Find the Best 100% Deposit Bonuses at JohnSlots!

If you want to play at online casinos with only the best 100% deposit bonuses, we have an expert casino team behind JohnSlots looking for just that. They have an extensive list of criteria to follow. Only deserving casino sites that tick the right boxes reach our high-quality top list. Here are just a few criteria we use to find, compare and judge the 100% deposit bonuses that you’ll find on this page:

WHAT WE LOOK FORWHY
Minimum DepositWe are always keen to find casinos with deposit bonuses that are accessible to both experienced and new players. For example, bonuses with a smaller minimum deposit such as £5 or £10 offer far more incentive than to start with than the higher minimum deposit bonuses.
Max Bonus AmountWe want our recommended online casinos to appeal to a wide range of players. That’s why we are always on the lookout for bonuses with higher cash amounts. In our extensive casino library you’ll find deposit bonuses of 100% up to £50, £100 and even £500.
Game EligibilityOne of the best things about the 100% deposit offer is the ability to test some of the most popular games and new titles for free with bonus money. Therefore, we look for online casinos that can provide a good variety of high-quality games that you can play using the bonuses.
Wagering RequirementsWe strive to ensure that our recommended sites have fair and, where possible, low wagering requirements so that you can get the most value for your money. We’ll always flag it up if the wagering requirements are too high.

Best 100% Casino Bonuses

On this 100% bonus page, you will find:

What Is a 100% Deposit Bonus?

A 100% deposit bonus, also called a match bonus, is perhaps one of the most common deposit bonuses at UK casinos. It’s bonus money equal to the amount you deposit. You receive the funds after you register with the casino as a new UK player and complete your first deposit. When claimed, your bonus money appears in a separate wallet from your real money. You can use it after you spend your real cash. So, if you’ve lost on a game using your actual money, you have a second chance to win and play for longer with your bonus funds.

Advantages of 100% Casino Bonuses

Why Choose a 100% Casino Bonus?

There are many advantages to choosing an online casino with a 100% deposit bonus. You get your deposit instantly doubled giving you a chance to extend your gameplay. Using a deposit bonus, you have a second chance at winning even after losing your real money deposit.

Another good reason for choosing a 100% bonus is the lower wagering requirements compared to a higher percentage bonus. A 200% or 300% deposit bonus will give you a more bonus money, but most likely, it will also have much higher wagering attached to it.

But the best thing about a 100% deposit bonus, as opposed to a free spins only offer, is that a match deposit bonus includes bonus cash which you can use on a variety of games. Not just on slots, but also table games, video poker, scratch cards and maybe even live casino games. Though, most of the time, live dealer games will have a separate deposit bonus offer for you to claim.

How to Claim a Welcome Bonus

How to Claim a 100% Bonus?

If you are interested in signing up to a casino and doubling your first deposit, follow these steps:

  1. Find a casino with the 100% deposit bonus offer (use our list for the best recommendations!),
  2. Create a new account with your chosen site,
  3. Check the terms and conditions of the bonus,
  4. Claim your bonus by making the first minimum deposit,
  5. Enter the bonus code, if required,
  6. Start playing the eligible games to activate the bonus,
  7. Use your bonus funds to fulfil the wagering requirements,
  8. Once the wagering is complete, withdraw your remaining bonus funds in real money using your preferred payment method.

Eligibility for 100% Bonuses

When you think you found the right casino to claim your 100 casino bonus, you should always take your time to check the bonus terms and conditions attached to the offer. Most, if not all, casino bonuses come with the significant terms. These will be visible within the initial bonus advert. These T&Cs will state the most immediate requisites regarding eligibility. They can include the following:

  • New players only – this means that if you already have an account with this casino, you are no longer eligible for the new-player deposit bonus.
  • 18+ – only players 18 years old or over can claim the bonus.
  • UK players only – you can only claim the advertised 100% bonus if you reside in the UK.
  • Skrill/Neteller deposits excluded – the rule excluding Skrill / Neteller players from bonuses is becoming more and more common in the UK due to strict compliance regulations enforced by the Gambling Commission. If that’s the case at your chosen site, you can still deposit using a different payment method such as a Visa card or another e-wallet accepted by the casino.

100% Bonus – Only for New Players?

100% welcome bonuses are reserved for new players only who can meet the terms of the welcome offer, i.e., are 18+, live in the UK and haven’t already had a verified account with the casino. However, if you are a returning customer, you may benefit from a reload bonus.

To keep existing players happy, many online casinos offer a 50%, or a 100% reload bonus from time to time. Depending on the casino’s promotion, you can activate these match bonuses by depositing more money into your casino account. If they are part of a welcome package, you might be able to get 50% or 100% matches on your first five deposits!

You can often find reload bonuses available to all existing players, but sometimes these will only be accessible to high rollers or VIPs.

VIP schemes vary from casino to casino. Some are by invitation only, others come as a multi-tiered setup, but all require you to play for real money to join. So, the more you wager real cash, the better chances you have to enter the VIP program and benefit from exclusive promotional offers. Always remember to gamble responsibly.

One other way to always be in the loop is to join the casino’s newsletter or opt-in to receive their promotional alerts. This way you’ll always be the first to know about the casino’s latest bonus offers.

Wagering & Cashout on 100% deposit bonuses

Wagering & Max Cashout on a 100% Bonus

One thing that you’ll always want to check out before claiming a 100% bonus is the wagering requirements. It’s the amount of cash you’ll have to play through before you can withdraw any of your winnings. The wagering requirement varies from casino to casino and can be anything from 10% to 80% and higher. As a rule of thumb, the lower the wagering requirement, the better the offer. Even better are no wagering offers!

A max winning cap or cashout limit is another restriction that will impact the quality of your 100 casino bonus. It indicates the maximum amount you can withdraw from playing with your bonus. Anything you win over this amount will be forfeit. So, naturally, you’ll want to look for bonuses that have a higher winning cap wherever possible.

Now that you know what to look out for in a 100% deposit bonus, you’ll need to check which withdrawal options are accepted. Most commonly, you can use bank cards, bank transfer, e-wallets, or the pay by phone method.

Withdrawal timings can also vary depending on the casino or payment method. They can take from 2-5 days for bank cards and from 24h to 2 days and upwards for e-wallets. Usually, casinos don’t have much control over the bank card withdrawals and, therefore, these take much longer to process than the e-wallets.
