Best online casino bonuses in the UK

If you are looking for the best online casino bonuses in the UK, then you are in the right place. In this article, we've collected the biggest and most generous casino bonuses from reliable casino operators that offer a full range of online slots and casino games. 

But what defines the best casino bonus? There is probably no "one size fits all" answer here, because different players look at different factors. For some, the maximum full amount of the welcome bonus will be the most important factor, while the others will look at the percentage of the match bonus instead. Other players might be more attracted to a bigger number of free spins or an online casino with low wagering requirements.

Below we've collected a few of the most attractive casino welcome bonuses that will satisfy all different tastes, budgets and preferences of online casino players. Click on the casino links to get the exclusive bonus that you find the most attractive.

Welcome bonus with lowest wagering requirements - Videoslots Casino

While free spins sometimes come completely free from any wagering requirements the actual bonus money always have to be wagered a few times. The difference here is that some casinos have wagering requirements of x40 - x45 times or even higher, so it's worth looking for an online casino that has a way lower rate than that. Videoslots casino is one of those places. Not only you can get a 100% matching bonus up to £200 with only x20 wagering requirements which is lower compared to many other UK casinos. This casino is also known for the biggest, ever-growing selection of slots and casino games. Their portfolio currently has over 2,100 games in total, including slots with high RTP!

Best online casino bonus for slot rewards - PlayOjo casino

When it comes to regular, wager-free rewards on slots, no casino can beat PlayOJo! This casino not only offers up to 50 wager-free spins on first deposit, but also gives its players regular rewards through its Ojo Wheel and Ojo Plus Scheme. Players will get a spin on the Ojo Wheel either as a random treat or when they reach a specific level (when they've played a certain amount or number of rounds), and this will award them with free spins or cash rewards that will be free of wagering requirements. What's more, the Ojo Plus scheme will give players a small percentage of their stakes back in real cash, which means that the RTP on slots at PlayOjo will be slightly higher (by as much as 0.60%). In the long run, these regular rewards can truly make a huge difference, which is why we consider PlayOjo to be one of the best online casinos for slots!


50 no wagering free spins on first deposit. New customers only. Min. £10 deposit. 1 free spin for every £1 deposit up to 50 free spins. Spins valued at £0.10 each on Book of Dead only.
