Online Casinos Offering the Best Bonuses

Whether you're looking for a UK casino or one that's licensed in a less popular jurisdiction, all casino sites offer casino bonuses. Your first deposit is a big milestone because it brings you a welcome bonus. Whether you're a bonus hunter or not, you have to have a good understanding of the bonus mechanics, how they work, and what wagering requirements are acceptable and favourable. Not all casino bonuses are worth it though, but our casino bonus listings include all types of bonuses, such as no deposit casino bonuses, deposit bonuses and free spins, which are commonly known as Bonus Spins or Extra Spins in the United Kingdom.

With as little as £/€10 (min deposit for most bonus offers) you can start with extra free spins, up to £/€40 in bonus money, and extend your playtime. Again, the bonus amount is only one piece of the puzzle, so don't base your decision on which casino site to join, solely on this. Have at least one look at the wagering requirements, or even better, check out the full terms that apply to the bonus offer. The first deposit bonus that's provided by the online casino is displayed next to the casino name. Moreover, if there's a no deposit bonus offer that's available upon sign-up, it's also shown next to the deposit bonus that you get on your first deposit.

Don't expect to see a lot of wager-free bonus offers. Not only is the word "FREE" treated differently now, but the bonus terms have changed in a direction that's not in favour of new players. Lastly, pay attention to the flag that we display on the bonus offer. If it's there, and it shows the flag of your country of residence, that bonus should be available to you! Country restrictions apply to new players for the most part. Subsequent deposit bonuses are usually subject to different terms. Besides country restrictions, players from some regions cannot get any bonus funds whatsoever, not even the welcome bonus!

Best New Casino Sites - Start Fresh with Top Newcomers

New casinos are cropping up online every week, but, casinos are going out of business as well. Well-established casinos have grown over the years, adapting to and overcoming any challenges thrown at them. It's safe to say that "the hardest steel goes through the hottest fire", but not when it comes to casino sites. New online casinos pick the best the market has to offer, in regards to the game library, the casino offer, the gaming platform and any security systems that are considered industry-leading. Instead of patching things up, new casinos are capable of offering the best experience on the market, from a service and technological point of view.

Regardless of your taste in casino games, be it table games or online slots, or maybe a specific casino game provider like Net Entertainment, NextGen Gaming or Microgaming, these new casinos have it all. NetEnt is a staple without a doubt, but others like Pragmatic Play and ELK studios are also gaining momentum. New casinos are not the best place for high-rollers, and we're pretty sure you know the reason why. Then again, these online casinos have one huge advantage, starting fresh. They don't have to deal with a past lousy reputation, and they are in charge of the brand image. While we're discussing new casinos, it's important to note that they are the ones that usually offer sign-up offers aka no deposit bonuses and sign-up spins. The reason being, to attract new players as soon as possible.

There is no one best new online casino. New casinos lose this limited period tag to newcomers, that are launched after them. Nevertheless, new online casinos are a bonus hunter favourite! This is why one of the main difference between a new online casino and a well-established one is the quality of the bonus offers, whether it's a first deposit bonus or a sign-up offer that does not require a deposit.

Most Played Casino Games - "Slot Hall of Fame"

Online slots are by far the player favourite game type, and we can't argue against this choice! They require little to no previous experience, and they're based on a variety of topics, themes and boast a wide array of bonus features. Nevertheless, few of them stand out from the rest and have gotten the attention of both online casinos and online casino players as well. These titles are well-known, and regardless of how long you're part of the online gambling community, you have to know these slot machines. If this is not the case, we recommend taking them for a test spin, but not with real money. You don't have to commit with a real money bet right away.

Progressive jackpot slots are also quite popular, but for very different reasons. We believe that video slots without progressive jackpots are more entertaining, and at times, more generous in the short term. While progressive jackpot slots aim for that one bigger prize pool, video slots give you the gaming win "high" more often but in smaller doses. All of these are available at UK online casinos, whereas players from other regions might have to look for alternatives. Luckily, the best online casinos displayed above are international online casinos, available in Canada, New Zealand and South Africa, among many other regions.

The latest slot releases are not necessarily the best ones. Despite efforts to introduce new online slot features, players value something else more, higher than average return to player! Table game rules are intimidating to some, which is why slot machines are the safe and easy choice to make. However, unsurprisingly, most slot games, come with lower RTP than table games. Quick tip, video poker comes with the highest RTP if played with max bets!

What is the Best Live Casino Online?

A decade ago, it was mostly about the number of casino games available, but now, the players' taste is refined, and they know that quality is more important than quantity. With the advent of high-speed internet, casinos got the means necessary to provide something different, live dealer casino games. Finding a live casino online is easy, but only a few online casino sites offer comprehensive live dealer game offers. A few years back, it was a monopoly, since there weren't that many live casino game providers. Nowadays, there are more than a dozen live casino studios, some offer live dealer games exclusively such as Evolution Gaming and Authentic Gaming, whereas others like Playtech, Pragmatic Play and NetEnt are both virtual and live casino game providers. What you see is exactly what's going on in bricks-and-mortar casinos. Besides, not only can you play from your home, but almost any mobile casino offers them as well, meaning you can play on the go.

Since most online casinos offer these type of games, we have a dedicated section for the live casino game offer. Live dealer blackjack and live casino roulette are by far the most popular games. There's a wide array of games which you should explore for yourself! In most cases, you will be playing Evolution Gaming games. Then again, Netent casinos that offer live games are becoming more popular.

Granted, bonus offers for live dealer games are somewhat rare, at least the ones that are available on your first deposit. However, once you're done with the welcome bonus, new doors are opened, and you should get access to deals for live dealer games, which, although come with modest bonus amounts, will extend your playtime.

Casino Games on the Go - Best Instant-Play Mobile Casino

More than 60% of all online casino players prefer to play on mobile. The demand for convenient mobile gaming action revolutionised the online gambling industry, reshaping interfaces, and the design of the apps. To make things better, you do not have to download any apps to play on mobile. Then again, we respect native apps that are available in the Google Play Store or Apple's App Store. UK online casinos are ahead of the game since UK casinos got the green light from Google a few years ago. Players from other regions will have to settle with the mobile web apps which do an excellent job.

Online casinos with proprietary platforms offer few extra mobile-friendly features which make a lot of difference. Leading, trusted online casinos sites like Casumo and LeoVegas had gotten special recognition for their mobile gaming contributions with multiple awards. They perfectly integrate games from various studios and make them accessible to the global audience for real money play, thanks to their versatile platforms that are compatible with a wide array of payment methods, and in multiple languages. Just putting it on the screen is easy, making it look nice, be functional and convenient, that's the tricky part. A mobile casino must show the cashier and make it easily accessible, but then it also should fit most of the games on the screen. If you were to ask a mobile casino player that rarely plays on desktop, you'd hear rather different criteria than one that plays on desktop.

Online Casinos for Mobile Casino Players

Things have changed, and all online casinos are mobile-friendly, but some more than others. It's not like there's one general rule that will help you identify a mobile casino that shows no interest in desktop players. Thanks to responsive websites, and cutting edge interface designs, it's safe to say that we're long past the term mobile casino, and we can generalise them under one category, online casinos. And this is good! A few years back new players had to complete wagering requirements playing on desktop only, and then some on mobile, which doesn't make any sense at all. Not a single casino site will discriminate against mobile real money deposit, why would they when it comes to the choice of games? Then again, some online casino games are recommended for desktop play only. If you want to find out why check out an Evolution Gaming stream both on desktop and mobile. It might take a min deposit to enter the lobby, but it's worth it.

Fast Payouts and Easy Real Money Casino Deposits

It's the area that nobody likes to talk about, but we all need to know it. The only thing that hasn't changed in this department is the minimum deposit. Most casino sites mandate a min. deposit of £/€10, but the industry median is £/€20. When choosing a real money casino site, checking which deposit methods are accepted is imperative. Credit cards are still the universal option, but online casinos are pretty keen on more convenient and more secure deposit methods like Trustly, Entropay, Skrill and NETeller among others. A word of advice, e-wallets like Skrill and NETeller are not the ideal choice for new customers, because most UK casinos exclude them as qualifying deposit methods for new customer offers. It's a big flaw which cannot be overlooked. Then again, once you lose the new customer status, you can use e-wallets as much as you like. PayPal casinos are a special type of casino sites, always among the top-rated ones with top-notch security and a spotless record.

Before you get any expectations whatsoever, we should point out that only UKGC licensed online casinos can accept PayPal deposits. That is unless there's a national gambling body in your country of residence, chances are, you cannot use PayPal at online casinos. It is, without a doubt, the payment method with the fastest transactions. Withdrawing from an online casino site is faster than doing so at a land-based one! Fast payouts are probably the number one criterion of the majority of online casino players.

Online Gambling from a Legal Perspective

A lot has changed in recent years, and it doesn't seem like the changes are stopping anytime soon. The Australian online casino market suffered a lot, the gambling advertising rules in the United Kingdom changed, and US casino players got their first legal online casinos. Although many operators and casino players didn't agree with what happened, we salute the developments in regards to responsible gambling. GamCare and Gamble Aware, with the entire movement named BeGambleAware, is making a lot of noise! Finally, it's been addressed that gaming should be fun, and players must be responsible. However, it's also been addressed that operators must also do something about it. This is why deposit bonuses and wagering requirements have changed so much. Moreover, this is why even we are doing more in-depth casino reviews, touching on responsible gambling measures and mechanisms, paying more attention to new customer bonuses and considering other terms besides minimum deposit and the max bonus amount.

Although only UK online casinos were first caught up in this responsible gambling advent, casino sites from other regions soon caught on. Following a range of fines, even Curacao casinos started promoting Gamble Aware and had to employ responsible gambling mechanisms like deposit limits, wager limits, and so on. Going the extra mile, doing that KYC check for all new customers pays dividends in the long run.

Playing at legal, licensed, regulated casino sites is the one option you got that we can recommend. Security is non-negotiable, no matter how high-quality product the casino has, no matter how user-friendly its design is, and regardless of how attractive the welcome bonus is. If you've heard of anything even remotely related to Casino Capitals Award, or an event of that kind in your area, chances are, gambling is very much legal.

What is our Best Online Casino List based on?

All of the casino sites on our list are well-known and well-established on the online gaming market. But why them? What does it take to become a recommended casino site, and take a spot on our best online casinos list?

  • Convenient Depositing - not limited to credit cards and e-wallets (Skrill, NETeller, PayPal)
  • Favourable Withdrawal Policy - choice of payment methods, fast payouts reasonable limits
  • Access to Bonus Funds - realistic wagering requirements, fair terms, transparency
  • High-quality Game Collection - not limited to Net Entertainment, Microgaming, Playtech and NextGen Gaming only
  • UX and Interface - game type filters, compatibility with multiple devices, navigation
  • VIP Benefits & Loyalty Rewards - how easy it is to acquire them and how good they are
  • Security and Reputation - license by the UKGC or a spotless record

It's worth noting that most UK online casinos look the same, especially if they're white label casinos. This is why the likes of Casumo, LeoVegas and Betfair stand out from the rest. Not only they accept a wide range of international and local payment methods, but they meet all of the criteria above. For example, all of them are Netent casinos, but they are more than just that. They take risks, and they were among the first ones to reduce the qualifying minimum deposit, to raise the max bonus amount to never-before-seen levels, but to ease the access to loyalty rewards and speed up payouts. Let's also not forget that they are all active promoters of responsible gambling, supporters of GamCare and Gamble Aware, and they do employ industry-leading security systems.

Since all of them fall under the "UK Casino" category, all are transparent when it comes to the full terms, and showing the significant ones next to all bonus offers, including the first deposit bonus, all welcome bonus offers such as free spins, no deposit bonus money and reload bonuses as well! The good news is that more online casinos are jumping on their train and avoiding shady practices.
