Best for: The biggest bonuses on the UK market 🚀

Fortune Mobile Casino stunned me with one of the largest bonuses available on the UK market worth £500 over 3 deposits. This is a full £200 more bonus cash than the next biggest bonuses available at Dream Vegas and Grand Ivy. To sweeten the deal there are a further 150 free spins available on three leading NetEnt slots to claim. When I explored their promotional page I saw that there is plenty for existing players too. Deals like Weekly Wheels and Cash Spin Prizes mean the rewards keep on coming.

👨‍💻 User review: There are no user reviews for this casino just yet but we will update this section as soon as there is!

💡 Expert insight: "Fortune Mobile Casino offers a very impressive bonus with below-average wagering. The devil is in the details though. You will need to make 3 deposits to claim that full amount. Nevertheless, it is a market-leading bonus for the UK."

Different types of casino bonuses

The range of casino offers available is diverse and each one can benefit you in different ways.

Depending on the games you like to play, how you play, and how much you play, you should choose a bonus that reflects this. Let's take a look at the most common bonus types.

• 👶 First deposit bonuses

  A first deposit bonus will be a percentage of your first deposit to a casino matched in bonus money. One of the most common examples of this would be the 100% up to £100 deposit bonus match. In this case, the casino bonus will be the same amount as your deposit in bonus cash.

  ✅ My top picks: Pub Casino (100% match) & Grand Ivy Casino (150% match)

  
• 🎰 Free spins bonuses

  Free spins are a welcome bonus for slots. Games are pre-selected and can include titles like Big Bass Bonanza, Starburst or Book of Dead. You can even find free spins with no wagering that let you keep what you win.

  ✅ My top picks: Magic Red Casino (100 wager free spins) & Betway (125 wager free Spins)

  
• 💰 No deposit bonuses

  No deposit bonuses remove the need for you to make a deposit. All you would need to do in this case would be to register your details, opt-in or add a bonus code, and you will receive a casino bonus without making a deposit. These are generally a small cash amount or a low number of free spins.

  ✅ My top picks: Alladin Slots (5 no deposit free spins on Diamond Strike) & Cash Arcade (5 no deposit free spins on Chilli Heat)

  

Available bonuses for returning players

It's not just new players that get online casino bonuses. A wide range of casino offers are available for existing and loyal players with new offers daily, weekly, and monthly including exclusive mobile offers and more.

💡 Expert insight: Most casinos will offer an optional email list with exclusive offers and bonuses. Make sure you opt-in on sign up to get juicy offers periodically with public holidays like Halloween and Christmas bringing particularly beefy bonuses.

Check out some top bonuses including:

• 🎰 Deposit bonus

  A deposit bonus is any existing player bonus that requires an additional deposit amount to access. These can come in the form of bonus funds, free spins or free bets on live casino games depending on the offer.

  For example: Deposit £10 or more to get 25 Free Spins on Book of Dead

  
• ☃️ Seasonal casino bonuses

  Casinos also like to celebrate the most wonderful times of the year with special one-off promotions. These will usually be centred around seasonal themed games to maximise the spirit of the season.

  For example: Most casinos run special promotions around holidays like Christmas or the Summer holidays

  
• 💰 Cashback

  Cashback bonuses award a percentage of your total bets back periodically as bonus cash. These can be on our total betting amount or can be applicable on all real money losses.

  For example: All British Casino offers a 10% cashback offer on all weekly losses on slots

  
• 📱 Mobile casino offers

  Some casinos will offer exclusive bonuses for verifying your mobile number or playing on a casino app.

  For example: Verify your mobile number for £10 in bonus bets

  
• ⚔️ Tournaments & bonus games

  Casinos will offer exclusive bonus games and tournaments giving you even more chances to win prizes. These can run periodically including some casinos offering a daily free game that can be played each day you log in.

  For example: Casinos will offer exclusive 'tournament-style' games including Reel Rivals player-vs-player games.

  
• 🗓️ Loyalty programs

  Loyalty programs are a type of casino offer where players benefit from recurring, frequent casino bonuses by returning and playing at a casino regularly. They often work in a tiered system with better rewards for the more consecutive days you log in.

  For example: Log in each day of the week to unlock 10 Free Spins on Big Bass Bonanza

  Bonus type

  First, we examine the types of casino bonuses available. Whether they are match deposits, free spins, or no deposit bonus offers, we explore the details. We also check what makes each casino's bonus unique to get a clear scope of what's available in the market comparatively.

  At All British Casino, not only can you get 100% on up to a £100 deposit, but you can also get 10% cashback on all slot game losses every week. This highlights the casino as bringing a unique flavour to the standard match offer and sets it apart from the crowd.

  💡 Editor’s insight: No deposit bonuses are top of the charts when it comes to recommending a casino. Having the ability to bag some extra spins or funds without an initial investment should be an early consideration when picking a casino.

• 

  Bonus value

  We then look to see how much the casino bonus offers and if the value is worth it. The standard is a 100% match bonus on up to £100 deposit, as shown by casinos like Pub Casino, with anything above this putting a casino offer above the crowd.

  Grand Ivy Casino offers a 150% bonus up to £300 - which is significantly higher than many casino deposit bonuses available.

  💡 Editor’s insight: Be careful on how you value each casino's contribution. Some will promise big bonuses with even bigger wagering requirements attached so do the maths before dedicating to an offer.

• 

  Game selection

  For casinos that offer free spins, the selection of qualifying games plays a massive part in how we recommend a casino offer. A top casino bonus will offer free spins on popular titles from top software providers like Blueprint or Pragmatic Play as they represent the highest quality slot games on the market.

  Betway Casino stand out as a top choice as they offer 125 free spins on Big Bass Bonanza as part of their welcome offer; a top choice for UK slots players and spins equating £12.50 in value.

  💡 Editor’s insight: Prioritise casinos that offer titles from the top providers around. Microgaming, Pragmatic Play and Netent are top of the list as they provide some of the fairest and highest quality titles around with RTPs of over 95%+.

• 

  Wagering requirements

  One of the biggest terms and conditions that could affect the potential of a casino bonus is the wagering requirements. The standard wagering requirements range from 35x to 40x, with bonuses with low or no wagering requirements considered especially impressive.

  Magic Red offer 100 free spins with no wagering on Fire Joker meaning any winnings are yours to keep as real money.

  💡 Editor’s insight: Always check the wagering requirements of a welcome offer before putting down your cash. 35x is the standard in the UK but casinos will frequently be lower than that to try and entice you further to sign up over competitors.

• 

  Overall experience

  Finally, we look at the complete experience the casino offers UK players. An online casino is only as good as the sum of its parts including site functionality, mobile accessibility and customer service.

  All British Casino stands out in this category as it offers native app support for both iOS and Android as well as exceptional 24/7 customer support.

  💡 Experts insight: If your favourites sites don't offer a native app, favouriting the page will give you an easy shortcut back when you need to come back later.

Top UK slot games

While every online casino brings a different welcome offer to the table, there are some usual suspects that will pop up frequently when a casino offers a bonus spins or free spins promotion.

💡Expert insight: The games that make up a casino's welcome offer are generally the top performer for a provider or player favourites. These are titles that have amassed a dedicated following because of their high production value, exciting bonus features or high payout potential.

Check out some of the top titles below and play for free right now before you dive into the world of real money slots. Think of it as our personal 'try before you buy' before dedicating to a specific free spins bonus.

How do wagering requirements work?

Wagering requirements refer to the amount of money you need to bet before you can convert bonus funds into real money.

When wagering requirements are applied to a casino bonus, you will need to fulfil its requirements over time to turn any of your bonus winnings into real money. These can be achieved on online slots, table or live dealer games depending on the bonus offers T&Cs.

💡 Experts insight: The standard wagering requirements for a UK casino is 35x so keep an eye out for casinos that offer lower requirements or no wagering bonuses.

Let’s take a look at a real-world example from some of the top UK online casino bonuses:

My top tips for making the most of casino bonuses

It's important to know what you're signing up for when you're looking for a gambling casino online bonus. Here are our top tips to be mindful of as you shop around for your next casino bonus.

💡 Experts insight: Doing your homework is key to getting the most of your casino bonuses. Don't feel like you need to dedicate to the first decent bonus you find as there could be juicier choices on offer.

• Check wagering requirements

  Find out how many real money bets you have to make to be able to withdraw your bonus money from your casino. Generally, these will be around 35x but can be higher depending on the casino bonus on offer.

  💡 Experts insight: Be careful of casinos that offer massive bonuses as these will be harder to meet the wagering requirements and can generally come with higher wagerings (up to 50x).

  
• Check the deposit match contribution

  All casinos that offer a deposit match bonus will be capped on a certain percentage and deposit value. The standard is 100% on up to £100 so make sure you maximise your total available deposit match and understand what your limits are for claiming bonuses.

  💡 Experts insight: Keep your eye out for casinos that offer above the standard 100% for £100 match like Mr Mega (100% up to £150) or Grand Ivy Casino (150% up to £300) so you're getting the best for your deposit.

  
• Be mindful of time limits

  Most casino bonuses that have wagering requirements will also have a pre-set time limit to fulfil your wagering. Make sure you understand fully how much time you have before dedicating to ensure meeting the requirements are feasible for your play style and budget.

  💡 Experts insight: If you're worried about not hitting your time limit, set a reminder on your phone calendar so you know exactly how long you have left.

  
• Take advantage of no wagering bonuses

  No wagering bonuses should be a key consideration when selecting a casino as there are no harsh wagering requirements to be mindful of. Everything you get, including real money winnings, is yours to keep.

  💡 Experts insight: Most no wagering bonuses will be in the form of free spins so they are perfect for slot fans

  
• Always check the T&Cs

  People generally don't pay attention to T&Cs but, in this case, it is vital to know exactly what you're getting into and avoiding any nasty surprises. Have a glance over to check for details like time limits, wagering requirements or max win restrictions before you dedicate to a casino bonus.

  💡 Experts insight: No need to crack out the legal team for this one as casino T&Cs are generally straightforward and give all of the most important info in a convenient numbered list.
