The 100% casino bonus is one of the most common and attractive casino offers available. But how does it work exactly? A 100% casino deposit bonus is what it sounds like – it's a bonus that doubles your deposit, giving you more funds to play your casino favourites!

Why Trust Mr. Gamble?

For the safety of players and to keep operators accountable, the team at Mr. Gamble implements a world-class evaluation process for all online casinos. The team incorporates a strict due diligence process for listing casinos on Mr. Gamble by verifying the operating regions of casinos and the validity of local licenses, among other aspects such as customer service, game selection, banking methods, and bonuses.

Our editorial policy includes fact-checking all casino information while including real-world data to provide the most relevant and helpful guide for readers around the world. At Mr. Gamble, the players' safety and satisfaction are our top priority — you can rely on us to get the best possible offers from licensed online casinos.

🤔 What Is a 100 Deposit Bonus?

A 100 deposit bonus, also known as a deposit match or a match bonus, is a promotional casino offer that doubles your deposit. So you can play your favourite casino games with money equal to the amount you deposit.

It’s probably the easiest bonus to wrap your head around because it requires very little mental gymnastics to figure out.

For example: if you make a deposit of £50 and claim the 100% deposit bonus, you would get £50 in bonus funds, meaning you’d have £100 in your casino balance to play with.

Reasons to Claim a 100 Deposit Bonus UK

There are many advantages to claiming a 100 percent casino bonus, including:  

  • Try new games for free – you can use your extra bonus money to try new games without spending your own cash.
  • More chances to win – your deposit gets doubled and your gameplay extended, which increases your chances for a win.
  • Play different games – a 100 casino deposit bonus, as opposed to free spins, can be used on a variety of games, such as slots, live casino and table games. Although, live dealer games often come with their own exclusive deposit bonus offer.

100% Deposit Bonus Terms and Conditions

Before you claim your bonus at a 100 bonus online casino, you should take your time to thoroughly read the terms and conditions of the offer. They can include the following: 

TermDescription
Skrill & Neteller deposits excluded These e-wallets are sometimes excluded from casino bonuses due to bonus abuse.
One 100 welcome offer per account100 bonus on first deposit offers are reserved for new players. So if you have a verified account with the casino already, you cannot claim it. But you can benefit from 100 reload bonuses.
The winnings from the 100 bonus need to be wageredYour winnings from the bonus need to be wagered before they can be converted into real cash and withdrawn.
UK players onlyThe bonus can only be claimed if you reside in the UK.

How to Claim a 100 Casino Bonus? Simple Steps

If you’ve come across a 100 bonus you want to grab, just follow these easy steps to claim it:

  1. Choose a 100 match bonus casino offer that works for you.
  2. Click the link in the offer and we’ll redirect you to the online casino.
  3. Check the T&Cs of the bonus.
  4. Create your free online casino account at a licensed casino.
  5. Make the first deposit using your preferred payment method.
  6. Enter the bonus code if needed.
  7. Get 100% extra in bonus funds – it will be added directly to your casino account.

After you have claimed the 100 deposit bonus, you will receive your bonus money in a separate balance from your real money balance. However, this doesn't mean that you cannot win real money with your bonus money. It just means that you will have to wager your bonus money a certain number of times before you can cash it out.

How to Choose a 100 Casino Bonus?

Claiming a 100% deposit bonus can be beneficial for many reasons, but do you choose the best one? Follow these easy steps to choose the best 100% deposit bonus offer.

Easy to come by. A 100% bonus is the most common match bonus out there, so there are a lot of casinos to choose from. Time restrictions. 100 casino bonuses often have time limits within which you must fulfil the wagering requirements.
Extended gameplay. Doubling your funds means doubling your playtime. 
Opportunity to explore. You can use your bonus funds to test out different betting types and strategies for free.

There are different kinds of 100 casino bonus offers to choose from. Some casinos offer cash or bonus funds, whilst others offer free spins. If this is all new to you, we’re here to sort it all out.

100 Welcome Casino Bonus

Take advantage of the 100 casino welcome bonus to receive 100% of your first deposit back in bonus funds as a new player. It means that if you deposit £50, you’ll get another £50 to play with. This might come in the form of bonus funds or free bets. The terms often vary based on what site you’re playing at. 

Many of these bonuses come with a cap, so it’s not unlimited. For example, if a casino bonus 100 promotion offers you 100% extra on your deposit, up to £1,000, this means that £1,000 is the maximum bonus you can earn. If you deposit £500, you’ll get £500 on top. If you deposit £1,000, you’ll get £1,000 on top. But if you deposit £1,200, you’ll only receive £1,000 on top.

Best 100 Deposit Bonus Casinos UK

100 Real Money Deposit Bonus

Would you like to get some real money to play with? Then load your account with £100 and get another £100 for free. Real money match bonuses are designed to arm you with extra cash instead of bonus funds, so you don’t have to meet any wagering requirements (though some restrictions may still apply).

Free Spins for a £100 Deposit

If slots are your game, you should consider bonuses that hand you free spins when you load your account for the first time. These bonuses often require a £100 deposit, but you might be able to find free spins with smaller deposits if you don’t want to commit that much. 

💡 A note from Mr. Gamble: Keep in mind that most casinos will only let you pick one bonus when signing up, so if you want free cash and free spins, you might be out of luck.

100 Deposit Bonus Sports Betting

Are you a sports fan? Some betting sites offer 100 deposit bonuses that come in the form of free bets you can use to bet on your favourite sports and sporting events. Simply make a deposit and get a 100% deposit bonus from your chosen bookie. 

How to Withdraw a 100% Casino Bonus?

You won? Go you! Now it’s time to get your hands on your winnings. And it’s super easy to do so. Assuming you’ve met any terms and conditions and completed the playthrough requirements, all your winnings should be in your casino cash account (instead of your bonus account).

Just head to the Cashier, click Withdraw, choose your withdrawal method, and boom. You’ll have your cash sooner than you can spell Saskatoon, Saskatchewan backwards. Well, maybe not that soon, but pretty close.

100% Deposit Bonus Slots & Other Games

A 100 deposit bonus offers you the opportunity to explore various game categories. While some bonuses may be specific to certain game types, often slot games, other online betting sites provide greater flexibility. Here are some of the most common games you can play with a 100% bonus.

  • Slots 🎰 – Slot games are the most popular game type available with a 100% deposit bonus. While some casinos offer this bonus on classic and popular online slots like Book of Dead, Starburst, and Gonzo’s Quest, others have new and upcoming 100 deposit bonus slots available.
  • Table games 🃏 – At some casinos, you can use your 100% deposit bonus on table games such as blackjack, roulette, baccarat, and poker.
  • Live casino ♣️ – some 100 bonuses also extend to immersive live dealer games. Usually, you get to choose from live roulette, live blackjack, and live baccarat, to name a few.
  • Sports betting 🐎  – certain 100% match bonuses may also give you the opportunity to bet on sports. You can use your 100 deposit bonus sports to bet on football, basketball, ice hockey, and more.

New Casinos With 100% Deposit Bonus 

A 100 bonus deposit is a common bonus, and thus, it’s easy to find it at many casinos. This is precisely why new 100 deposit bonus betting sites pop up all the time, giving you even more options to choose from. 

What’s more, new casinos in the UK usually give players 100 deposit bonuses with more favourable terms and conditions in order to compete with more established brands. There’s no room for monotony at Mr. Gamble, and we’re always on the lookout for brand-new casinos we add to our list of recommendations. 

7 Things to Know About 100 Welcome Casino Bonuses

Here are some important things to know about 100 welcome bonuses.

There’s Usually a Minimum

When you make that first deposit, it’s important to be mindful of the minimum amount required. This can vary by online casino and the specific promotion, so make sure you’re meeting the minimum. The casino will state what that number is right on the offer, so you shouldn’t have to go hunting.

There’s Usually a Maximum

While a 100% deposit match seems lucrative, the faucet doesn’t remain open forever. Most of these 100 free casino bonus offers come with a maximum amount. Again, the site will be open and honest about what that is. 

For example, if a casino lists the maximum as £500, that means £500 is the largest bonus you’ll receive on your deposit. If you deposit £25, you’ll get £25. If you deposit £500, you’ll get £500. But if you deposit £1,000, you’ll only receive £500.

It’s Sometimes Paid in Cash

In some cases, the bonus is paid in unrestricted cash, which means you can withdraw it right away without meeting any wagering requirements. These offers are extremely rare and are usually very low in value. 

For example, you’re unlikely to find a £100 casino bonus match, but you might find one valued at £5 or £10. And in some cases, the casino might require that you deposit a lot to get a little. For example, rather than giving you £100 on a £100 deposit, you might get £10 extra on a £200 deposit.

It’s Most Often Paid in Bonus Cash

When you take advantage of a £100 welcome bonus at an online casino, you’ll most likely receive your funds in bonus cash. While you can play with bonus cash right away, you can only convert it to cash and withdraw it once you’ve met the wagering requirements.

Each site offers different wagering requirements (often called rollover requirements), but they’ll spell it out for you so there are no surprises.

Read the Terms & Conditions

The last thing you want to do is be confused about your online casino bonus £100 offer, so be sure to check the terms and conditions to see what they are before loading your account.

Don’t Mix Them With Other Offers

If a site offers a 100% match bonus, it’s important to note that it usually can’t be combined with another promotion. For example, a site might also offer free spins with that first deposit as an option. Always do your research to make sure the bonus you’re choosing works well for you.

Use Your Bonus on All Games

Can’t decide between slots, table games, or video poker? With most 100 casino bonus offers, you don’t have to worry about making the decision off the bat. Unless otherwise stated, you can use your bonus on your favourite game. Of course, there are exceptions to the rules, so make sure you always read the fine print.

Frequently Asked Questions

How to find a 100 percent deposit bonus?

You can find the best 100 deposit bonus offers right here on this page. We’ve done all the research for you and narrowed down our list. Simply select one of the casinos and click ‘PLAY’.

Will I receive other 100% welcome casino bonus offers after depositing?

It's definitely not uncommon to receive 100 match bonus offers after you make the first deposit, although it’s not guaranteed. Make sure you opt into email and SMS messages for the chance to get in on future offers after you’ve made your first deposit.

It’s good to know that most online casinos will look at how much you’re playing, how much you’re winning, and even how much you’re not winning to determine what to offer you.

What are the types of 100 casino bonuses?

You can find a number of 100 casino bonus offers. In some cases, the casino will match your deposit with actual cash. So if you deposit £100, you’ll have £200 in cash to play with (your £100 and the casino’s £100).

In other cases, your deposit match is paid in bonus funds. The bonus is loaded into your bonus account and only converted into cash when you meet the wagering requirements. And some casinos offer free spins as part of the 100 deposit bonus.

Can 100% bonuses expire?

Yes. That’s why you should always read the terms of conditions before taking advantage of any bonus. But you’ll probably spend your deposit bonus before you know it, so even if the bonus came with an expiry date, it’s not something you need to worry about. 

For example, let’s say you deposit £50, and the casino gives you another £50 in bonus funds to play with, there’s a good chance you’ll spend that bonus rather quickly.

How can I claim a 100 deposit bonus?

If you find a 100 casino welcome bonus that appeals to you, just click the ‘PLAY button’ and you will be redirected to the gambling site of your choice. Then, simply follow the on-screen instructions provided by the casino.

The site you’re signing up with knows that we sent you there, so they’ll offer you the exclusive bonus that we’ve negotiated right away.

What are the advantages of 100% bonuses?

These bonuses put you at a major advantage by giving you more bankroll to play with. For example, let’s say you only have £25 to play with but you really want to go big on blackjack. With a 100 match bonus casino offer, you’ll have £50 to play with when you make that first deposit. Pretty neat, eh?

Do casinos offer 200%, 300%, 400% and 500% bonuses?

They exist, but 100 free casino bonus offers are more common. You’ll also find that bonuses with a higher match percentage come with more restrictions. You might need to wager more to turn that bonus cash into real funds that you can withdraw. Always check the terms and conditions before diving in to claim just any offer.

Why are casinos giving away free money?

There’s lots of competition out there. One way to stand out is by offering deposit bonuses to new players. It’s a great way for an online casino to show you how much they value you as a player before you even place your first bet at the slots and tables.
