Blacklisted Sports Betting Sites
Not all betting sites are worth your time and money. If we think a site could pose a risk to a bettor, we put it on our blacklist. This could be for a few reasons, such as lack of legitimate licensing, poor customer support, suspension of accounts with no explanation, or other suspicious practices. Take caution if you find yourself on any of the betting sites below.
- Bettors have reported issues withdrawing funds
- Poor customer support
- Have been known to withhold winnings
- Failure to respond to complaints
- Reports of accounts being suspended with no explanation
- Payout process can be extremely slow
What is a Free Bet?
A free bet is a bonus offer that allows you to place a wager without paying the stake. Online sportsbooks will typically offer free bets to new users as a way for them to familiarize themselves with the site or app. In many ways, you can think of a free bet as an opportunity to place a wager with a reduced risk as you’re not contributing the stake yourself.
How We Rate the Best Free Bet Offers
Casino.org has a comprehensive process for rating free bet offers. Our team of experts follow multiple steps and examine each deal from numerous perspectives. Below are the features that we look at when reviewing and ranking the best free bet offers.
Naturally, bettors want as large a free bet amount as possible. Here we’ll be looking out for how generous a sportsbook is with their bonus. We’ll also check if the amount can be split over multiple wagers or if it must be used on one single selection.
Typically, a sportsbook will have wagering requirements attached to a free bet that will need to be fulfilled in order for a user to withdraw their winnings. We’ll be looking at the T&Cs of each offer to assess how fair these requirements are for the user. Low or non-existent wagering requirements will score the highest points.
Some free bets will have restrictions on the minimum odds that they can be used on. Here we’ll be looking for sportsbooks that allow free bets to be used on low odds as well as high odds. Typically, most sportsbooks will have qualifying odds of 1.5 (1/2) or greater – this is what we’ll be using as our benchmark.
Once a user’s account has been credited with a free bet, there’ll likely be a validity period to use the bet by. Generous expiry periods let customers take their time and use a bonus bet when it’s right for them. For this reason, we’ll be giving top marks to the sportsbooks that have large free bet validity periods.
Banking & Payout
When reviewing the best free bet offers, we’ll also be looking out for a range of withdrawal methods. We’d expect to see a good range of valid debit or credit cards, e-Wallet and bank transfer options too. Then we’ll be assessing the payout speed to ensure bettors aren’t ever left waiting for their winnings.
Safety & Customer Support
We’ll only recommended sportsbooks that are of the highest standards. In every review we carry out a background check that covers the licensing and certification of each site. Then we’ll be looking out for their range of customer support options to ensure they have their users at the heart of what they do.
Approval & Rating
After carefully analyzing all of the mentioned factors, our experts will rate the sportsbook and its bonus offer. The best free bet bonuses will be added to our shortlist. Rest assured our rankings are updated frequently to ensure that you’re getting the best deal possible.View our recommended free bets
Free Bets & Sports Bonus Types
Take it from us, not all free bet offers are the same. Explore the different sports bonuses below and find out what a sports betting site might have to offer.
- Bonus Description
- First Deposit Bonus
This is a hugely common bonus that’s used to reward new players for registering with a sports betting site. Typically, users will make their first deposit which will then be matched by up to 50-200%. First deposit bonuses are often valid to use on all bets, though can also be applied to specific events like for football or cricket. This bonus type works in the same way as a standard casino bonus.
- Deposit Matched Bet Bonus
This bonus matches a bettor’s first deposit with a free bet of the same value. Bonuses can often be matched up to $100 and can be used right after registration. If used wisely, this bonus type can double the amount a user has to bet with. Just be aware of any minimum deposit or wagering requirements attached.
- No Deposit Offers
No deposit free bets are the holy grail of sports bonuses. This type of offer can be rare to find and usually comes with specific criteria to meet. For example, the minimum odds and bet type might be restrictive. There may also be wagering requirements which means any winnings won’t be immediately withdrawable. This type of bonus is like a no deposit or free spins casino bonus.
- Risk-Free Bets
Risk-free bets act as a safety net. They work by a bettor placing a real money bet, and if it falls short, the betting site offers a refund. Usually, the refund will take the form of bet credits to use on further wagers. Rest assured if the original bets win, a customer still gets to keep their winnings.
- Money-Back Free Bets
Similar to a risk-free bet, money-back bets offer a bonus if a bet loses, if the favorite wins, or if a certain event happens. The bonus will usually come in the form of bet credit. This bet type is hugely popular on a variety of sports, though you can usually find unique promotions for horse racing in particular.
- Bonus Code
Bonus or promo codes give access to specific offers by a sports betting site. The codes are usually only valid for a limited time with new bonus codes created regularly. They’re simple to use – when depositing, simply enter the code under the ‘Got a promotion code?’ field.
- Boosted Odds
For a limited time, betting sites offer boosted odds on specific bets. The ‘boost’ means that there’s a larger payout for the same bet. Also known as enhanced odds, this type of bonus can usually be found on high-profile events, like the NFL or NBA finals. This is a regular offer that’s valid for both new and existing customers.
- Free Bets Clubs
Most sports betting sites will offer regular bonuses to reward loyalty in the form of a free bets club. Though named differently at different sites, free bets clubs work in the same way. If a customer bets a certain amount over a one-week period, they will be rewarded with a free bet. Minimum odds often apply for the free bet.
