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. In other words, you get 100% extra (or double) your deposit.

For example: if you make a deposit of €10 and claim a 100% deposit bonus, you’d receive €10 in bonus funds, giving you €20 total in your casino balance to play with.

Typically, players will find two balances on their accounts. You’ll find your actual deposit and your bonus balance. Casinos have specific T&Cs that cover the use of these balances, particularly which one is used first when you play.

100 Deposit Bonus Terms and Conditions

Before you claim your reward 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

How to Claim a 100% Casino Bonus

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

Pros and Cons of 100% Deposit Bonuses

A 100% casino bonus doubles your deposit, but is it really worth it? We break down the real pros and cons of this popular offer so you know exactly what you’re getting before you claim it.

✔️ PROS❌CONS
Easy to find. A 100% bonus is the most common match bonus out there, so there are a lot of casinos to choose from.Wagering requirements. Most 100% bonuses come with playthrough requirements, so you cannot cash out your bonus money before wagering.
Extended gameplay. Doubling your funds means doubling your playtime.Time restrictions. 100% casino bonuses often have time limits within which you must fulfil the wagering requirements.
Opportunity to explore. You can use your bonus funds to try different slot games and features for free. Qualifying games. Not all casino games contribute equally to the playthrough requirement.
Flexibility. Sometimes you can use your bonus to play a variety of slot titles instead of being limited to just one, though it all depends on the specific bonus offer.Allowed deposit option. Some casinos may restrict the use of Skrill and Neteller in qualifying for the 100% deposit bonus.
Extra free spins. Sometimes, casino operators bundle extra spins with their 100% match bonus. 

Mobile Casinos With a 100% Deposit Bonus 

In this day and age, almost any casino with a 100% deposit bonus is optimised for mobile play. More of us than ever choose to play on our phones, and online casinos have quickly adapted to meet that demand.

Claiming a match bonus on mobile feels seamless — you can sign up, deposit, and start playing in just a couple of taps. What makes it even cooler is when the 100% deposit casino site has a blisteringly fast mobile app. No lag, no clunky menus, just smooth gameplay and instant access to your bonus wherever you are.

A 100% casino bonus always doubles your deposit, but not all bonuses work the same way. Some casinos offer cash or bonus funds, whilst others offer hybrid bonuses with free spins. 

If this is all new to you, here’s a quick breakdown of the different types you might come across and how they can vary.

100 Welcome Bonus

If you’re a regular at top online casinos, then you’ve encountered the popular 100% welcome casino bonus. The idea is simple: double your first deposit with a 100% free sign-up bonus to boost playing funds. 

Some casino sites offer welcome packages, where a deposit match may be spread over a few days and bundled with free spins. This makes these 100% welcome treats some of the best offers, especially if you’re exploring a new game library.

The most popular types of 100% deposit welcome offers include:

Deposit €5 Get 100% Bonus

Match your €5 deposit with a 100% casino welcome bonus up to €5 – it’s an ideal start, especially for beginners. By doubling the initial deposit, players get a bigger bankroll to try more games. 

However, it’s subject to a few crucial T&Cs, including wagering requirements, game restrictions, and time limits. Typically, 100% bonus casino sites impose a 20x to 40x wagering requirement for the bonus, so your €5 bonus might require you to wager €200-€400 before cashing out.

Deposit €10 Get 100% Bonus

Among the different deposit bonus variants, the ‘deposit €10, get 100% bonus’, is by far the most popular. It’s available to all new players, where operators double your €10 deposit to €20, giving you more playtime, but wagering conditions apply. This 100 percent deposit bonus is a great way to explore casino games without committing too much funds. 

Pay attention to the site’s bonus cap and wagering, which are set at €50 or €100, and 30x to 40x wagering on the bonus, respectively. 100% welcome bonus casino sites are also strict when it comes to eligible games and bonus validity, with some operators just allowing a day to complete the requirements.

Deposit €20 Get 100% Bonus

The promotion ‘deposit €20, get 100% bonus’ is another popular promotion in gambling sites. You’ll frequently find this offer targeting new players, and they’re bundled with additional perks like bonus spins and bigger match bonuses. 

Most of these offers cap the bonus at around €100, though some go up to €200 or more. That means your €20 deposit comes with an extra €20 in bonus funds, doubling your starting balance to €40 for play, but remember the bonus portion is subject to wagering requirements.

If the offer also includes 50 or 100 free spins, it’s an even better kickstart to your casino experience.

100% Reload Bonus Offers

The casino’s 100% reload bonus is available to the site’s existing players, after successfully claiming the welcome promotion. These are deposit match reloads, which aim to reward the existing players. So, when this promo becomes available, it doubles your deposit, giving you extended playing sessions. 

And since it’s a regular promotion at most casinos, you’ll end up with a bigger bankroll every time you top up your account. Reload bonus offers also cap the bonus at a certain amount, and they're often smaller than the typical welcome bonus.

Hybrid Welcome Bonuses

Hybrid welcome bonuses combine a 100% match deposit bonus and extras like free spins. For example, you deposit €30 and receive a €30 bonus plus 50 free spins playable on qualifying slot machines. Some casinos even offer free spins with smaller deposits, making them accessible to more players.

In our observation, these free spins are often playable on players’ favourites such as Pragmatic Play’s Big Bass Splash and Big Bass Bonanza, and Play’n GO’s Book of Dead and Legacy of Dead. The eligible slot with a welcome bonus of 100% (or several slot games) should always be mentioned in the bonus T&Cs.

In a hybrid welcome bonus, pay attention to the terms that apply to the match bonus and free spins. In a match bonus, you’ll need to consider the wagering, eligible games, and validity. And for the bundled free spins, keep an eye on qualifying slots and spin value amount.

High Roller 100% Deposit Bonuses

A high roller 100% deposit bonus is an exclusive promotion designed for casino players who deposit large sums, at least €1,000. Unlike the standard signup promotion that caps your bonus at €100 to €200, a high roller bonus often awards up to €5,000 or more. 

Our research shows this bonus is a staple at many online casinos targeting high-rollers, or ‘big whales.’ These players are consistently drawn to offers that reward larger deposits and higher-stake play.

Bonus Codes for 100% Bonuses

In some  casino sites, bonuses require a specific promotional code to qualify or activate a bonus. A bonus or promo code is a string of letters, numbers or characters, such as ‘FREE10’, which you need to submit to qualify for a promotion. 

In our experience, this code must be submitted upon registration or when making the deposit. However, players must always verify the correctness of the code and its validity. Also, these 100% match bonuses are often tied to exclusive offers with higher wagering terms.

Best 100 Deposit Bonus Casinos

How to Withdraw a 100% Casino Bonus?

With a deposit bonus of 100%, you can’t withdraw right away – you first have to meet the wagering rules. These are expressed as a multiplier, like 10x, 20x, or 35x. 

The key is whether the multiplier applies only to your bonus funds and only your winnings from the bonus need to be wagered, or to both your deposit and bonus, which increases the total wagering required.

For example: You deposit €100 and receive a €100 bonus (35x wagering)

  • If wagering applies to the bonus only: €100 × 35 = €3,500 in wagers required
  • If wagering applies to deposit + bonus: (€100 + £100) × 35 = €7,000 in wagers required

The trick to wagering your 100% casino sign up bonus? Always check the terms to see which method the casino uses. Bonuses with wagering on the bonus only are far easier to clear.

100% Deposit Bonus Slots & Other Games

A casino 100% deposit bonus gives you extra room to explore different game categories. Some offers might be tied to specific games, often slots, while others give you more flexibility across the site.

When claiming your 100% deposit bonus, it’s essential to know which games are eligible and how they contribute to meeting the wagering requirements – unless you’re playing at a no wagering casino, where winnings can be withdrawn without meeting playthrough rules.

Here are some popular game types you can play with a match bonus at a 100 bonus casino:

Slots

Slots are by far the most popular option at 100% sign up bonus casino sites — not just because they’re fun and varied, but also because they usually contribute 100% toward wagering requirements. So, it’s the best way to quickly achieve the required playthrough. 

If you’re playing with a 100% deposit casino bonus, spinning the reels is often the most efficient path to unlocking your winnings.

Just keep in mind that some 100% deposit match casino sites exclude jackpot and progressive jackpot slots from contributing to wagering requirements.

Table Games (Blackjack, Roulette, Baccarat)

100 casino bonus offers online

Some 100% deposit bonuses aren’t limited to slots – at certain casinos, you can also use them on table games like blackjack, roulette, baccarat, and poker, giving you the chance to enjoy a more strategic style of play.

However, they aren’t helpful enough in satisfying the playthrough requirement. In most cases, table games contribute 5% to 10% toward wagering requirements. Of these, roulette is the game most commonly included in bonus-eligible play, so most likely you will be able to enjoy this 100% deposit game for real money.

Live Casino Games

Live casino games, like Crazy Time, Monopoly Live, and Lightning Roulette, offer real-time gameplay, but are not bonus-friendly. They are rarely included in standard 100 percent match bonuses on applicable games. But, when they’re included, they usually have a 0% to 10% wagering contribution. 

Instant Win & Scratch Cards

Instant win games, like scratch cards and arcade-style games, are often included in the eligible games for 100% percent match bonus play (because they have fixed odds). Usually contributing 100% toward wagering requirements, these games are ideal for quick and simple gameplay.

New Casinos With 100% Deposit Bonus 

Many new casinos offer 100% deposit bonuses, often with better terms to compete with bigger brands. These match offers give you more choice and value as a new player.

Below, you’ll find the best new online casinos with generous 100% deposit bonuses:

How to Maximise Your 100% Welcome Casino Bonuses – Mr. Gamble's Tips

If you’re claiming a casino 100% sign up bonus, these tips can help you stretch it further and improve your chances of turning it into withdrawable cash.

Watch the minimum deposit requirement

When claiming your first deposit bonus, always check the minimum amount needed to activate it. This requirement varies depending on the casino and the promotion, but it will be clearly stated in the offer details. Make sure your deposit meets that threshold, otherwise, the bonus won’t be applied.

Know the maximum bonus limit

While an online casino 100% welcome bonus seems lucrative, every 100% casino bonus  comes with a cap. Again, the gambling site will be open and honest about what that is. 

For example, if the offer says ‘up to €500,’ that means €500 is the maximum bonus you can receive on your deposit. 

So if you deposit €25, you’ll get €25. If you deposit €500, you’ll get €500. But if you deposit €1,000, you’ll still receive €500.

Check the wagering requirements

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 100% casino welcome bonus comes with its own wagering requirements (often called rollover), usually between 35x and 50x. The good news is that many offers now lean toward the lower end of that range (below 30x), making them much fairer and easier to clear.

Read the terms & conditions

The last thing you want to do is be confused about your online casino 100 deposit bonus. Be sure to check the terms and conditions so you know exactly how the bonus works and what to expect before loading your account. 

Always check the wagering requirements, eligible games, time limits, and any max withdrawal requirements. Knowing these details upfront helps you avoid surprises, and this way, you get the best value from your casino reward.

Stick to one bonus at a time

When a site offers a 100% match bonus, it usually can’t be combined with another promotion. In many cases, casinos allow only one welcome offer per account, so you may need to choose between the match bonus or an alternative, such as free spins on your first deposit. 

That’s why it’s important to read the details carefully and compare your options. Once you’ve claimed a welcome bonus, you typically won’t be able to switch later.

Use your bonus on the right games

Not sure whether to spend your bonus on slots, table games, or video poker? Good news: unless the bonus says otherwise, you’re free to choose. But here's why slots often make the most sense. Slot games typically contribute 100% toward wagering requirements, meaning every euro you bet counts directly toward clearing the bonus.

Frequently Asked Questions

What does 100% deposit bonus mean?

A 100% deposit bonus is a popular casino offer that doubles your deposit.

Is there a minimum deposit requirement for me to claim a 100% deposit match bonus?

Yes, most 100% first deposit bonus casino sites require a minimum deposit of €10.

What are the common terms and conditions that I must consider when claiming a 100% deposit match bonus?

Aside from the minimum deposit amount, consider the bonus wagering requirement, validity, and eligible games.

Can 100% first deposit bonus​​ offers expire?

Yes. That’s why you should always read the terms and conditions before taking advantage of any bonus. Most casino bonuses also come with an expiry date – often 7, 14, or 30 days – so you’ll need to meet the wagering requirements within that time to keep your winnings.

What games can I play with the 100% casino bonus?
