MadSlots Casino might have gone a bit mad hoarding such a massive game selection. You have a casino site that carries nearly 2,000 games, fast payments, and great promotions. but the madness doesn't stop there.

First, their deposit bonus comes with a 30x wagering requirement, which is easier than the average UK wagering. On top of that, the casino offers up to 100 no-deposit spins for all new players - that's a hundred free spins with no deposit required!

There are more bonuses to be claimed with the second and third deposits, and the bonus T&Cs are equally reasonable. You can get the welcome bonus deal for as little as £10.

What Is a 100% Casino Bonus

What is a 100 deposit bonus and how it works

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.

Examples How the Bonus Works

Out of the best 100 welcome bonus offers, approximately 60 per cent are 100% deposit bonuses.

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.

If you deposit £50, another £50 will be added as bonus money.

Casinos usually separate these two balances. Therefore you will have your actual deposited cash balance and a bonus balance shown 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.

Terms & Conditions for 100% 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. 

Comparison With Other Deposit Bonuses

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!

200% Deposit Bonuses

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.

300% Deposit Bonuses

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

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.

500% Deposit Bonuses

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.

Responsible Gaming and Casino Bonuses

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.


A 100% deposit bonus is a bonus offer from the casino to its customers. You will get bonus money on top of your deposit and double your bankroll.

For example, if you deposit £50, you get an additional £50 as bonus money. Bonus terms and conditions vary in casinos, so make sure you read them through before accepting the bonus.

You can get a 100% welcome bonus by registering to a casino that has this offer. You can find and compare options on our casino toplist.

After you find a suitable casino for you, register at the casino and make a deposit. Remember to check the bonus terms and enter the bonus code, if applicable. The bonus will be added to your account and you can start using it.              

100% casino bonuses work by giving you bonus money relative to your deposit. For 100% bonuses, you get the same amount of bonus money that you deposit.

These bonuses always have a maximum listed, and depositing more than that only gives you the set amount of bonus money.

Bonus money has terms and conditions, but it can be used to win real cash.

The sites that offer 100% casino bonuses can be found on our list above. Bojoko has reviewed these casinos so that it's easier for you to compare and make your pick.

Remember to always play and enjoy your bonus responsibly. In that way, you can get the best out of the 100% deposit bonus and it will add value to your casino experience.
