Duelz is a unique online casino with a 100% welcome bonus. It focuses more on social gameplay and challenges.
When Duelz was released in 2018, the casino stood out with two features that no one else had done. The first was that they were a mobile-only online casino, and the second was that players were supposed to challenge other people in duels to get extra payouts. While the casino does support desktop computers nowadays, the duelling is still a thing.
Duelz has a 100% match bonus ready for all new players. You get a 100%/£100 + 100 bonus spins when you make your first deposit to the casino.

We rate 100% casino bonuses by comparing their value, fairness, and terms across the industry. Our experts break down each bonus to help you find offers that are worth claiming.
We use these criteria to compare each 100% bonus against others on the market and highlight the ones that are the best.
You can read more about our online casino review guidelines and learn how we rate casinos and their bonuses. Our casino experts have a long history with online casinos and their bonuses, and use this experience in their reviews.
At Bojoko, we not only list 100% bonuses, we break down their pros and cons for you to see their real value. Our bonus team has years of hands-on experience with online casinos and understand how bonus terms affect real players. That means we go beyond the surface to analyse the full picture: wagering requirements, deposit limits, game restrictions, and withdrawal caps.
We independently test every bonus we rate, comparing it against others in the UK market. If an offer looks generous but hides strict conditions, we'll point it out. If there's fair terms and actual value, we'll highlight that too.
A 100% casino bonus is a casino's promotional tool that gives you bonus money relative to your deposit. It is used to entice new players into joining a casino by letting them play with more money.
The bonus percentage and the maximum bonus amount tell you how much you can get. With a 100% bonus, you get the same amount of bonus as you deposited up to the maximum listed on the offer.
100% bonuses are offered for various things in casinos. You can use it on slot games, crash games, betting or sometimes it can be given to you as a live casino bonus for table games. Always check the terms so you know which games can be played.
Let's look at the following welcome offer: 100% match bonus up to £100. The percentage stands for the percentage amount you will gain as a bonus, and the £100 stands for the maximum possible bonus amount.
In this case, you will get 100% more on top of your own deposit. If you deposit the maximum amount, you will have £200 in your account. Check the minimum deposit limit and make sure you deposit at least that amount.
Casinos usually separate these two balances. Therefore, you will see your actual deposited cash and bonus balances in your account. Every casino also has its own terms and conditions for 100% match bonuses. That's why it's always wise to read casino-specific terms before accepting bonuses.
Bojoko has listed all the sites where you can get the best online casino bonus in the UK, and you can explore other bonus types too.

There are tons of great new casino releases in the UK, but not all of them have match bonuses. We have listed the best new online casinos on one handy page, where you can browse all the new casinos. But first, check out some recently opened UK casinos with 100% match bonuses.

It is very important to familiarise yourself with the bonus terms and conditions before accepting a bonus in a casino. 100% deposit bonuses come with different requirements, and each casino can set its own bonus terms. However, there are some common rules that apply to these bonuses and are often used in UK casinos.
Below you can see a list of some essential details that you should pay attention to when claiming a 100% deposit bonus:
Check out our Wagering requirements guide, where you can learn in detail about how wagering works and try our handy wagering calculator.
While a 100% deposit match bonus is a common and appealing offer, it's just the beginning of what's available. Deposit bonuses extend far beyond that, with more substantial percentages like 200%, 300%, 400%, and even 500% deals available.
However, it's important to note that bigger bonuses don't always equate to better value. Each type of bonus has its own unique advantages and disadvantages. Weigh your options carefully to find the one that best suits you!
For players who want a bit more than an equal match in bonus funds, a 200% bonus triples the amount you deposit. You get a considerable boost to your balance, and what's more, these offers are more common than you'd think.
When browsing 200% deposit bonus casinos, the thing to remember is that this is where conversion caps and higher withdrawal requirements come into play. Read our reviews carefully to get a proper understanding of the offer.
A 300% deposit bonus is an excellent choice to maximise your playtime and chances. These offers quadruple your deposit, opening the door to try out an even wider range of games and benefiting from a large starting balance without a large deposit.
The 300% mark is where most casinos have a fixed conversion cap, which is something to keep in mind when comparing your options. You can discover the top 300% deposit bonus sites to find a casino that suits your taste.
400% deposit bonuses offer an even more substantial increase to your balance. Let's think of it this way: you can get £50 to play with by depositing just £10.
While these bonuses are truly generous, they most often have high wagering requirements or a flipped playthrough. Your bonus funds can be locked until you have completed the wagering.
400% bonuses are rare, but you can find them on our 400% deposit bonus page.
A 500% deposit bonus is one of the most open-handed offers available, giving you a sixfold increase in your deposit. There have been a small number of casinos with a bounty of this magnitude on the market, but these deals are usually available for a short period.
While these bonuses are like gold dust, you can discover them on our 500% deposit bonus page, which is updated with these offers whenever they appear.
Typically, these bonuses are available when you make your initial deposit. However, top-tier casinos take it a step further by regularly rewarding their existing players with deposit bonuses to boost their balance. These offers are called reload bonuses. You can learn about them on our reload bonus page.
Bonuses are one way to attract players to the casino. They are an effective marketing tool for casinos in the ever-growing gambling industry. The competition is tough and new bonuses are invented all the time to keep the game on.
It is important to stay in control of your own gambling. Take advantage of the responsible gaming tools that the casinos offer, set your limits and stick to your budget. Don't ever use gambling as a way of making money, and don't bet more than you can afford to lose.
