How to Claim the Best Casino Bonuses

Thumbs Up Bonus is run by a group of experienced players who’ve collectively got decades of experience in the online casino industry. When we started playing, we wished that we’d had access to sites like ours that provide honest and unbiased opinions on the different sites that exist. Instead, we had to do things the hard way, which sometimes resulted in us feeling misled or confused by what initially seemed to be excellent offers.

Thankfully, you don’t have to go through the same experience, nor do you have to spend hours searching the internet and comparing pages and pages of promotions to narrow down the best online casino bonuses that are currently available to UK players. And, because offers change on a regular basis, you won’t find yourself being sent off to find an expired promotion or a completely different casino to the one you were expecting as we’ve constantly got our fingers on the pulse and keep our Best Online Casino Bonuses page updated accordingly.

Therefore, claiming the best casino bonuses is easy as 1-2-3. Step 1 involves looking through our current list of best first deposit bonus casino sites at your leisure. Step 2 involves clicking through to qualify for your favourite promotions using the quick “Visit” link, which will take you straight to the relevant sign-up page at your chosen online casino where you can get further information and read the bonus terms and conditions. The final step involves claiming your bonus and, most importantly, getting to use your free funds or free spins and hopefully scoop a win!

Are there Any Strings Attached to the Best Casino Online Bonuses?

Provided that you read the terms and conditions of every bonus promotion prior to claiming, anything that you perceive to be an issue will be identified, and you can always choose to walk away and look at another offer. The main risk is that bonuses don’t guarantee that you’ll win any money, but that’s the nature of online gambling – you can’t win all the time. In our experience, the most important factors to be aware of when reading Ts and Cs are: 1) is there a limit on how much you can win with your bonus? 2) What are the wagering requirements? 3) How long before your bonus and/or winnings expire? And 4) what kind of games can you play to meet the wagering requirements? Reputable online casinos will mention all of this information in their offer’s terms and conditions, so it’s well worth taking the time to read them.

Find your Perfect Playing Partner Today!

The best deposit bonus casino sites are just a click away, and new customers have the upper hand when it comes to choosing which deals to claim. So, if you’d like to fill up your new casino account with free spins and complimentary bonus funds, let us help you find the perfect site for your needs today!

Why Should You Care About Claiming the Best Online Casino Bonuses?

Whether you enjoy playing video poker, slots, live dealer games, scratch cards, casual games, or table games on your desktop, laptop, mobile phone or tablet, you’re not going to walk away with a big win 100% of the time. But, you can use online casinos to your advantage by making sure that you claim as many membership perks as possible. And, the easiest and often quickest way to do this is by helping yourself to the best casino bonuses on the market.

Bonus funds can allow you to play your favourite games and try out new titles for longer, and the more you play, the more money you could potentially win. The best online casino bonuses that you’ll find on this page can not only help to increase your bankroll but can also award you free spins to use on a sizzling-hot selection of top slot games.

But, as there are an ever-increasing number of online casinos and offers to choose from, it can sometimes be hard to see the wood for the trees. This is why Thumbs Up Bonus makes it our mission to provide you with essential information about the different types of bonuses that exist, how to claim them, and how to find the best online casino welcome bonuses for your needs as quickly and easily as possible.

What are the Differences between the Best Online Casino Bonuses?

There are several types of bonuses available, and each bonus can be referred to in multiple ways. So, it’s very important that you understand the differences between them if you’ve got your heart set on claiming the best online casino bonuses available.

Firstly, there are no-deposit and deposit offers, the first of which entitle you to free spins or free bonus funds without having to fund your account, and the second of which require you to make a deposit to qualify.

Sign-Up Bonuses

If you’re keen to locate the best online casino signup bonus, look out for the terms “sign up” or “no deposit” which are cost-free offers for players who wish to try out a particular casino without having to hand over any cash. As the best online casino signup bonuses can consist of free spins, bonus funds or both, we’ve created dedicated pages to walk you through the two different types of promotions. For more information, please visit our Free Spins No Deposit UK page and No Deposit Casino Bonuses page where you’ll find plenty of useful information on how to get your hands on the best online casino signup bonuses.

Welcome Bonuses

When it comes to locating the best online casino welcome bonuses, you’ll need to look for the phrases “welcome bonus” or “first deposit bonus”, as they’re usually one and the same. However, as well as sourcing some of the best first deposit bonus casino sites that reward you for making an initial deposit to your account, we’ve also rounded up the very best deposit bonus casino offers that reward you when you add funds to your account for the very first time as well as the second time, and sometimes, third as well!
