1. Parimatch – Bet and Get Free Bets Offer

Here are some of the leading candidates in 2026. - As bettors who like to wager on a range of sports, the BetMGM betting sign up offer was perfect for us, allowing us to choose which market we redeemed our free bets on. Whereas some offers restrict you to wagering on specific sports or events, we were able to use our bets where we wanted to and decided to split the free bets across football and rugby league Another aspect of the offer we liked is that the free bets are broken into 4 x £10 bets. It made it easy for us to separate our betting funds between betting on the Champions League and having a separate bet on the Challenge Cup. In total we received 2 x £10 bets that we used on different sports, and also 2 x £10 bet builders.

Deposit £40, Get a £20 Free Bet

It's always more of a challenge to pick winning selections in a bet builder, so having a free bet allowed us to be a bit riskier and include some selections with longer odds. As long as the odds were greater than 3/1 we were free to include bets from different markets. The fact that BetMGM rewards players with 400% x their first wager is a brilliant incentive to join. But the flexibility in the bonus really helped us become familiar with the site, testing betting bonuses on different sports, and we've wagered at BetMGM on a regular basis since playing through the promotion.

During our testing we looked into how to trigger the offer, checking the qualifying criteria and minimum odds before placing our initial £40 stake on Man City vs Crystal Palace in the Premier League. There were numerous markets available that we typically bet on that would also trigger the bonus. Once the bet had settled, the £20 in free bets was credited to our account, which we decided to split rather than using it in one go, placing a portion on a horse racing market and bet no deposit bonus no wagering requirements used the remaining free bet on a football bet.

This suited our betting strategy at a new site by ensuring we didn't need to wager a huge amount to trigger the bonus. After our qualifying bet had settled, the £10 free bet was credited to our account automatically. We used it on a separate rugby league selection, although there were plenty of other betting markets available across football, horse racing, tennis and more. During our testing, the whole process felt smooth and straightforward, with no unnecessary steps to redeem the bonus. We particularly liked that the offer gives new customers a risk free opportunity to explore the sportsbook and try different betting markets.

There are plenty of competitors so rewarding those who continue to bet with them is a key consideration for online brands.

How we do it?

Not every online betting offer feature free bets, but they are almost universally accepted as the main type of betting bonus at the moment. A free bet bonus could be as part of a welcome package, like Bet365's Bet £10 and get £30 in bet credits offer, or as a loyalty offer. You can see more about this specific bonus in our bet365 review. In 2026, this type of betting site welcome offers is often used as a loyalty promotion. For example, bet £10 on the Champions League final and get another £10 free bet to use.

These type of offers can be good value because if the original bet wins, you also have the free bet to utilise, if the original bet loses, the free bet could prove successful and make up for it. Not a lot of online bookmakers will have No Deposit Free Bets available for new customers. They are popular when they are used, but some bookmakers think it is too risky. No deposit free bets will see punters receive free bets or free spins on the casino side of the site without the need of depositing any money. Yes, they are rare and the payout is not massive but the punters love it because they are getting a go on the betting site without spending a penny. Free bets, profit boosts and competitions where bonuses can be won are all popular approaches in 2026.

There's certainly more to the world of placing wagers online than just online betting welcome offers.

The attention around specific events often prompts betting sites to offer specific free bets or bonuses around them. For example you can find World Cup betting offers, bonuses on racing events or the Super Bowl.

Popular Types of Sports Betting Bonuses

Let's get something clear, being a new customer at an online betting site is likely to be one of the most advantageous positions in terms of free bets offers. Sign up bonuses and welcome offers are a key tool for the majority of online bookmakers to attract new players and get them to sign up. In sports betting it's often free bets, bet 100 free bets when you sign up whereas the best online casino sites usually have free spins available. That's why the value of welcome bonuses is often higher than you'd expect as an existing customer, so it pays to keep an eye on the marketplace. For the purposes of our explanations, we're going to cover the various types of bonus separately to fully explain how they work. Bookmakers know that the interest in these type of events is high, so could choose to offer specific promotions around it.

Keep your eyes peeled for the latest betting deals.

If you're going to be betting on these events then getting an additional bonus or free bet for doing so adds extra value to the equation.

Terms and Conditions of Free Bet Offers

– During our testing, the Betnero welcome offer was straightforward and easy to use. By placing a £10 qualifying bet, we received a £10 free bet that could be used on a wide range of sports markets. What stood out most was the simplicity of the promotion. We placed our qualifying bet on football and then used the free bet on a separate boxing selection, which allowed us to try different markets while exploring the sportsbook. We weren't as familiar with Betnero as some of the more established sites so offers like this are ideal for us because they allow us to get to know the site and its betting features.

What Could Be Better?

We liked the flexible wagering options and the fact we didn't need to deposit a large amount to receive a bonus. If you're looking for a new customer bonus but aren't sure about some of the newer brands, our bonus test confirms that the Betnero promotion is well worth considering. Play responsibly 1st deposit only Min deposit €10 Qualifying bet: min €10, on any acca or bet builder (2+ selections) with min odds 6/4 (2/5) on selected sports €10 free bet: 2+ leg acca or bet builder (2+ selections), min odds 6/4. Why we like the Bet365 bet 100 free bets no deposit uk welcome offer? – We really liked the bet £10 & get £30 promotion, especially compared to other sportsbook welcome offers that have various restrictions in place.

Referral Bonus

To redeem the offer, we first checked the qualifying criteria, then placed a £10 bet on a Premier League match that we were interested in anyway, but having a risk free bet was a good option. Once that initial bet had been settled, the £30 in free bets were credited to our account, split into three separate £10 bonuses. This allowed us to spread our free bet credits rather than using everything on one selection, and redeemed a bonus on a horse racing market, another on a tennis match, and used the final bonus bet on a football acca. Overall, we found the process simple and liked the structure of the bonus terms. If any punters are looking to redeem a deal, the Bet365 sportsbook welcome offer is worth trying. Getting a matched bet bonus was a popular new customer approach a few years ago, but less so these days.

The premise is that if you bet a certain amount, the betting site in question will match that stake - usually as a free bet.
