Best Casino Welcome Bonus – Making the Right Choice

The best casino sign up bonus has the attractive potential to dramatically change the gameplay at any online gambling site with such offers. Casinos create these promotions to attract new players. That’s why it’s quite easy to fall into the trappings for promotions and find out you’ve joined a rogue casino. As a player, you’re bound to come across these offers. If you’re just starting out, it’s easy to believe that the best online casino welcome bonus would be the biggest one.

We’re here to save you the trouble that might come from that. Our team carefully navigates the casino industry and is ready to introduce the best casino offers 2021 has in store for you. As a rule of thumb, those aren’t necessarily the biggest ones. In fact, they might be quite small but times more rewarding than bigger promotions. Without a doubt, the best casino sign-up bonus will be the one that doesn’t require a deposit and is wager-free. But since in the UK casino welcome bonus offers like that are nearly impossible to find, you’d have to compromise.

Things to Consider Before Claiming a Bonus

We go into details in our article when talking about the essential things about bonuses. What you should always have in mind is that you choose a fair bonus at a safe casino. We’ve reviewed and recommended a whole host of those. You can start your search there. What we mean is that the bonus, whether it’s playable cash or extra spins, shouldn’t come with impossible wagering. Avoiding rogue casinos is also a must!

Online Casino Welcome Bonus – The Best Spots to Claim

With hundreds of gambling sites available to UK players, it might be a bit daunting when you set out on your way to choosing the best welcome bonus casino. Reading online casino reviews is probably the way most people would go about that. We all want to join the best welcome bonus casino, but there isn’t a one-size-fits-all solution. Players are all different in their understanding of entertainment and their desires. What you perceive as a must for the best casino sites might not be the same for other gamblers. Especially when talking about a casino sign up offer.

Those come in so many shapes and forms, it might take you longer to make up your mind about one specific than actually finding the right casino. But if you’re rash and it’s the promotion that attracts you, you risk joining a rogue casino. You can start your search for an excellent welcome bonus casino from our recommendations. We’ve reviewed and carefully evaluated the recommended UK online casinos with top bonuses before presenting them to you.

Regulation & Licenses

As attractive as a welcome bonus might be, it’s not worth it if you’re claiming it from a rogue casino. We recommend only UKGC licensed and approved online gambling sites. This ensures that foreign operators offering casino games for real money gambling to UK players will adhere to local regulations.

Fair & Diverse Game Selection

If you don’t join a regulated casino, you risk wasting your bonus on rigged games. In addition, casinos with small games selections fail to provide quality entertainment. We make sure the casinos you can join have sufficient and provably fair games so that you feel spending your bonus on them is satisfying.

Support, Transparency & Safety

In almost a 100% of the times, welcome bonuses come with strings attached. If a casino isn’t transparent about it, avoid it. If you can’t receive instant support on the topic of bonuses or anything related to your experience, avoid it. If your data isn’t encrypted, avoid it. To avoid all that, check out our top recommendations.

Appropriate Payment Methods

Sufficient banking options is another sign of a casino trying to do right by its players. Not to mention some methods might be excluded from bonus offers. It’s important to join a casino that gives you a sufficient choice for how to make your deposits and withdrawals. And they need to be familiar and trustworthy ones.

Advantages & Disadvantages of a Casino Sign Up Bonus

Casino welcome bonuses open a whole new world of opportunities for you. You can explore and test out games at your chosen gambling site. In addition, you can get a taste of some of the most popular titles. In general, the best casino welcome bonus British players can claim is a great kickstart to the fun times at a casino. But, of course, if it isn’t a no-deposit wager-free offer, even the best online casino sign-up bonus has its drawbacks. We’ve made a short overview for you, if you’re still undecided whether you want to opt for available casino welcome bonuses.

Steps to Claim the Best Casino Sign Up Bonus

Now that you’ve chosen a site, it’s time to bank that online casino welcome bonus. There shouldn’t be any significant obstacles before you. We’ve made a short overview of the process. It might slightly differ between casinos. But if this is your first time claiming a bonus, you can get a pretty good idea from the steps below.

  • Sign-Up: It’s crucial to remember that you have to be a new player in order to claim casino sign-up bonuses. You can’t open multiple accounts, it needs to be an entirely new platform for you.
  • Indicate You Want the Bonus: Either during the registration process or afterwards, you might be prompted to state your desire to receive a bonus. Not all are added automatically upon your first deposit.
  • Deposit the Eligible Minimum: Every welcome offer, which isn’t deposit-free, has an eligible minimum requirement you’ll have to deposit. Of course, you can deposit more if you wish, but the minimum is mandatory if you want the bonus.
  • Start Playing: While making the deposit, you might have to enter a related bonus code. That would depend on the casino and the promotional terms. After the transaction has been made, expect your bonus balance to increase with the bonus amount.

Of course, the best casino welcome bonuses would be no-deposit or wager-free, but it’s nearly impossible to find such. The most common casino welcome bonus UK players can claim consists of playable cash or bonus spins, or in the best-case scenario – a combination of both. Note that if the welcome bonus doesn’t consist of cash available for play but free spins on registration, they probably won’t appear in your bonus balance but separately.

Casino Welcome Bonus UK – What are the Limitations?

When you think you’ve finally found an excellent gambling site, it’s time to consider the casino sign-up bonus you can claim and play with. Many people pass on the opportunity to claim offers because they are worried it might cost them too much. But that’s not necessarily true. What makes a promotion the best casino sign-up offer is a blend of factors. We made you a short walkthrough to introduce you to our process when evaluating the casino welcome bonuses of leading gambling sites.

Wagering Requirements to Consider

Wagering requirements are the bane of many gamblers. Everyone prefers a wager-free promotion, but since those are so rare, you have to compromise if you want to play with a boosted bankroll. Ideally, you’ll find bonuses with 30-35x rollover requirements. This is the average manageable requirement, and we’ve made sure to introduce to welcome bonuses with such requirements.

Time Limits to Beat

Unfortunately, bonuses in general, not just welcome offers, have an expiration date. You’ll have to exhaust them within a specific time period, with 24 hours for spins. Cash bonuses start at 7 days, which is the least favourable time-frame, going up to 60 and even 90 days. Sometimes you’ll have to exhaust the bonus and clear the wagering requirements in that period, otherwise, winnings will be voided.

Game Restrictions

Check out the games you can use your bonus on. That’s especially important for bonus and free spins. If they’re few, you’d want to use them on popular and rewarding slots like Book of the Dead slot, for example. Other popular slots that get welcome bonuses dedicated to them are titles like Gonzo’s Quest and Starburst. You wouldn’t want to be restricted to lame and unpopular games.

Are You Eligible?

To be eligible to receive casino sign-up bonuses, you have to be a new player. It doesn’t matter if you’re just beginning to gamble or you’re a seasoned player. You have to be new to the casino and of legal gambling age of 18 or more, according to British law. Multiple accounts at gambling sites is a violation of casino policies.

Potential Winnings Limits

Maximum winnings and cashout limits are part of every bonus that contains extra or free spins. Playable cash bonuses don’t have such limitations, but with spins, the average maximum size would be £100. Some offers have even lower limits, and given you’ll have to clear wagering requirements, it might seem a bit unfair.

Payment Method Restrictions

The question of casino sites’ payment methods is partially related to the question of eligibility. To prevent fraud and to follow particular gambling regulations, some casinos exclude players using payment options like Skrill and Neteller from promotions. You can find that information in the offer’s terms and conditions. If that’s the case, you’ll have to consider alternative banking methods.

Types of Casino Welcome Bonuses You Can Claim

Online casino sign-up bonuses come in various amounts. Some are more attractive than others, especially if they’re bigger or no-deposit. Depending on your style as a player, you’ll definitely find a proper offer to claim. You can start your search from our recommendations for top online casino sign-up bonuses or do your own research. In the meantime, if you’re not exactly sure what options you have, here’s a quick overview.

  • Deposit vs No-Deposit Bonuses: To claim a deposit bonus, you’ll have to deposit the minimum required deposit or more. Those are the most common type of bonuses in regard to how they can be claimed. On the opposite side, we have offers that don’t require deposits. In the UK, no deposit bonus casinos are extremely rare. You don’t have to do anything to receive them, just sign up for the gambling site. What’s even rarer is for these online casino welcome offers to be wager-free.
  • Playable Cash vs Free Spins: Casino sign-up bonuses usually contain playable cash or extra spins. The playable cash comes as a match-percentage of your deposit. That can range from 100% to a staggering 500%, depending on your casino. On the other hand, free spins on sign-up will be a fixed amount of spins. For example, that might be a 25 Free Spins no deposit UK bonus. Keep in mind that for the spins to be free, according to the UKGC guidelines, they have to be no-deposit and wager free. In all other cases, they’ll be extra or bonus spins.

Can I Make Real Money from Welcome Bonuses?

Yes, you can, if you’re lucky enough to win. Welcome bonuses might not be your real money, but they are used to generate real rewards. That’s why they come with particular wagering requirements. Only then would you be able to transform the winnings from the bonus into real cash and withdraw it as your own. That’s why so many people are on the hunt for the extremely rare no-deposit wager-free welcome offers.

Am I Restricted to How I Use a Welcome Bonus?

That would depend on the bonus. If it consists of extra or free spins, they will be dedicated to preselected slots. If they are in the form of playable cash, you’ll be able to use the money on the casino section of your gambling site. If you’ve claimed a live casino welcome bonus, it will be applicable only to particular games from the live dealers’ section at your casino. If you’ve claimed free bets or chips, they are also limited to particular games.

Why Can’t I Claim a Welcome Offer?

The only major exception to being able to claim welcome bonuses is when using particular payment methods. In order to follow regulations, as you can see from our guide, some casinos exclude them, and when you use them, you won’t be eligible to receive a specific promotion. Such payment methods are Skrill and Neteller. If that’s not your case, address your concerns to the customer support team to see if there aren’t specific casino policies preventing you from claiming the offer.

Do All Welcome Bonuses Have Wagering Requirements?

Unless the bonus is specifically wager-free, you will have to clear some wagering requirements. The best offer you can find would have a 30x or 35x requirement. Keep in mind that depending on the policy of your casino, you might have to wager not just the amount of the bonus but also the amount of your initial deposit. Some players find that daunting and bothersome. We’ve made sure to recommend you only fair promotions.

What Is the Best Welcome Offer I Can Claim?

We don’t get tired of repeating this. The best offer is the wager-free, no-deposit bonus. But those are like unicorns – awesome, yet rare. And yes, they do exist, but they are, in essence, casinos bleeding money for your benefit. Since gambling sites aren’t that charitable, the best promotion you can hope to find would be a fair one – rewarding, with moderate wagering, and offered by a secure casino.

Which Are the Best Welcome Bonus Casinos?

As you can see from our guide, those are gambling sites that have transparent bonus policies. They are also tightly secured, licensed by the prominent UK Gambling Commission. Other aspects of the best casinos to claim an offer from would be the available games. You don’t want to claim a bonus that you can’t use on a wide variety of games. After all, the idea is to get a good taste of the casino before you start betting your cash.
