Gambling online has never been this popular: betting, casino, poker, bingo, keno and all kinds of lotteries are available to customers. All of the above are being played more than ever, and especially in the UK gambling online is becoming one of the nations favourite past-times.

Playing online has become so simple and easy, that physical casinos are losing customers at a rapid pace. Huge changes have taken the online casino industry forward and there's more money moving online than ever before.


New online casinos are popping up as their popularity rises. This brings new and fresh sites to the business, and 2016 has continued the golden age of online gambling.


- The constant evolving of online services

- Games can be played whenever, no matter where you are

- Dreams of becoming a millionaire

- The casino bonuses

- The fantastic payout percentages (95-98%) = bigger wins

- Tax-free winnings

- Safe money transfers

- New innovations, evolving games

There is no single reason, as it's more of a case of a thorough evolving in all aspects of online casinos and patterns in the behavior of people. For example, before 2010 it was the golden age of conservative betting and online poker. Online poker in particular soared in popularity thanks to the UK pros who led the way.

Dreams and availability:

Nowadays people aren't prepared to spend so much time on gambling, which has led to the immense popularity of online casinos. People aren't patient and want their winnings immediately. In betting and poker you only start winning after a considerable amount of time, whereas at casinos you can become a millionaire with just one spin! You don't even need to wager much to accomplish this. All kinds of rags to riches stories inspire players to join online casino sites. As the games also function perfectly on mobile devices, you can play wherever or whenever you want, as long as you've got a good connection!

Casino bonuses:

Naturally, unlike with poker and sports betting, you can't win long term from online casinos. However, with all kinds of casino bonuses and free spins you can gain a momentary advantage over the casinos, but in the long term you will always be a percentage or two behind.

Biggest wins:

Game developers like Net Entertainment are nowadays creating even better games in terms of win sizes. In the jackpot games you can win millions with a wager of just £0.20 and the average payout percentage is 95%. In the best games like Bloodsuckers the payout percentage can be as high as 98%!

Quality of service and reliability:

In addition to the better chances of winning casino games and online casinos have also considerably enhanced their services. Customer service operates via live chat, phone and email, while the casino bonuses are better than ever. There are an average of 500-1000 games at each online casino to choose from. Money transfers are completely safe and you can make tax-free withdrawals within 24 hours.


New innovations are constantly appearing: new live casinos, better bonuses, 3D casinos, easier ways of confirming your account, making deposits using bills and many other new features have taken online casinos forward significantly. Perhaps the most interesting new innovation is the Cherry Card, which might well be a regular feature at online casinos in the future.


As new online casinos and fresh casino bonuses are appearing at such a rapid pace, it's well worth the time and effort to follow news concerning online casinos. For example, we compile the most interesting news, offers and new casinos on our site. We also explain new innovations in detail in addition to telling people about new casinos and bonuses.
