If you sign up at an online casino, you’re going to get a casino bonus.

But there are some pretty bad casino offers out there – so why bother?

Because the best online casino bonuses in the UK are actually quite good. They’ll allow you to explore the casino in greater detail while playing a variety of slots and games. You might even have half a chance of winning (if you’re lucky).

Casino bonuses UK

Casino bonuses UK are bonuses given to new players in Great Britain when they sign up. All the top online casinos UK offer new players a bonus. But you’ll need to verify your account before using one, even if it’s free.

Verification mostly happens automatically; the casino uses the details you provide on sign-up to confirm your identity. However, sometimes you may need to send ID documents to them.

Once this is done, there are two types of casino bonuses UK that you can get:

  • Bonus money – this is a very common promotion that gives players bonus money to play with if they make a first deposit. Typically, the best first deposit bonus casinos UK give away the most amount of bonus money. This is normally a high percentage, e.g., 100%, 200%, and on occasion 300%. But always check the terms to see any small print.
  • Free spins – free spins allow players to play on slot machines at no cost. They are incredibly popular and are often given out after the first deposit. However, some sites give free spins on registration no deposit UK. This means you get to spin without committing any cash.

Best slot bonuses UK

What makes the best slot bonus UK?

The answer is one that gives you lots of credit so that you can play casino slots games without having to bet any of your own money.

As we’ve just seen, this can come in one of two forms: free spins or bonus money.

But what’s better – free spins or bonus money?

Ultimately, that depends on your preferences.

The upside of bonus money is that you often get a lot more credit to play with.

For example, some casinos give you 100% up to £100. This means whatever you deposit will also be given as bonus money too. But to get the maximum benefit, this requires you to commit more of your own money.

Free spins generally do not require you to commit anywhere near as much of your cash.

The minimum deposit to activate free spins is usually £20 or even £10. It’s also possible to get some when you sign up, as mentioned above. The downside is that free spins are typically restricted to a single slot or group of slots.

New casino bonuses UK

There are many new casino sites launching in the UK throughout the year.

The bad news? They often have poor casino bonuses.

That’s because they want to get as many people to join them without losing money. Therefore, they make the terms and conditions really hard to beat or tricky. Unfortunately, this still happens. In fact, the Gambling Commission issued a notice in February 2022 warning licensed operators about using “terms and conditions that are difficult to understand”.

Luckily, there’s a recent addition that offers the best new casino bonus UK by far. MrQ Casino is a fully no wagering casino. This means whatever you win from their bonus(es) is paid in cash. No tricky terms at all. They are also an instant withdrawal casino UK so any winnings can be paid out quickly. See our MrQ Casino review for more.
