Best Casino Bonuses
This list shows the biggest casino bonuses in the UK. These bonuses are more than the usual 100% deposit match bonus. E.g Deposit £10 get £10 bonus (£20 in total to play).
If you want to deposit smaller amounts, check our £5 deposit page. You can still get the bonus with this smaller deposit.
Changing Landscape of Casino Bonuses: CMA Scrutiny Prompts Shift in Online Casino Strategies
The whole world of bonuses is getting a bit unpredictable at the time of writing. The Competition and Markets Authority (CMA) in the United Kingdom is closely monitoring online casinos. They are paying attention to the Terms and Conditions that these casinos use. They have taken action.
This has resulted in quite a few changes in the company’s strategies when it comes to planning bonus offers. The situation is still changing as I write this. Right now, no one can be sure how it will turn out.
The bonuses offered by online casinos have traditionally revolved around deposit bonuses or free spins. Both involve players making a real cash deposit, which is then topped up by the site promoter. This is often in the form of matched funding.
You deposit £10, supplemented by an additional £10 bonus cash to spend on the site. Sometimes, if the site operators want to attract new players, the bonus can be higher. You might deposit £10 and receive £20, £30, or even more in bonus money.
But no matter how tempting the offer, there is always a catch. For casino players, the catch is the wagering requirements. These are often hidden deep in the long pages of the site’s Terms & Conditions. The CMA is indeed also very interested in these.
Understanding Wagering Requirements: Variations by Game Type and Time Limits on Casino Bonuses
Players must spend a certain amount of their money before withdrawing any winnings. This amount is always expressed as a multiple of the original bonus and sometimes the suggested deposit. The actual multiple varies from site to site but is generally around 30 x and can be as much as 50 x. You do have to look at the actual terms quite closely to work out the best deal.
For example, 50 x your bonus can be a better deal than 30 x your bonus + deposit. To take the above illustration: 50 x £10 bonus = £500, but 30 x £20 (£10 deposit + £10 bonus) is £600. Remember that you may have to spend this much of your own money before you are permitted to make a claim.
These spending requirements apply only to play on regular slots. If you decide to spend your money on premium slots or tabletop games like poker or roulette, the requirement will be much higher.
This is because only a tiny part of your spending on these games helps meet the wagering requirement. There is also usually a limit on how much time you are allowed to spend this amount. It can be up to 90 days but is frequently as little as a month.
Sometimes, the site offers free spins instead of or in addition to your deposit bonus. See our Free Spins page for more details on this kind of promotion.
But in either case, rest assured: we’ll keep an eye on all this whenever we find a new casino offering NetEnt games. We’ll also tell you where the best deals are and outline the relevant wagering requirements. Remember, though, that these are liable to change, so it’s always best to check for yourself before signing up. And with the Competition and Markets Authority on the case, these changes may happen more often than ever.
