Best 100% Casino Bonuses

It’s safe to say that 100% Deposit Bonuses are the most popular bonus in the online casino world. This welcome bonus will greet you at many UK online casinos and promise to double your money!

You might be a first-time player, accessing an online casino for the very first time. Or, perhaps you're a seasoned player, looking for that new casino to explore. For some players, bargain hunting for 100 casino bonuses is an activity in itself, trying to find that sweet deal that will get you double your playing funds.

As enchantingly brilliant as a 100 bonus sounds, finding the right deal for you, amongst a myriad of bonuses on offer in the increasingly dense online casino space, can be quite tricky. You can easily be overwhelmed by the heap of offers thrown at you. The numbers, the percentages, the terms and conditions - what do they all mean and how do you choose the best 100 bonus at a casino?

Luckily, we’re here to help! Here's what we've got in store for you:

Casino Deposits

What is a 100% deposit bonus?

Deposit bonuses for new players come into effect when you deposit your initial funds at an online casino. In its simplest form, a 100 casino bonus will match your deposited funds by 100%, essentially doubling your money.

So, if you had to deposit £20, the casino would match your money and give you another £20 on top. These bonus funds awarded by the casino are generally kept separately from your deposited funds. Additionally, they are paid in the form of bonus money, which comes with its own set of advantages and constraints, but we’ll talk more about this later.

Why choose a 100% casino bonus?

So, why would you want a 100% casino bonus? Well, apart from the obvious advantage of getting free money, a casino 100 bonus can serve a very useful purpose in any online casino player’s books.

With your 100 match bonus, you can go on a free tour of your new casino. At any new gambling site, you’ll want some first-hand play time to get a feel of what this new casino’s features include.

Even though you can read a review, it's not the same as playing for yourself. You can have extra time to discover what slots the casino has, from which game developers, and what the overall experience will offer you.

By doubling your initial deposit, you’ll be able to continue playing should fate’s cruel hand rob you of your deposited funds. Normally, you will play with your cash funds first and, if you lose, you’ll have your bonus money to keep you covered.

At this point it’s worth mentioning that at most online casinos, your bonus funds will have a wagering requirement attached to them, meaning you will have to wager your bonus amount a certain number of times before you can make a withdrawal.

So, you should really look for casinos that keep bonus money and real money in separate wallets. By having the bonus money separated from your deposited funds, you will make sure that your personal funds are not subject to the same wagering requirements that are imposed on your bonus money. This is because your bets won't be made with a mix of cash and bonus funds.

How to claim a 100% bonus?

By now you must be thinking, that’s all well and good, but how do I actually get one of these 100 no deposit casino bonuses? Not to worry. We’ve outlined the simple process in a few easy-to-follow steps that you’ll be able to complete within just a few minutes:

  1. Firstly, we have compiled a list of the top UK casinos with 100% bonuses so you can easily pick the offer which appeals the most to you.
  2. Now, sign-up to the casino. Fill in all of your details and complete the registration form.
  3. Next, you will need to make a deposit. The amount you top up will need to meet the minimum requirements.
  4. Once your deposit is confirmed, your money will be doubled!

Eligibility for 100% bonuses

There are terms and conditions that come with all casino bonuses out there. These Ts and Cs will vary according to each bonus offer and will generally outline who is eligible to claim the bonus. Here are some things you can check to ensure you aren't left out:

  • The bonus might only be for new players; you won't be able to sign up again with a different email address to get the bonus twice. 
  • You might not be able to claim the bonus if you deposit through a certain payment method (such as Neteller or Skrill). 

100% Bonuses - Are They Only for New Players?

So, we’ve gone through the basics of what a 100% casino bonus actually is, but are these offers exclusively available for new players? What if you're an avid online player, who enjoys their casino of choice and you have no intention of switching to another? Does this mean that you’ll never be able to take advantage of these match bonuses?

While most 100 casino bonuses are generally welcome offers for new players, certain casinos have VIP and Loyalty Programs which give perks to regular players. These perks include Reload Bonuses which players can get when they make a ‘reload’ deposit. Sometimes, you will have to deposit on a certain day or play on a selected game to enjoy this sort of bonus.

Casino Bonuses

Wagering & Max Cashout on a 100% Bonus

All this talk of 100% Bonuses can sound pretty enticing, but there are a few conditions and limitations that apply to these bonus funds given by the casino. Let’s have a look at some of these restrictions and explain exactly what they mean for you as a player:

  • Maximum Bonus Amount:
    The casino may agree to match your deposit at 100% but that doesn’t mean that you can deposit any amount you wish and get a guaranteed duplication. Casinos place limits on these bonus offers, meaning that they will only double up to a certain amount. A common bonus offer will read something like: ‘100% Deposit Bonus Up To £100’. This means that the casino will match your deposits up to £100. Any amount you deposit over £100 will not be matched. So, if you deposit £200, you will still only get an additional £100.
  • Wagering Requirement:
    You’ll often find a condition that looks like this, ‘50x Wagering Requirement’. This wagering requirement is basically a multiplier that identifies the number of times you have to play through a bonus before you will actually be able to withdraw any of your winnings. So, if you claim a £10 bonus with a 15x wagering requirement, you’ll have to play or 'wager' £150 before you can make a withdrawal. Note that not all games count towards the wagering requirements so double-check before you start wagering on a particular slot or casino game.
  • Max Cashout:
    This refers to the maximum amount that you can withdraw from playing with the bonus. Even if you win when playing with your bonus money, and you manage to wager it, you might not be able to claim all of it. Anything you win and convert into cash (through completing the wagering requirements) over the max cashout limit will be forfeit.
  • Max Bonus Bet:
    This is the maximum amount you can place or wager on a game in a single bet when playing with bonus money. Normally, at UK casinos, this is set at somewhere around £5. Casinos implement max bet limits to ensure players can't take advantage of bonuses and wager them unfairly by placing large bets.
