Types of Online Casino Bonuses Explained
Casino bonuses and promotions are highly sought after and enhance your online gaming experience. These offers come in various forms, with some designed for new players and others aimed at rewarding loyal customers. Take a look at our list of the top casino deals below and who can take advantage of them:
New Player Casino Offers
Online casinos use new player offers to entice you to join their platform. Gambling sites make their new player promos as generous as possible to stand out against competitors, so it is worth shopping around to find the best ones.
💰Welcome Bonuses
One of the best casino bonuses you can pick up at regulated or non-Gamstop casinos is a welcome bonus. Casinos create these offers specifically for new players, so they’re often very competitive and the most generous ones you can find. You can find these promos in a variety of formats, from deposit matches to free spins, with some sites even throwing in an additional cashback offer.
- ✅Benefit – They boost your initial bankroll so you can play more of the games
- ❌Drawback – Bigger promos often have much higher wagering requirements
💰No Deposit Casino Bonuses
Once in a while, you might spot an offer for free spins with no deposit. Grab it when you do, as these promos give you free credits or spins to explore the games before making a deposit.
- ✅Benefit – Offer you free credits or spins risk-free
- ❌Drawback – Rarely offered by casinos
Casino Bonuses for Existing Customers
Online casinos in the UK also offer promos for their regular players. With over 38% of the UK public placing online bets in the past year, casinos understand the importance of rewarding their players. It is worth noting, though, that while the variety of these promos is more varied, they often aren’t as generous as welcome offers.
💰Free Spins
A top offer created for players at slot sites are free spins promos. These give you a set number of free spins on specific slot games. While they may not seem like much at first glance, they can be a great way to earn extra playing funds, especially on medium volatility games.
- ✅Benefit – Often pay out more than you may expect
- ❌Drawback – Casinos often apply low maximum payout limits to winnings
💰Deposit Matches or Reloads
Often, casinos will provide reloads or deposit matches to encourage you to add more playing funds to your account. Top deposit bonuses often double or triple your playing funds by matching your deposit at a rate of 200% or more.
- ✅Benefit – A great way to double your bankroll
- ❌Drawback – Usually have the highest rollover requirements
💰Cashback
If you want a casino bonus that pays back some of your losses, a cashback is the best promo to claim. In this case, the gambling site pays back a percentage of your losses (usually between 5% – 25%) when you play a specific selection of titles like Chicken Road game, slots, or similar over a week or weekend.
- ✅Benefit – Earn money back even when you lose your bets
- ❌Drawback – Usually don’t apply to all the games you may want to play
💰Rakeback
Fans of Texas Hold’em, Omaha, and other forms of regular poker can claim rakeback from the top UK poker sites. This bonus is similar to cashback, providing a percentage (usually between 10% and 40%) of the rake you pay to participate in eligible cash games or tournaments.
- ✅Benefit – Reduces the cost to play online poker
- ❌Drawback – This bonus typically benefits active players more than casual ones
💰Loyalty or VIP Programs
Another great way to get more for your money, pick up additional bonuses, and extra perks is by joining a VIP or loyalty club. These programs let you earn points based on your betting action, making them a great option for regular players. The more points you gather, the better the offers you unlock.
- ✅Benefit – Offer a great way to get more for your money
- ❌Drawback – To reach the top tiers you usually have to spend large sums at the casino
How to Spot the Top Casino Bonuses & Sign-Up Offers?
With so many online casinos promoting bonuses, it’s not always easy to spot which deals are genuinely worthwhile. To help you sort through them, we’ve outlined our top tips in line with how we rate UK casinos, making it easier to identify the offers that stand out.
- Check out the bonus terms – Every casino bonus comes with terms and conditions. In most cases, these are fair, but sometimes, they’re not, making it worth checking them out before you claim the offer.
- Consider the wagering requirements – Almost all offers have wagering requirements attached, but they are usually lower at the best payout online casinos. You must fulfill these requirements before making a withdrawal.
- Compare them to other offers – You will find that many casinos offer similar offers, but these sometimes vary in their requirements, making one offer better than the other. For example, a 100 free spins promo with a minimum deposit of £5 and 1x rollover requirements is a much better deal than the same promo with a £25 minimum deposit and 35x wagering requirements.
- See which games apply – Often only specific casino games count towards the bonus requirements. Top casino offers allow you to play a fun selection of games, making the terms easier and a lot more fun to meet.
- Take a look at what payment methods qualify – Top casinos give you a variety of ways to fund your account. These options should all qualify for the promos you want to claim.
Are Casino Bonuses Worth Claiming?
While all online casino bonuses look appealing at first glance, many come with hidden terms that make them much less appealing. Common red flags to look for include:
- 🚩Excessive rollover requirements on small offers
- 🚩24-Hour validity periods on large promos
- 🚩Promos with only one qualifying payment option
- 🚩Bonuses that don’t pay out winnings as real money
- 🚩Offers that don’t clearly outline their terms and conditions
💡Pro Tip: If the new casino bonus you want to claim ticks several of these boxes, you may want to look for another offer.
What are the Main Bonus Terms & Conditions?
Safety and fairness are two values you’ll find at top casino sites. Trustworthy platforms protect their players, but they also have to protect their businesses. One way casinos do this is by applying terms and conditions to their promos, to make sure they are fair and safe for everyone. Let’s look at the most common T&Cs you’ll come across:
Wagering Requirements
Pretty much every casino bonus has a wagering requirement, which tells you how many times you must play through the bonus before you can withdraw your winnings. Casinos apply these requirements to stop you from getting bonus funds and instantly cashing them out. If you try to withdraw before you have met these terms, you could end up forfeiting any winnings you have made.
Time Limits
If a bonus offer has wagering requirements, there is a good chance it will have an expiry period. Whether it is for slots or Crazy Time, it gives you an idea of how long you have to meet the promo’s T&Cs. If you don’t play through the promo before the offer expires, you’ll lose any winnings you’ve made using those promo funds.
Max Limits
Since an online casino is also a business, it can’t afford to pay out massive amounts of winnings players make from bonuses. For this reason, you’ll often find a limit to how much you can win from an online casino offer.
Qualifying Deposits and Payment Methods
Many promos come with qualifying deposit and payment method stipulations. What this means is that you must make a deposit over a certain value using a specific payment method to be eligible for the offer. Additionally, if you deposit less than the amount the casino outlines or use a payment method that doesn’t apply, you’ll lose out on the promo. For example, pay by phone bill casino deposits may not count as a valid deposit method for some bonuses.
Accessible Games
Not all casino games count toward the bonus requirements. You can check which games apply by reading the casino bonus T&Cs. Usually, slots count 100% toward these stipulations, while live games and table games like craps often don’t count at all. Choosing the right games will help you meet these requirements quicker and get your winnings faster. Use the table below to compare the terms and conditions of our top casino promotions.
How to Make the Most from a Casino Sign-Up Offer
You can get great value from casino offers in the UK, but if you know how, you can stretch these even further. We offer you our top tips for squeezing the most out of the different casino bonuses to get even more for your money.
🔥Tip 1 – When choosing a welcome offer, shop around and compare bonus T&Cs. Many casinos offer the same promo, but some have more manageable wagering or deposit requirements.
🔥Tip 2 – If you find a no-deposit casino bonus, always claim it. These offers are rare and a great way to make some winnings risk-free.
🔥Tip 3 – Check out the volatility and RTP of eligible slot games before claiming a free spins bonus. Games with low RTPs and high volatility are not likely to get you much in the way of winnings.
🔥Tip 4 – Always make sure that the wagering requirements on your reload deposit match are low. The higher these requirements, the longer you’ll have to play and the more you’ll need to spend before you can claim your winnings.
🔥Tip 5 – Use cashback offers when you’re learning a new game or testing out new strategies. They provide a great way to get back some of your losses while you learn.
🔥Tip 6 – If there is a loyalty program available, join it. If you play often enough, you can earn points that convert into extra casino offers or perks like quicker payouts or higher betting limits.
Responsible Gambling
Playing responsibly is the most valuable tip we can give you. There are many ways to stay safe while you play, especially at new casino sites. These sites have dedicated responsible gambling pages where you can find tools like betting and budget limits and self-exclusion programs. These casinos also offer access to specialised resources, such as:
- GambleAware – Provides support and counselling for those with a gambling addiction.
- GamStop – Offers a self-exclusion program that regulated casinos must adhere to.
- GamCare – Runs the national gambling helpline (0808 80 20 133) and a live chat where you can talk to counselors and get support.
Summary
As a UK casino visitor, you can find exciting casino bonus offers around every corner. These promos come in a wide range of styles, some featuring bonus funds and others offering exciting free spins. Knowing the good from the bad makes it easier to pick the best online casino bonus so you get the most value from the offer.
