What Is a 100% Deposit Bonus and How Does It Work?
A 100% deposit bonus is an offer that rewards players with the same value (100 percent) of their deposit in bonus funds. Players can choose to spend this on bonus slots, casino games, or whatever else the T&Cs allow.
Often part of a welcome bonus, a 100% matched offer is generally used to attract new players, but it’s possible to find these for existing players, too. A 100% offer effectively doubles a player’s spending power. Here are the main benefits:
- Deposits last longer
- Choice of how to spend it
- Try out games for free
- Reduced financial risk

Important T&Cs of 100% Deposit Bonus UK Promos
There are certain terms and conditions that players in the UK need to be aware of when claiming a deal. In this section, we’ll cover what these main T&Cs are and what you, as a player, should be looking for.
- Wagering requirements: Wagering requirements state that the value of a bonus needs to be re-wagered a certain number of times before it can be withdrawn. In the case of a 100% deposit bonus, this would likely be between 30x and 60x. A lower number is better, as it means that you’ll be able to withdraw your cash sooner.
- Maximum win: Maximum wins (also known as win limits or win caps) dictate the maximum amount that you can gain from a single bonus. Not all promos will have these, and they can vary greatly. Some may limit your winnings to £20, whereas others will be thousands of pounds. Always look for this in the terms and conditions when claiming any promo.
- Time limits: Time limits force players to use bonuses within a certain timeframe. This will usually apply only to the bonus and not to the deposit funds. If, when time runs out, the bonus hasn’t been used, it will expire, and you won’t have access to it. Time limits can be anywhere from a number of hours to months, so don’t get caught out.
- Payment method: Certain promos require the player to deposit using certain payment methods. Generally, you’ll be able to use debit cards, but there may be restrictions on certain e-wallets and other payment types. When depositing to your account with a promo in mind, always check that you’re using the right payment method.
- Game restrictions: It’s often the case that certain bonuses can only be used with certain games. These eligibility restrictions may apply to specific titles or to entire parts of the casino site. For example, some may state that a bonus can only be used on a number of pre-selected slots, whereas others might be usable anywhere in the live casino section.
- Bonus code validity: Bonus codes aren’t always necessary, but sometimes they can help you get the most valuable promotions. Often, codes will be displayed in the terms and conditions, but sometimes, you’ll find them in emails and promotional materials. Consider making a note of any bonus codes you come across.
100% Deposit Match Bonus: The Pros & Cons
All different promotion types come with their own pros and cons – their strengths and weaknesses – and you need to be a smart player to weigh these up before jumping in. Like all promos, these have advantages and disadvantages, which we’ll explore now.
How Can I Claim a 100% Deposit Bonus?
The process of claiming a promotion at a first deposit bonus casino is generally straightforward, and it doesn’t vary much from one casino to the next. Here’s a general overview of the steps to claiming yours:
- Select your chosen bonus from our list above.
- Head over to the site and click ‘register’ or ‘join’.
- Complete the registration by entering your details and following instructions.
- Once registered, attach a payment method.
- Verify your ID by submitting the correct documents.
- Opt into your promo if necessary, and make the deposit.
- Wait for your bonus – some are credited instantly – and enjoy!
How We Test 100% Deposit Bonus Casinos
Our research has shown that there are certain criteria that are always worth looking at when assessing a casino site. When our experts review sites, and before recommending a casino or a bonus, there are certain things we always check out.
- Promotional value: One of the first things we check out is the variety of welcome bonuses, recurring bonuses, VIP programmed and loyalty rewards that the site offers.
- Game selection: Players like diversity, and so do we! It’s important that a casino offers a range of game types from various developers, or things could get stale and repetitive.
- Site navigability: A good casino site is easy to find your way around. This means responsive search functions, sensible menus, and a nice clean design.
- Fairness and transparency: We always check out the general terms and conditions as well as the bonus ones. This way, we can get a good idea of whether the site is in compliance with UKGC regulations and requirements.
- Licensing: All casinos recommended on Slotozilla are properly licensed by the relevant authorities. In the UK, this means that the Commission has approved and audited the site.
- Customer support: Everyone needs help every now and then, and it’s good to know that you can get in touch with a real person when you need to. We rate good customer support highly, as it shows that sites care about players.
100% Deposit Bonuses and Payment Methods
As we mentioned, certain promos require players to deposit using certain payment methods, whereas others give players a choice. Let’s take a look at the main payment methods players can use when claiming these and other types of bonuses.
| Payment Method | Acceptance | Withdrawal Speed | Fees |
|---|---|---|---|
| Debit Cards (Visa, Mastercard) | All casinos | 2-5 days | None |
| E-wallets (PayPal, Skrill, Neteller) | Most casinos | 1 day | None |
| Cryptocurrency | Few casinos | Sometimes instant, but it depends on the fees | Some small fees |
Exclusive Slotozilla 100% Deposit Bonuses
Our team has tracked down some fantastic exclusive bonuses for Slotozilla players. According to the experience of our experts, here are three of the very best of these that players can currently claim:
- Lucky Thrills Casino 100% up to £50 + 50 free spins on Fire Joker Freeze: This is a solid opportunity to claim a great deposit bonus with some added free spins. A £50 deposit bonus can go a long way, especially at a casino with such a wide range of games as this one.
- GreenPlay Casino 100% up to £100 + 50 spins on Gold Blitz: GreenPlay is a popular international casino with a great, clean design and some excellent returning promos. This means that, even after claiming this bonus, you’ll have plenty left to do. A £100 bonus is massive, and you don’t come across this sort of thing every day, especially with added spins!
- Jaak Casino 100% bonus + 125 spins: For fans of slot games, the Jaak Casino offer might be the best option. This is because, in addition to a generous 100% offer, it also offers 125 free spins! This is a site with a nice, simple layout and a decent selection of games, so if you’re a slot player and you’re looking for a new favourite casino, look no further.
Comparing 100% Deposit Casino Bonuses
These promos aren’t the only options available to players. Here are the different kinds of deposit matching bonuses.
100% Deposit Bonus
A 100% deposit boost bonus will effectively double the amount you have to play with. This is a great option, mainly because 100% is an affordable amount for casinos to offer, so the terms and conditions are typically not too harsh. At the same time, it’s enough to be really worthwhile for players to claim.
200% Deposit Bonus
This will essentially triple your deposit’s value. This is a substantial boost to your bankroll, and these bonuses – whilst being highly valuable – are not actually as rare as you might think. Bear in mind that as the value of the bonus goes up, so too does the strictness of the terms and conditions. This means that wagering requirements may be higher on these, and there’s more likely to be a win limit.
300% Deposit Bonus
A little more difficult to come by is the 300% bonus deposit offer. This obviously quadruples the amount you have to play with, making it potentially very valuable. Because of the value of bonuses like this, it’s generally the case that the bonus will come with strict wagering requirements. These may require you to wager the bonus value 50x or more.
400% Deposit Bonus
400% deposit bonuses are quite rare, and it’s not difficult to see why. If you deposited just £20, you’d have a bonus of £80 to play with in addition to the original £20. Consider checking out our constantly updated list of 400% bonuses if this sounds like it’s the right option for you. Also, weigh up the overall value of a 400% bonus – if the terms and conditions are strict, it may not necessarily be the promo with the highest overall value.
500% Deposit Bonus
Representing a massive bonus worth 5x your deposit (so if you deposit £50 you’d be playing with £300, including your deposit), the 500% deposit deal is a rare beast! If you come across one of these, check the terms and conditions for fairness, win limits and wagering requirements, and then grab it before it goes away! Whenever they’re available, our experts will check them for you and add them to our 500% deposit bonus page.
Summary
Our experts have found that these are some of the best promos out there. A 100% deposit boost is a great way to get started on a new site for players, plus it’s a great way for casinos to draw new players in. According to our experience, everyone can benefit from promotions such as these!
Whilst there are occasionally wagering requirements and win limits, players looking for a welcome casino bonus could definitely do worse than one of these promos. These should also appeal especially to players who are looking to explore different types of games without spending upfront.
A 100% bonus is usually very easy to claim, and the process of turning it into real cash is quite straightforward. Our conclusions indicate that satisfaction amongst all sorts of players is extremely high when it comes to these promotions, and this is why we’re recommending them to you.
