What Is the Bonus Crab and How It Works

Brand new casinos in the UK have never been more inventive, and the bonus crab feature is proof of that in action. Inspired by the thrill of an arcade claw machine at the amusement park, this interactive bonus game gives players a chance to win free spins, cashback, deposit bonuses, or even exclusive rewards with a single grab.

As more platforms embrace gamified features to boost engagement, this feature has quickly become a fan favourite.

Here’s how it usually works:

Prizes & Bonus Types You Can Unlock

Unlike other promotions where you’re usually limited to specific rewards, bonus crab casinos offer a huge range of potential prizes. This means that you have the chance to get some incredible incentives to fund your gameplay.

While the exact bonus amount you’re offered will vary from casino to casino, here are some of the most popular types of extras you can expect to see.

Free Spins

One of the most popular deals. You may win a set number of free spins on selected slots — often on top-rated games like Starburst, Book of Dead, or Big Bass Bonanza.

With some casinos, you may even get free no deposit spins to boost your luck with an extra spin without paying a penny.

Deposit Bonuses

Grab matched bonus cash, typically ranging from 50% to 200% of your first deposit amount. These are frequently subject to a wagering requirement and other terms and conditions. Look out for our list of the lowest deposit casino sites if you’re playing with a smaller budget.

Cashback

Casinos want to keep you playing for longer, so they may offer cashback offers that you can use when you’ve run out of money. It involves refunding a percentage of your losses over a period of time, so you can reload and keep on playing.

VIP Rewards

Finally, you may get access to rewards that are otherwise only available to VIPs. This can involve prize bundles, exclusive odds, cash prizes, extra loyalty points or any of the other different bonuses we mentioned above.

Why UK Players Love Casinos with Bonus Crab

The unpredictability of this feature makes unlocking bonuses much more exciting and interactive when online gambling.

UK players, in particular, love using casinos that offer bonus crab promotions because it’s much more engaging than the passive offers most casinos offer. There’s also the possibility of collecting high-value bonuses or exclusive rewards that you may otherwise not have access to.

You also can’t ignore the nostalgic feel of using the crane game; it gives an extra shot of excitement to every activity.

New Online Casinos with Bonus Crab

Below is our bonus crab casino list of top platforms we would recommend.

GGbet

GGbet has recently expanded into the UK market with a fresh, modern interface and a strong emphasis on both sports and casino gaming. Its promotions section is filled with seasonal offers like free no deposit bonus options, tournaments, and prize drops.

Fortunica Casino

It is a newer online casino that focuses on slot games and rewarding player engagement. With a clean layout and regular promotional events, it’s the kind of platform that’s well-suited to surprise. They also allow a range of payment methods, which is important for a good gaming experience.

Betfred Casino

While Betfred is a long-established name in the UK betting world, its casino section has seen a major revamp, especially in its mobile offering and bonus features. The brand frequently uses mystery rewards and interactive campaigns, so don’t be surprised if you encounter a claw-machine-style promotion.

Bonus Crab Casinos vs Traditional Promotions – What’s Better?

When comparing a bonus crab casino with traditional offers, there are a few key factors you should consider when figuring out which is best for you:

Feature Bonus crab Traditional promos
Interactivity High — you play to win a bonus Low — automatically applied
Excitement High Low
Rewards Varies by grab Known in advance
Skill/chance factor Random Random or fixed
Engagement High Moderate
Availability Growing in availability Available at all casinos

A bonus crab online casino is perfect for players who value engagement and entertainment, while traditional promos are better for those who want clear-cut rewards. Many casinos offer both — so why not enjoy the best of both worlds?
