Here you will find top deals with free spins on some of the most popular slot games in the world.

Choosing a first deposit bonus casino requires careful consideration – especially when you consider you’ll be making a deposit, and further possible deposits at your chosen site.

What are first deposit bonus casino sites? These are online casinos that reward players on their first deposit, multiple deposits or sometimes no deposit whatsoever. In the UK, welcome bonuses are often triggered by your first deposit. Players will often receive bonus money or free spins, usually a mixture of both in exchange for their minimum deposit. You should always read the terms and conditions and understand any wagering requirements on the bonus.

The option that best suits you will depend on how much you are willing to deposit, the minimum deposit and the maximum welcome bonus on offer. If you’re unsure about which online casino to sign up with, we can help guide you to the latest technology, games content, bonuses and promotions currently available to UK players.

So if there’s a particular type of first deposit bonus that you’d like to consider taking, then you can compare it right here, without having to sift through hundreds of white labels and copy cat casino deals. We’ve shortlisted the best of all types for you.

Some checks to do before you sign up for your first deposit bonus

  • UK Licence – The UK Gambling Commission was set up under the Gambling Act 2005 to regulate commercial gambling in Great Britain in partnership with licensing authorities. As a regulator of online gambling operators, the UKGC provides licences to online casinos, setting out rules and requirements that help protect players and make gambling safer for consumers. They can also take action where the Gambling Commission find operators and individuals failing to follow the rules and regulations laid down. You should always check for a UK licence before signing up for any type of first deposit bonus.
  • Wagering Requirements – A casino bonus wagering requirement is a multiplier that represents the number of times you have to play though a bonus before you are able to withdraw any winnings. If you don’t meet these casino bonus wagering requirements, your bonus money will never be converted into real money for withdrawal. Not everyone is bothered by wagering requirements, but you must be aware of how they work. For instance, while a 400 deposit bonus might seem fantastic, it may have 60x wagering requirements – meaning that first withdrawal is more than a few sessions away. It’s the same as free spins, sometimes having greater wagering requirements than the first deposit match part of the bonus.
how to choose your first deposit bonus casino site
  • Free Play No Deposit Bonus Money – It’s almost impossible to find an online casino bonus in the UK that is free. If you don’t need to deposit, it’s called a no deposit bonus. Sometimes you might get something like 10 free spins, other times it’s called free play. But most of the time, it’s called bonus money. Just be aware that when you sign up to play with no deposit bonus money, free play wins are also subject to any wagering requirements – meaning more wagers. Secondly, wins from using free play bonus money will be limited.
  • Deposit methods not eligible for the welcome bonus – You should always read the fine print when it comes to casino bonuses, especially as not all deposit methods will qualify for the welcome offer. Studies have shown that less than 10% of people read the full terms and conditions, we’re all guilty – but you could be wasting your first deposit bonus by avoiding T&Cs. Skrill and Neteller, for example, are two deposit methods that don’t qualify at first deposit bonus casino sites in the UK.
  • Minimum Deposit – If you sign up for a 100% deposit bonus up to £50, deposit £10 but the minimum deposit is £20 – you won’t get any of the deposit match bonus. But don’t worry, each casino bonus at Slotsquad will tell you the minimum deposit you’ll need to receive the welcome offer in your account.
  • How easy is it to claim your casino bonus? – Claiming your first deposit casino bonus should be relatively straightforward, but some sites are different than others. Even so, there are ways to ensure you don’t miss your sign up deal. By reading the instructions, we can see how easy it is to claim your casino bonus. Sometimes it’s automatic, other times you’ll need to opt-in with the cashier, and then there are email links. Also, casino bonuses in the UK are only credited and valid if claimed within 24 – 48 hours. Don’t miss your window!
  • Percentage of deposit match bonus – Depending on how casinos advertise their welcome bonus, you might be familiar with terms like 200 first deposit bonus, 400 deposit match or 500 first deposit welcome offer. You’ll find two values in every sign up bonus. The first is the percentage of your deposit match; the second is the maximum you can get from your first deposit/deposits. 100% is the most common, while 500% is one of the most lucrative values on the market. But it’s worth doing some basic mathematics. Let’s explain; you’ve got two offers. 50% up to £200 or 100% up to £100? It’s the same deal.
  • Maximum Bonus – The maximum amount of a casino bonus means that no matter how much you deposit, you’ll only receive the maximum bonus of the offer. Sounds simple, and it is, but sometimes – bigger isn’t always better. If casino A offers a 100% bonus up to £50 and casino B shows the same deal, but to £100, it seems like a no brainer. But here’s the thing, you’ll play through the wagering requirements faster if you choose casino A over casino B. Second, in this scenario – the wagering requirements could change everything.

First deposit bonus casino and free spins

UK online casinos often use different terms to describe their sign up bonus and welcome bonuses. Which can be confusing. Let us help explain some of the types of offers below:

  • Free welcome bonus no deposit required – This type of sign up offer is best if you don’t want to play for real money, but still want some kind of online casino experience. Free welcome bonus no deposit required casinos can offer between 5 and 30 free spins when you sign up – just be mindful of the T&Cs, wagering requirements and caps on any winnings from your bonus. Free spins on sign up is a popular choice if you’re looking for freebies.
  • Free spins welcome bonus – Some first deposit bonuses focus on free spins instead of matching your deposit with bonus money. You sign up to a casino, deposit the minimum (usually £10) and receive free spins on selected online slots. Sometimes it’s on one popular slot game like Starburst; other deals can include several casino games. The best value is the free spins welcome bonus with a high number of spins, reasonable set values and a fair minimum deposit.
  • Match your deposit bonus – You’ll find few casino sites in 2024 that don’t match your first deposit. At the very least you’ll find a 50% match bonus with most casinos offering a 100% double your money deal. You can almost always improve your casino account balance with bonus money on your first deposit. Depending on which casino you sign up with, match your deposit bonuses can offer up to 200% of your initial deposit as a bonus.
  • Casino bonus code and promo codes – Some operators will occasionally give out promotional codes as part of specific welcome offers. A bonus code consists of letters and/or numbers that players use when they sign up. Promo codes also provide customers with extras, including free spins or a more significant deposit match. The best times for casino bonus codes is at Halloween, Christmas and other seasonal holidays.
  • First deposit bonus casino and free spins – These are usually the top choice if you want the best of both worlds. In 2024, it’s not uncommon to find a first deposit bonus casino with free spins in the same offer. In fact, it’s quite the opposite. Most sites use hybrid deals as an incentive for your registration. And some are pretty good. This type of bonus mixes a deposit match with additional free spins – sometimes as many as 200 free spins.

New online casino bonuses

With so many casino bonuses to choose from, it can be a bit of a minefield. Do you want free spins no deposit? A 100 first deposit bonus or a hybrid deposit match with free spins? Do you want low wagering, no wagering or don’t care about wagering? Fear not, we’ve collated new casino bonuses from the top sites in the UK. Just pick a casino you’re interested in and you’ll find the new bonus listed for that particular site.
