Different Types of Online Casino Bonus 

Some are undoubtedly more common than others. However, there are a variety of bonuses available to players at online casinos today. It is important to understand the difference between each bonus. Below is a quick breakdown of the online casino bonus offers players in the UK can expect to find:

Matched Deposit Bonus

As you will see from the table at the top of the page, the most common promotion for new customers is a matched deposit bonus. Here, new players will see their opening deposit rewarded by a bonus. This will be 50%, 100% or 200% of your deposit. As such, it can provide players with a large opening kitty. Of course, terms and conditions are found, including wagering requirements, payment restrictions and expiry date. Offering a 100% matched bonus of up to £100 + 100 free spins, 2KBetCasino is one of the many online casinos offering such a bonus. 

No Deposit Bonus

Such bonuses are hugely appealing to players. This is because no financial investment is required. Simply completing the registration process will result in a bonus, albeit a small one. This is likely to be as high as just £20. However, with this effectively being free funds to play with, online casino no deposit bonus offers are well worth taking advantage of. A no deposit bonus worth 88 free spins is available at 888Casino.

Free Spins Bonus

For fans of online slots, free spins bonuses are likely to appeal. Rather than bonus funds, bonus spins are offered by online casinos. For example, Betfred offers 100 free spins to new players depositing £10+. Spins are likely to be available on selected slots, with wagering requirements once again coming into play.

Reload Bonus

For existing customers, reload bonuses are one of the most popular bonuses. Offered to players who deposit over a specific amount in the required timeframe, reload bonuses are available at an increasing number of casino sites. At Genesis Casino, players can earn a 25% bonus worth up to £100 on a Friday.

Which Payment Methods Can I Use For Online Casino Bonuses? 

As you will have read in the table above, some online casinos bonuses come with payment restrictions. This will mean that your preferred method of payment could be excluded from the promotion. In most cases, it is e-wallets that are ineligible. This means that punters looking to add funds via Skrill, Neteller, PayPal or Paysafecard may have to look for an alternative. Of course, having made your opening deposit, you can then switch to your no.1 payment option. With credit cards being banned for gambling purposes in the UK, it is recommended to use a debit card for your first deposit. This will put you in a position to qualify for any online casino bonus that may be on offer. 

Online Casino Bonus Key Terms and Conditions 

Before signing up with a casino, it is important to look at its bonus terms. Terms and conditions will impact both how players qualify in the first place, as well as how they profit from the bonus. Below are some of the most common bonus T&Cs, which players must familiarise themselves with:

  • Minimum Deposit – In order to qualify for an online casino bonus, a deposit will generally be required. Deposits made below this value will not be eligible. So, whether it be £10, £20 or £50, ensure that you add the required funds to your account. Payment restrictions may also come into play. This will impact which payment methods are eligible for a bonus. 
  • Wagering Requirements – Unfortunately, winnings made from a casino bonus will not be available to withdraw immediately. In most cases, wagering requirements must be completed beforehand. This means betting the total bonus amount anywhere from 10x to 50x. Of course, the higher the wagering requirements, the more unrealistic profits will be. 
  • Eligible Games – When using an online casino bonus, players must consider eligible games. Bets placed on other games will not contribute to the wagering requirements. Meanwhile, some games will contribute more to the wagering requirements than others.
  • Expiry – When looking to meet the wagering requirements set, players will have a specific number of days. This can be anywhere from 7-90, with the type of bonus determining the exact period of time. Bonuses that remain after the expiry date will most likely be forfeited.
  • Maximum Winnings – In order to cover their own backs, many online casinos will set maximum winnings. This means that regardless of how much players make from a bonus, earnings will be capped at this amount. This can be as much as thousands of Pounds, with beginners and high rollers normally catered for.

How To Profit From Online Casino Bonuses 

No matter how good the bonus is, there are no guarantees that a profit will be made from it. However, there are steps which players can take to increase their chances of success. The following are our top 5 tips for profiting from an online casino bonus:

  1. Check the T&Cs – Before claiming any casino bonus, be sure to read the small print. There is nothing worse than being surprised by the high wagering requirements or payment restrictions after signing up and depositing. 
  2. Wagering Requirements Contribution – Different games will contribute varying amounts towards the wagering requirements. For example, slots may contribute 100%, while live dealer titles may only contribute 10%. Such facts will have a major impact on how quickly you can unlock bonuses.
  3. Low Variance Slots – Low, or even medium, variance slots are well worth playing with bonuses. While the size of the wins here may not be large, the number will appeal to newcomers. Such games make reaching the wagering requirements all the easier. 
  4. Track Your Progress – It can be easy to get carried away when using a casino bonus. However, rather than placing bets at will, be sure to regularly check on your progress. Doing so will allow players to see how close they are to reaching the wagering requirements. 
  5. Forfeit the Bonus? – It may sound crazy, but in some cases, it is actually better to forfeit the bonus. Most players will bet with real money first, rather than bonus funds. In the event of winning big with your own money, it could be worthwhile withdrawing immediately, thus forfeiting the bonus.

How To Sign Up For An Online Casino Bonus 

It is nice for players to have an understanding of how to claim an online casino bonus before getting started. Using the bonus from 2KBet Casino as an example, the following step by step guide will help players on their way:

Step 1: Register an Account

Having selected the bonus that best suits your needs, it is time to register an account with the casino in question. Whether it be via desktop, mobile or tablet, enter the website of the casino. Click or tap on the “JOIN NOW” button. Complete the registration form by entering the required personal details. At this point, also create a password for your account. Click or tap “Submit” in order to confirm. Verify your account via email to complete the sign-up process.

Step 2: Deposit Funds

Login using your username and password. Enter the cashier page, before selecting the “Deposit” option. Select an eligible payment method from the list provided. Enter the amount, ensuring that you hit the minimum deposit requirement. If a debit card is selected, enter the card details, including expiry date and CVV code. Confirm the transaction and wait a few seconds for funds to appear within your account.

Step 3: Claim Bonus

Within 48 hours of making a qualifying deposit, the amount will be doubled in the form of a bonus. For example, if you deposited £20, your opening balance will be £40. If you have not received your bonus within this timeframe, contact the casino’s customer service team.

Step 4: Place Bets

Place bets using your bonus in order to meet the wagering requirements. Look at which games are eligible, as well as how different titles contribute more to the wagering requirements. At 2KBet, this is 50x the bonus amount.

Step 5: Withdraw Winnings

Once you have met the wagering requirements, withdrawals will be available, should you have money left. When ready, enter the cashier page again, this time selecting the “Withdraw” option. It is recommended to use the same payment method for deposits and withdrawals. However, if you wish to use an e-wallet to speed things up then that is allowed.

Bottom Line on Online Casino Bonus Offers

When the terms and conditions are realistic, there is little doubt that an online casino bonus can be hugely rewarding for players. The majority of bonuses are reserved for new customers. However, reload and cashback bonuses help to keep existing customers satisfied too. Be sure to check out our top ranked offers, each of which comes from a licensed and fair online casino.
