There is an obvious advantage to using any promotional deals casinos usually offer, especially ones that are as easy to get as bonus codes – you get free spins, limited-time free play, or even some money on your account to play with.
What makes any Gamblizard promotion worthy of your attention, though, is that our experienced team has already done all the digging for you. That means you won’t have to spend hours scrolling through dozens of sites to dig up the deals relevant to your preferences – you can just scroll through one list.
Another benefit is that all the bonus options on our page have been pre-screened to ensure they aren’t issued by fishy sites with dubious practices.
There are also quite a few unique deals you won’t get anywhere else, not even on casino websites themselves. That’s because our team takes the time to connect with trustworthy casino brands and negotiate special bonus code deals for the Gamblizard community.
With that in mind, it’s time to move on to some things you’ll need to consider when looking for online casino promo codes in 2025.
We’ve just briefly touched on one potential issue you can run into when choosing a promo code in the UK, but there are several crucial things you need to keep in mind. Here are some tips you’ll want to follow to get the most out of each promotion and avoid frustration.
The best thing is that online casino bonus codes are mostly no-deposit. They give you access to free spins without putting any money in your account, unlike the most common welcome bonuses, which usually have a minimum deposit requirement.
Bonuses that can be unlocked with casino promo codes can be difficult to redeem, though, as they often have inflated wagering requirements to the tune of 40 to 60x. These can be fairly difficult to meet unless you get really lucky.
Don’t expect a huge game variety with bonus codes for online casinos, as they usually unlock free spins for slots. However, you’ll sometimes see they apply to bingo, scratch cards, and lottery, and the occasional classic table games, such as blackjack.
Some providers, PokerStars Casino, for instance, will cut up their bonus offer into chunks – of the total 150 free spins you only get 50 within 30 minutes of signing up, and then the same number in 36 and 72 hours. Of course, there is a one-week time cap after which the offer expires, which you see in other casinos as well, but in some cases, the cutoff point can be as low as 48 hours.
Even if you play for hours and everything goes your way, allowing you to meet the steep wagering requirements, casinos tend to put a fairly low cap on the maximum cashout amount, so don’t expect massive winnings with these offers.
Now that you know where you can find new casino bonus codes and what to watch out for, it’s time to go over all the different types you’ll come across in the United Kingdom.
The best way to evaluate the suitability of a promotional offer is by reading the terms and conditions. In the T&Cs, you’ll find information on which games are eligible for use with the promo code, as well as the wagering requirements, expiration date, and winnings cap. We recommend that you always check out the terms and conditions before claiming any online casino promotion.

The options here are various. Some require nothing else but to sign up (so no initial deposits are needed on your end), while others (such as casino match bonus codes) have a minimal deposit requirement. Still others may provide cashback, and there’s everything in between. To give you a better idea of these nuances, let’s go over all the different promo codes for online casinos you can find in Great Britain.
An offer for first-time players who’ve just signed up, usually in the form of a lump sum of £5 and all the way up to £30 or free spins.
Available upon making an initial minimal deposit, as defined by casino sites, this offer gives you additional funds that match the size of your deposit up to a stated upper limit.
Here, you have the Holy Grail of promotions, where you can instantly redeem all the winnings you’ve made with the money the casino gives you.
Similar to previous bonuses, it’s either free spins for slots or a fixed sum. Only you don’t need to actually make a deposit to your account first. The wagering requirements can be steep, though.
This is essentially a reward for loyal players, offered through a VIP programme or as part of a special promotion, especially if you are a high roller. Sometimes it can be given as a birthday present or correlated with holidays.
This is the most common online casino bonus code where you get a certain number of free spins, typically 10, 20, or 25. The number can vary depending on the casino, but it usually comes with wagering and minimum deposit requirements.
A simple offer where you get a sort of “refund” on some of the money you’ve lost during the day or week, up to a specified number. It’s frequently given as in-game credits, but you can sometimes get free spins instead.
Bear in mind that casinos will sometimes offer codes for an upcoming holiday – Christmas, Easter, and Halloween being the main big ones – as well as special events like the player’s birthday. Likewise, cashback bonuses may be a reward for repeated deposits or high stakes.
We now come to the big question, “What can you use these bonuses for?” There are lots of games to try out in each casino, but promo codes can be used only with a select few, so let’s see what these are.
We have put together a table covering the types of games you can typically play with casino bonus codes and those rarely or never included in such offers, with example games for each category.
| Game Type | How Often Casinos Offer Bonuses for Such a Game | Popular Game |
|---|---|---|
| Slot Games | 🔥 Very Often | Starburst |
| Roulette | ⚠️ Sometimes | European Roulette |
| Blackjack | ⚠️ Sometimes | Classic Blackjack |
| Poker | ❌ Almost Never | Casino Hold’em |
| Baccarat | ❌ Almost Never | Punto Banco |
| Live Roulette | ⚠️ Rarely | Lightning Roulette |
| Live Blackjack | ⚠️ Rarely | Infinite Blackjack |
| Live Poker | ❌ Almost Never | Three Card Poker Live |
| Live Baccarat | ❌ Almost Never | Speed Baccarat |
| Jackpot Slots | ❌ Almost Never | Mega Moolah |
| Video Poker | ❌ Almost Never | Jacks or Better |
| Crash Games | ❌ Almost Never | Aviator |
| Lotteries | ⚠️ Sometimes | UK Lotto |
| Scratch Cards | ⚠️ Sometimes | Scratch Gold |
| Bingo | ⚠️ Sometimes | Mega Ball |
| Keno | ⚠️ Sometimes | Keno Universe |
Let’s now do a quick recap and share a few final thoughts.
You can look for the promo on the casino website that offers the code to see if there is an expiration date. But there’s an even easier option. You can just enter the code and see if it works.
You should see the reward land in your personal account area. Otherwise, you should be able to see your game account topped up with free spins when you open any slot eligible for the promo. Mind that you may need to wait up to 30 minutes after registering for the reward to show up.
If you waited at least half an hour after claiming your bonus and nothing happened, the best course of action is to contact the customer support team and explain your situation. Any online casino worth its salt should be able to straighten out the issue within minutes.
As long as the promo code has not been redeemed yet, you can typically send it to another player. But if you used it when signing up, you shouldn’t be able to transfer it from your account to another.
No. You are only allowed to have one account per person (the same ID, IP address, and bank account). Moreover, remember that using a VPN or similar tool as a workaround will be considered illegal.
