What are Online Casinos?

Online casinos are the result of development by leading online casino companies, with the basic concept being a random number generator(RNG) that simulates the real life behavior of the relevant games, be it a slot machine, cards or roulette. The best online casino providers are well known and established companies such as
Microgaming, Playtech and Netent. These companies have been around for a decade and sometimes longer, most are publicly traded and constantly under the scrutiny of both accounting firms and local regulators. This means that customers can feel safe in the knowledge that the RNG engines behind these sites are honest and truly random.
The bottom line is that unlike in brick and mortar casinos, at the online casinos players can rest assured knowing that everything is constantly being monitored and external factors will not come into play with the results of games. Although this theoretically takes away the option of “gaming” the system, these “techniques” are either complete bullshit or illegal.

Opening an Online Casino Account

Opening an online casino account for UK users is a straightforward process. To register, you’ll need to provide basic information such as your full name, address, and phone number. Once registered, the next step is making a deposit by selecting a preferred payment method, with options like e-wallets or bank transfers being among the most popular and secure choices.

UK Online Casinos Regulations

The United Kingdom has some of the most progressive online gambling laws in the world and a government appointed regulatory agency called the UKGC is tasked with keeping the industry honest and adhering to a strict code of conduct which includes among other tight advertising regulations, anti money laundering checks and self exclusion options. Online casinos that break these rule are fined to the tune of millions of pounds and return offenders are at risk of losing their gambling license all together. The result of the hands on regulatory body is that the vast majority of online casinos in the UK do adhere to these standards and are very minded to the concerns of their consumers. At the end of the day, the main beneficiary is the citizen which has the opportunity to gamble in peace, knowing he is being looked out for.

Online Casino Games

The best online casinos have a wide variety of games including craps, baccarat, pai gow and many more but these popular games are the ones we pay most attention to when rating our online casinos:

• Roulette – A classic casino game and one which has translated very well to the online casinos as well, roulette can be played in the live casino or a virtual table and with several sets of rules (European or American as well as some wilder variations)
• Slots – Slots are the perfect example of a game that is tailored made for the computer screen, other then pulling a lever the experience is practically identical and players who enjoy slots will also love the online variety. In addition, since players from across the globe play the same jackpot games these regularly pay out massive amounts to players, even more so then live slot games.
• Black Jack – Another brick and mortar casino classic, blackjack is also a lot of fun as both a live casino game and a virtual one. Live dealer games are available at all major online casinos and provide a good substitute for the real thing when you don’t feel like dressing up and leaving the house.
• Other Products – Most good online casino brands also offer sports betting, bingo and poker and a casino with a strong complimentary suite of games can be a big advantage for when you might be interested in mixing it up

Online Casino Apps

The best online casinos will have good user experience products for both desktop and mobile devices and even specific applications for the more popular mobile phones on the market.

We have found that the amount of resources an online casino brand puts into creating an intuitive and seamless mobile experience is highly indicative of how much they value players enjoyment of their products, because the mobile experience is important within itself and seems to be a good indicator generally, we have taken the quality of the mobile casino apps into heavy consideration when ranking the top 10 online casino sites in the UK.

Top 15 Online Casino Welcome Offers

Welcome or signup casino bonuses can seem like a bit of a mine field to navigate at times, with the less reputable casinos often flashing enticing offers and what eventually turns out to be unattainable terms for actually enjoying the bonus funds. Even some of the more straightforward and known casino brands load up on difficult requirements which mean most new customers do not actually get to enjoy the full bonuses.

We have taken this into consideration and try and feature online casino sites and offers which are attainable, there are going to be terms to adhere to and these offers are not free money but an honest player who puts in a little effort should be able to attain reasonable results by applying to the bonuses featured in our table.

Online Casino Vs Brick & Mortar

The choice between an online casino and an old school b&m is one that comes down to personal preference, often dictated by the social situation but there are also objective differences that are with examining and make the online casino a much more viable option the vast majority of the time

• Online casinos are always available – a real life casino requires a commitment from the player while an online casino is available 24/7 be it sitting on the john or boarding a flight.
• Online casinos offer more variety – A live casino is limited by it’s floor space and there not be more then a handful of options even in heart of London. Online casinos however can offer endless amounts of games, there is never any wait and stakes can vary to a much higher degree.
• High rollers get better treatment – This is a common misconception when people consider the two casino options, although the past ten years have seen live casinos initiate reward programs in an attempt to combat the reward schemes of online casinos, online casinos still provide a much superior compensation package for new and regular visitors alike
• Welcome offers – Perhaps the biggest difference and the main reason why playing at an online casino is a much more viable proposition. As an online casino player you will be constantly courted and offered lucrative offers for when you choose to open a new account. The first set of deposits will usually garner healthy multipliers that can amount to thousands of pounds. On the other hand, at the live casino you can trade in whatever amount of cash into chips and that will be the funds you get to play with, an absolute zero added value compared to 100% and more at the online casino
