, as part of a welcome bonus offer. As per the UKGC, the promotion is popular among bettors of 44 or younger with more than 51% expressing a positive attitude towards such offers.
The free bet is usually valid for a limited event or events. It comes in a specified monetary value. For example, $5, $10, $25 bonus sports bet, etc. The most common range for this type of offer is $5-$200.
It’s important to make a distinction between a free bet and free money. A free sports bet bonus gives you a chance to win money, but you have to put in some effort. We support the opinion of the player below. There are no completely risk-free betting offers.

How does it work?
A free bet offer is usually available when you register at betting sites with a sign up bonus. Other promotions require you to make a qualifying deposit. The exact amount is different at each sportsbook, but it is often between $5 and $30. Some sports betting sign-up bonus offers can be claimed with a simple registration and without a minimum deposit.
Expert Tip:
Look for bonus bets with a low wagering requirement of less than 35x.
The Four Main Types of Betting Bonuses
Depending on the triggering and conversion conditions, there are four main betting bonus types. We describe them below.
Welcome sports bonus
As the most common betting reward, the welcome offer is ideal for site exploration and taking the edge of your first bet. Such promotions can range from $5 to $200, with wagering requirements ranging from 0x to 40x. They are usually valid for the most popular sports. Some sites even offer an e-sport bonus for new players.
The Hotline Casino sportsbook bonus, for example, offers a 100% sign up bonus for sports betting. The minimum deposit is just €10, which is an excellent way to start.
Pros:
- A chance to try a sportsbook;
- A chance to win real money with little to no investment;
- Usually, it comes with additional bonuses.
Cons:
- Requires you to create a sportsbook account.
Who is it best suited for?—New bettors.
Deposit match
Deposit match betting bonuses are a second layer of rewards at betting sites with a welcome bonus. Such setups offer regular rewards for your deposits with a match of 50%, 100%, or 150% in free bonus bets. The great advantage of this type is that you can use it for sports events that you wouldn’t normally bet on, and thus expand your knowledge and skillset, plus get a chance to win real money. Of course, deposit match bets come with a minimum deposit requirement (from $10 to $30) and wagering requirements (from 5x to 40x).
Pros:
- Reward further investment into sportsbooks;
- A chance to learn about unusual sport events or leagues;
- Minimum deposit requirement to trigger them is usually low and affordable.
Cons:
- Most offers are rollover-tied.

Free bet
Free bets are usually given upon sign-up or as a reward for making a bet with your own money. Generally, the word ‘free’ refers to the triggering condition of this promotion. It is different from a no wager bonus sports bet in that it still has wagering conditions. A free bet can range from $5 to $200 in value and will usually be valid for pre-selected events with a certain rollover (from 5x to 40x).
Pros:
- Most commonly comes as a sports betting no deposit bonus;
- Excellent for testing a sportsbook;
- Little to no risk involved.
Cons:
- Usually comes with higher odds requirements.
Who is it best suited for?—Active bettors.
Bet insurance
Insurances are a much-desired safety net for your bets. This type of sports betting free bonus promises a return in free wagers if you lose a couple of games from an accumulator bet, for example. While the value is usually not high, between $5 and $25, this opens the door for strategies which involve more risk. For example, betting on at least two fixtures in the acca selection with odds over 300.
Pros:
- This sports betting bonus is Ideal for beginners;
- Excellent for taking calculated risks within an accumulator bet;
- Makes a win dead-certain;
- Available as a no-deposit sports bonus on some sites.
Cons:
- The sum of the free insurance bet is usually not high.
Who is it best suited for?—Beginners.
How to Claim Sports Betting Bonuses: Step-by-step Guide
The ways you can claim a betting offer vary depending on the conditions decided by the different sportsbooks. You can find the specific steps at the site that offers the promotion. Here, we will provide you with a general outline of how you can trigger most offers.
Step 1 – Consider betting promotions
Start with finding the best possible bonus offers. Larger sports betting bonuses are not always better. The best ones offer easy conversion containing low to no wagering requirements and supported events with low odds. Consider carefully how useful a bonus will be to you.
Step 2 – Pick and register on a good sportsbook
Next, check the security characteristics and reputation of the sportsbook that offers the bonus. We recommend that you play at licenced sites from our lists, which we have rigorously tested ourselves.
Tip: Use sites with credentials from MGA, Curacao, Kahnawake, Alderney, as well as those authorised by US states.
Step 3 – Understand the terms and conditions
The T&Cs of your chosen betting sign-up bonus contain the rollover and the minimum deposit you will use to trigger Play according to the rules and use strategies like arbitraging, and bagging sparingly to ensure successful conversion.
Step 4 – Make a qualifying deposit or trigger the activation conditions
Most betting bonuses can be unlocked with a minimum deposit. But, some, like the free bet, ask you to simply create a sportsbook account. The triggering conditions are described on the home page of the bonus or in the T&Cs. Sometimes, you will need to use betting bonus codes.
Step 5 – Place a bet and meet the requirements
With the free bet bonus activated, start placing wagers on events with qualifying odds. Avoid using elaborate strategies and bet as simply as possible. The winnings from your bonus bet will be available to bet again until you meet the full rollover requirements or until they run out.
Tip: Bonus progression will be shown from your profile section. Sometimes, the required sum you have to wager will be shown after you make a deposit at the sportsbook.
The Four Key Criteria to Choose The Best Betting Bonus
Our specialists have tested over a thousand sportsbook promos in best online casinos. Below, we will share with you the most important points you should consider when choosing promotions of this type.
- Bonus Size: Generally, the more, the better, but this is not always the deciding factor, as bonus value is often calculated on how easy it is to convert.
- Wagering Rules: The value of sports betting welcome bonus depends on the size and the supported odds. For instance, a $10 bet on odds -500 may be worth more than a $50 bet on odds 900. Consider the winning chances of the promotion.
- Retrigger Option: The option to retrigger a betting bonus adds value, but, of course, it should be considered alongside other factors, such as wagering conditions, personal budget, etc. For example, a betting offer of $20 with a minimum deposit of $20 every Tuesday may be valuable if you are willing to spend that amount of money every week.
- Maximum Winnings Cap: Bonuses with higher winning caps are usually more valuable. However, considerations should also be given to other important factors, such as the wagering requirements.
Expert Tip:
Consider each factor in the context of all others. See how they interact with each other and what the overall value is for your style of betting.
Betting requirements for Sports Bet Free Bonus
A good bonus is a combination of acceptable wagering requirements which provide realistic chances of winning money. What exactly is considered favourable? Below, we delve deeper into each rule.
Rollover/play-through
This is hugely important because the less a sports bonus has to be wagered, the quicker and easier to turn it into cash. To get the real value, compare the rollover with the bonus size. With lower value bonuses, higher rollovers are acceptable, but with free bets over $100, play-throughs higher than 35x (the market average) become difficult for most players. Generally, we advise you to look for values between 1x and 40x for low-amount bonuses and 1-25x for high-amount ones.

Maximum bet
Consider this. You have to reach $250 wagered stakes, but your max wager is just $1. You have to make at least 50-60 bets to get to the cap. Now consider the difference. You have to wager $250 but your bet cap is $10. The maximum bet rule defines how bright a bonus burns because with larger bets you win quicker, but you may also lose the bonus quicker. With smaller bets, you play with less risk but for longer.
Minimum deposit
How a bonus is triggered is important, too. Even though most promotions of this type have a minimum deposit requirement of $5 to $100, the most valuable ones are without a top-up rule. By using an automatic calculator to calculate the value of a bonus and including your betting budget in your estimation, you can make accurate decisions about whether to commit a minimum deposit to trigger a sports bet bonus.
Country restrictions
We pick the best sportsbook promo codes that are valid for North American countries. If you access our lists from elsewhere, it might be worth checking the T&Cs to find out whether a bonus is supported for your country.
Expert Tip:
Check for country restrictions for the sports betting free bonus specifically.
