Updated: In a time not so long ago, the online casino space was dominated by a select number of established players. This meant that casinos were not overly motivated to offer lucrative welcome bonuses, as competition was rather thin. However, fast forward to now and the online slots space is now over-saturated. This means that bonus package offers are getting more and more competitive, with heaps of 200% casino bonus offers now in circulation.

If you’re here reading this because you are looking for a casino 200% bonus yourself, then you’ve certainly come to the right place. We at BestRatedSlotSites.co.uk have compiled the ultimate list of bonus-rich online gambling sites that we think you should consider. Moreover, if you’re wondering how 200% bonuses actually work, we welcome you to read our in-depth guide.

Let’s start by exploring what a 200% casino bonus actually is.

What is a casino bonus 200%?

In its most basic form, a 200 percent deposit bonus is what we would refer to as a ‘Match Deposit Bonus’. This means that the casino will ‘match’ your deposit by a certain percentage, up to a certain amount. Back in the early days of matched bonuses, casinos would usually match your bonus by 100%. This amounted to a like-for-like deposit boost. For example, if you were to deposit £100, then the casino would give you an additional £100 on top.

However - and as we noted just a moment ago, players are no longer content with a simple 100% boost. Instead, they are seeking casinos that are looking to go one step further. As such, the new breed of matched deposit bonuses comes in the form of a 200% deposit bonus.

Here’s how it typically works.

  1. You join a new casino that offers a 200% welcome bonus UK up to £200
  2. The £200 refers to the maximum bonus funds on offer, not the deposit amount.
  3. As such, you decide to maximize the offer by depositing £100.
  4. In return, the casino gives you an additional £200.
  5. This means that your casino starting balance is £300, even though you only deposited £100!

Once the bonus has been claimed, the funds will then be added to your ‘bonus balance’. As we will discuss in more detail further down, you won’t be able to withdraw your 200% welcome bonus out until you meet the wagering requirements outlined in the terms of the offer.

How do I claim a 200% deposit bonus?

In the vast majority of cases, you will not be required to do anything to claim the bonus, as it will be applied to your account as soon as you meet the qualifying condition. In this sense, the qualifying condition is simply making a deposit. For example, if the bonus stipulates that you need to deposit between £10 and £200 to get the bonus, the funds will be added to your balance as soon as you do this.

In other cases, you might need to enter a special bonus code to get the 200% offer. You will either find this displayed on the casino’s homepage, or within the terms of the offer. Either way, we at BestRatedSlotSites.co.uk will let you know if you are required to enter a promo code.

In rare cases, if you are confident that you have met the qualifying condition, but the 200% casino bonus has not been credited, then you might need to speak with customer support. The easiest way to do this is to speak with an agent via live chat. Once you have explained the situation, they are likely to credit the bonus funds on the spot.

Are 200% casino bonuses a scam?

As the old saying goes - “If it’s too good to be true, it probably is”. However, this couldn’t be further from the truth in the case of a 200 percent deposit bonus. On the contrary, they work much in the same way as any other bonus.

The reason that some of our readers are skeptical about new casino 200% bonus offers is because of the sheer size of the giveaway. While this is somewhat true, you have to remember just how valuable you are to the casino.

With literally thousands and thousands of online slots sites now in operation, winning new customers has never been more difficult. As a result, online casinos have no choice but to up the ante, and subsequently, increase the size of their casino offers.

Casinos understand that while they might lose money in the short-run, they hope that you remain on the platform long-term once the bonus funds have been consumed. All-in-all, 200% sign up bonus offers are completely legitimate.

200% casino bonuses: Terms conditions (conditions apply)

While there is no question regarding the legitimacy of 200% casino bonuses, this isn’t to say that you are simply getting ‘free money’. On the contrary, each bonus will come with a set of terms and conditions that you must be fully aware of prior to signing up.

These typically remain constant across the board, so we’ve outlined the key fundamentals that you need to look out for below. 

Wagering requirement

The biggest thing standing between you and the ability to withdraw your 200% casino bonus funds is that of the wagering requirement. In a nutshell, this is the amount of times that you need to gamble the bonus fund through before you can cash them out. The wagering requirement will always be expressed as a multiple, which you then need to multiply against the size of the bonus. Check out of detailed guide on low wagering casinos and their bonuses to learn more.

Let’s take a look at a quick example so you understand how the wagering requirement works in practice.

  1. You claim a 200% welcome bonus of £100
  2. The bonus comes with a wagering requirement of 20x
  3. This means you need to bet 20 times the bonus
  4. As 20 x £100 is £2,000, you need to gamble at least £2,000 at the casino before you can withdraw the bonus funds out
  5. Once you do, you are free to withdraw your entire bonus balance

Min/Max deposits

On top of the wagering requirement, you will also need to look at the minimum and maximum deposit amounts. Regarding the former, this is the minimum deposit amount that you need to meet in order to get the 200% casino bonus credited. If you don’t, you won’t meet the qualifying condition.

When it comes to the maximum deposit amount, this refers to the maximum bonus amount that will be credited - not the maximum amount you can actually deposit.

For example, let’s say that you claim a 200% casino offer that comes with a maximum bonus amount of £300. This means that by depositing £150, you would get the maximum bonus amount of £300.

However, if you were to deposit £500, you would still only get a £300 bonus. Albeit, your starting balance would be £450 in bonus funds (£150 qualifying deposit + £300 bonus) and £350 in real money funds (the balance).

Time limit on bonus

You will also need to make some considerations regarding the time limit of the 200 percent casino bonus. This will come in two forms. Firstly, you will have a time limit to actually claim the bonus from the time the account was opened. For example, you might get 7 days to make your qualifying deposit once the registration process has been completed. If you don’t, you won’t be eligible for the 200% welcome bonus casino offer.

Secondly, you will also have a fixed number of days to meet your wagering requirement. Failure to reach your target within this time-frame will see the bonus funds revoked.

Game contribution percentages

The final - and equally as important condition that you need to assess is with respect to the game contribution percentages. In plain English, these are the games that you can play to meet your wagering requirement. When you scroll through the terms, it should let you know what percentage each game contributes.

In the vast majority of cases, 200% welcome bonus slots will contribute the full amount. For example, if you gamble £20 per spin, each spin will then knock off £20 from your overall wagering target. However, other casino games will all-but certainly contribute less.

We often find that the likes of roulette, blackjack and other table games will only contribute 10% towards the target. For example, if you played a hand of blackjack at £200, only £20 would be knocked off from the wagering target.
