Our writers have worked in CRM, VIP and customer support teams at top tier online gambling operators in the UK. We have also spent time and money over the years playing slots at many of the numerous online casinos available to players in the UK.

Finding the Best Welcome Bonuses

The first feature of any slot site to grab your attention will most likely be the welcome bonus package. Making sense of it isn’t always that easy. Here is a quick guide to the most important things to look out for when weighing up each bonus

  1. How Is The Bonus Triggered?

Consider what the necessary actions are to trigger the bonus, and decide if you are comfortable meeting them. Almost every casino will gift a bonus of some sort on the first deposit made, but you should always check the minimum deposit required to trigger the bonus. Usually this will be £10 or more. Remember, depositing £5 twice will not qualify you. Also look for the maximum bonus amounts and remember that if you deposit in excess of the maximum amount, your bonus will be capped.

2. What Are The Wagering Requirements?

Always check out the wagering requirements on any bonus, or the winnings from any free spins. You will usually be required to turn over your bonus or winnings a specified number of times before a withdrawal can be made. And when hitting these wagering requirements be careful that you don’t exceed the maximum bet value – often £5 – or your wagering will not count towards the offer

3. What Game Restrictions Apply to the Bonus?

Further restrictions to look out for include the games that are available to play with bonus money. Typically slot machine sites will restrict players to wagering bonus money on popular, low volatility slots like Starburst. The chances are you won’t be spending your bonus chasing those big wins on your favourite progressive jackpot game! That said, you should always shop around because some bonuses are more flexible than others

4. Is Your Payment Option Valid for the Bonus?

For those who like to deposit using eWallet payment methods, check the terms of the sign up offers to see if your preferred option will make you eligible for the bonus. Typically, Neteller and Skrill are not valid.

5. Does the Bonus Have an Expiry Time?

Finally, if you are not planning to wager all that bonus money on day 1 then we urge you to take heed of the expiry terms of your bonus. Usually a bonus will be available to claim from registration for seven days or more – though some slot sites may restrict this to just 48 hours – and the bonus itself will be valid for up to 30 days before it is forefeited. So, don’t forget those bonus funds – they are there to be spent.

Casino Bonuses, Advertising Standards and Transparency

The online gambling industry came under close scrutiny in 2017 following some high-profile cases that were also widely reported in the media in which advertisers were seen to be using questionable practices and socially irresponsible content to push gambling offers.

At TheSlotBuzz we aim to make the terms of all the offers listed on our site very clear and transparent and to follow all guidelines on compliance to the letter.

Advertising codes are written by the Committees of Advertising Practice (CAP) and applied by the Advertising Standards Agency (ASA). They include guidelines stating that gambling advertisements should not appeal to those under 18, promote gambling as a means to resolving financial problems, or suggest any link between gambling and sexual success.

Slot Game Software

For many of us of course, the most important feature of slots sites will be the games on offer. There are many different software companies out there, from industry giants like Playtech, Microgaming and NetEnt, to newer studios like Red Tiger Gaming and Thunderkick. Each will have their own graphical styles and game types, with varying volatility, RTPs and maths models.

Not every casino brand is in partnership with every software supplier so before you make a deposit you should look to see which slots you can play at each site. Some brands sign exclusive deals with one supplier – this is common in the case of Playtech and Microgaming. Others will partner-up with multiple suppliers to provide a wide range of games. For our money, the latter are the best sites to play at, offering the widest choice in their game catalogues.

You can see which suppliers are working with each slot site in our listings. For more information read our casino gaming software page and reviews of the major slot game suppliers.

Cashier Options at Slot Sites

There are many different ways to deposit and withdraw into your online casino account. Whilst the debit car options will always be the most popular, there are plenty of other methods to consider, each with its own merits. We recommend looking at eWallet solutions like Paypal which are very popular and allow customers to manage their gambling spend across multiple sites from one wallet safely and securely.

Check our casino payment methods pages for more information about this.

A Note About Licensing for UK Slot Sites

All the slot sites listed and reviewed at The Slot Buzz are licensed by the UK Gambling Commission. Under the terms of these licenses, casino operators must offer a fair, safe and secure service to their customers, or they risk penalties, including fines, or in extreme cases, having their licenses revoked.

This means that you can feel safe that your data is well protected, your financial transactions are secure, and the gameplay at your casino is fair. It also means that should you have a complaint to raise against an online casino then you have recourse to do so. You can read more about this in our Fair Play gambling guide.

Most operators have businesses based outside the UK in other gambling jurisdictions like Malta, Alderney or Gibraltar, from which they will also have been issued with a separate license. At TheSlotBuzz we have listed information about each jurisdiction, including contact information and complaints procedures, on our licensing pages.

Slots and casino games pay out according to the metric of Return To Player (RTP) which shows how much money will be paid back in winnings from all the money wagered.

The games look best on full screen phones and it is possible to sign up, deposit and play entirely from a hand-held device. There are also now payment services that allow players to deposit through their mobile without the need to use a bank account. Payments are added to the customer’s monthly phone bill or deducted from their pay as you go credit balance.
