The best 500% casino bonus for UK players

Best UK casinos with a 500% first deposit bonus

Are you ready to get down with a 500% bonus? If you already know what these bonuses are and just want to find casinos to play them in, then wait no longer.

These bonuses are very rare, so there is only a limited number of UK casinos that have them. Here are the ones that we recommend.


BoyleSports has a 500% welcome bonus for UK players

BoyleSports is a name you might be very familiar with outside of online gambling. They are the largest independently owned bookmaker on the island of Ireland. The company's history goes back to 1982 when John Boyle opened his first betting parlour.

In 2021, they took the leap online and thus, BoyleSports online casino was born. It has experienced people behind it and shares the same high quality standards as the brick-and-mortar betting shops.

For an online gambler, BoyleSports is an all-in-one casino. This means they have slots, live casino, online bingo, lotto and online poker all under one roof. So, whatever your fancy is, they have it.

What is a 500% casino bonus?

A 500% casino bonus is an extraordinarily large welcome gift that gives you 500% of your deposit in bonus money. The idea is that the casino will top off your account with bonus money when you make a deposit to make starting easier.

The bonus percentage, in this case 500%, tells you how much money the casino will give you. It is that many percents of the deposit you make, so for a casino with 500% bonus, they will add five times the amount you deposit in bonus money on top of that.

Deposit £10 and the casino will give you a £50 bonus

As the bonus percentage grows, commonly the maximum bonus will shrink. The casino wouldn't stay in business for long if it gave out hundreds and hundreds of pounds in casino sign up bonuses to every player.

Like every other bonus offer, a 500% casino bonus does have its own terms and conditions. It is important to read them first, byt most of them just boil down to the fact that the casino wants you to use the money to play.

Pros and cons of 500% welcome bonus

Just like with all bonus offers, there are pros and cons when it comes to 500% casino bonuses. The bonus is big compared to your deposit, but a deal like that comes with its own rules and drawbacks.

Here are some of the most notable pros and cons of 500% bonuses

✅ Large bonus with a small deposit
✅ Good way to test the casino
✅ Best value for money

❌ Rare to come by
❌ Terms are stricter
❌ Maximum bonus amounts are smaller

Find 500% casino bonuses

New 500% deposit bonus casinos in UK

Finding new casinos with high bonuses is always a treat. Though, it needs to be said again that these bonuses are so rare, that new 500% bonus casinos are pretty much unicorns. If you see one, you should take a closer look.

If you are just looking for a fresh site, you can find new online casino sites on our dedicated page.

Terms and conditions of 500% first deposit bonuses

All bonuses have their own terms and conditions, and 500% first deposit bonuses are no exception. In short, these bonuses have fairly tight terms, but not in places that you might think.

The next questions is obviously what are wagering requirements, and you can read all about them in our wagering guide. Simply put, wagering requirements just mean that you must play with your bonus money for a certain amount before you can take it home. They are shown as a multiplier of your bonus amount, and can vary wildly between casinos. A large bonus percentage doesn't automatically translate to a large wagering requirement.

Big bonus percentages often mean small maximum bonuses. On the other hand, this also means that you can get the full bonus with a very small deposit. Often a tenner is enough.

Deposit bonuses seldom have withdrawal limits, but it is always good to check. These caps mean that after the wagering is completed, you can only cash out a certain amount from bonus funds.

Comparison with other deposit bonuses

The world of UK casino websites is full of bonuses of varying sizes. Sometimes finding the right casino with a 500% match bonus is difficult, so it might be a good idea to check other bonuses as well.

You can take a look at our other deposit bonus pages and see if there are casinos that suit you better. If not a full 500% match bonus, then maybe something a little smaller.

Deposit bonuses and responsible gambling

Bonuses are a nice thing that casinos offer to new customers, but in the end they are a marketing tool. Their goal is to get new players to join the casino and deposit money. The more they offer, the likelier it is that players want to deposit.

In the end, casinos are in a business to make money, so the terms of the bonuses are tweaked so that the casino will win most of the times. It is important that you know what you are signing up for and what you need to do to actually get something from the bonus offer.

Taking a bonus is all fine and good, but remember to read the terms. Never deposit more than you can afford to lose.

Gambling is a form of entertainment and not a way to make money.


A 500% deposit bonus is a gift from the casino to new players and it gives you 500% of your deposit in bonus money. The casino will add bonus money to your casino account up to a set limit depending on how much you deposit.

For example, a casino with a 500% deposit bonus will give you £50 extra when you deposit £10.

You can get a 500% welcome bonus by finding a casino that offers them and then just by making a deposit. In most cases, the bonuses are paid automatically, though you should check if you need to tick a box or add a bonus code to get it.

You can find casino sites with a 500% welcome bonus right here on Bojoko. We test and review the sites so you know what you are in for.
