Top best signup bonuses in the UK


There is a truly amazing and diverse variety of gambling websites online today. Important casinos that care about their customers compete for your attention by offering you dazzlingly great deals for signing up and getting straight to the fun part and trying their vast selection of games. The UK Gambling Commission alone registers over 340 casinos active in the UK, many of which you may be no doubt quite familiar with. A significant number of these casinos will continue to give you bonuses for remaining a loyal customer on their website! Sounds good doesn’t it?


Types of signup bonuses


The terms used to describe these bonuses may vary from site to site, but ultimately, they are divided into two broad categories. These categories are the following:


  • Free, no deposit bonuses

Often smaller than their deposit based counterparts, the no deposit bonuses will give you something, often free spins, just for signing up. Alternatively, you will be given a small sum, around 5 to 10 pounds, to play around with. This amount changes from casino to casino. Many casinos offer much higher no deposit bonuses!


  • Deposit based Bonuses

Deposit based bonuses require you to deposit some money, but your bonus depends on how much.

For instance, you may come across a website that will add fifty percent more credits to your account than what you actually added. If you deposit 100 pounds, you will actually get 150 pounds!


When you pick your casino, you should always make sure to check out the terms and conditions involved. Casino bonuses may differ from country to country and some casinos do not offer any bonuses to certain countries, in order to ensure legal compliance. Therefore, you might find yourself in the unhappy situation of not being able to collect said bonus. Make sure to avoid that! We can help you! Check out our great selection of casinos that you can try your luck at in the UK!


You should also be aware of the inconveniences presented by issues such as expiry dates, wagering requirements and accepted currencies. Always make sure you’re getting the most value out of whichever casino you sign up to. If in doubt, ask the casinos customer support team!


No deposit signup bonus


First of all, let’s discuss the No Deposit bonus. This particular bonus is recommended for beginners, as they allow you to learn the ropes of online casino gaming without risking much, as you do not need to put much in right away in order to play. Only your time!


There are not many casinos that offer these, and when they do, the bonus tends to be rather small. Once you play a few rounds on the house, you can continue with the advantage of knowing your way around the game instead of starting from scratch. Care to try? Check out the no deposit bonuses we recommend on Mad Casino Bonus!


Many of these casino bonuses come under the form of free bonus spins. Whether these are free bonus spins no deposit or not, they are never a mere afterthought, as they are given for fan favourites like Book of Ra, Starburst or Shining Crown.

Deposit Bonuses


As for Deposit Bonuses, they can generally be categorized into the following groups:


Matching deposit


With matching bonuses, the casino will match your deposit with a bonus based on a casino specific percentage that differs from casino to casino.

As such, if a casino offers a bonus of 100% up to 50EUR, you will play with 100EUR while depositing only 50.


These bonuses are your friends in time of need if you aren’t comfortable with playing as much as you’d like to. You get twice the fun at only half the price. Sounds like a plan!

Many casinos will increase the percentage of matched bonuses based on how many deposits a player has made, in order to keep players on their casino instead of switching to a new one. Keep in mind that many casinos will also offer you free bonus spins together with these increases! A sharp eye and your good judgement are your trusty companions when exploring the marvelous world of casino gaming.


Percentage Deposit Bonuses


Although they may seem similar to the matching deposits we have discussed earlier in this article, these bonuses will cause the casino to offer you a fixed percentage for the amount you deposit. These are lower than matched deposit bonuses, but they are still worth looking into in case you find something that piques your interest.


Reload bonus


Reload bonuses can also be found on most casinos. The amount is often low, however, this is made up for by the fact that they are, as the name suggests, recurring bonuses. You will often be notified of these bonuses through emails from the casino, so check your inbox! Alternatively, you may be eligible for these bonuses by making a deposit at a fixed interval which will be specified by the casino. The interval varies from one casino to another.


However, please keep in mind that many of these bonuses have their own wagering terms attached, so choose accordingly.


High Roller bonus


Last, but not least, the High Roller bonus is yet another type of percentage bonus, generally reserved for the players who deposit large sums. It stands to reason therefore that the minimum deposit amount needed to gain this bonus is higher than the other kinds - but so are the rewards. If you’re feeling confident, don’t hesitate to go for one of these! Become the king of online casino gaming with the best signup bonus ratio around! Are you ready to show everyone else how the game is played? Fortune awaits.
