ONLINE CASINO SITES 2021

Year after year, online casino sites are the place of choice for players. The accessibility and access to the vast number of games help boost its popularity. In 2017, the gambling commission reported 34% of players decided to play at an online casino instead of going to a land-based casino or bookies, which was an increase from 2016.

A contributing factor to online casino sites growing in popularity is that they can offer higher payback percentages or RTP (Return to player). Online casino sites usually offer 94.5% and above RTP percentages. At traditional land-based casinos, the RTP can be as low as 70%. In layman’s terms, this means you have a higher chance of winning. In theory and I really do mean in theory here, if the RTP is 95%, for every £1 you deposit you’re likely to receive £0.95p. Since all online casino sites are programmed using a random number generator, outcomes are entirely random and unpredictable.

NEW CASINO SITES

There are on average 10-15 new casino sites popping up a month and I can tell you around half of those online casinos will have closed after 18 months. Unlike other comparison sites that throw anyone up on-site, we delve into the background of the new casino sites. We know who’s behind the casino site and we know their company history too.

So if anyone has a bad reputation within the industry and tries to disguise this with a new casino site, they won’t appear here. We won’t put any untrustworthy sites on here. That means on average we add approximately 5 new casino sites a month but this varies from month to month. We look for new casino sites with a solid reputation, a fantastic site, and great customer service.

MOBILE CASINO SITES

Online casino sites have also improved their software and technology along the way making everyone’s mobile playing experience an enjoyable one.

As our mobile devices become more sophisticated, it means playing online is just as good mobile as it is on desktop. Desktop remains the number one device to play on but expect this to change by late 2018. Currently, 49% of players visit casino sites on their desktop and according to the gambling commission, this is a huge 10% increase on the previous year. So this time next year, we can safely say over 50% of all online players will play on a mobile casino site.

Convenience is probably the number one factor for the rise of players playing at online casino sites on their mobile phones. The ability to play anywhere at any time is just amazing. Here’s an interesting fact for you, the number of those playing in the morning during their commute is on the rise. This time of the day also seems to be lucky when winning progressive jackpots.

COMPARE CASINO SITES

There are hundreds of casino sites around and with over 10 casino sites popping up every month, the choice is endless. It has been revealed that the average player is a member of 4 online casino sites in the UK. At comparecasinosites.com we have recognised this since day one and therefore we deliver a broad range of casinos to suit all of your player needs.

In 2021, there are a few things that come as standard at an online casino site, such as high levels of security, integrity, and confidentiality. Then the things which may differ from casino to casino we go through rigorously before featuring them here.

We start off by finding out who’s behind the casino to ensure they have a solid reputation and company ethics. Then we go through the player journey of signing up and verifying our account. We also ask a few questions to the customer support team to see how quickly they respond and the manner in which they respond to us.

Once we’re a fully-fledged member of the online casino we go through the site taking note of its navigation, ease of use, features, and accessibility to useful areas. For instance, casino sites with a search bar are always a winner. We really do go through everything, from the game selection, welcome bonuses, ongoing offers, and languages available.

You may find you love a particular casino for its roulette games for instance, but prefer another for its vast selection of slots. This is common among savvy casino players and that’s why our online casino reviews are detailed with a summary section too, highlighting all the important bits.

We always show you a wide variety of online casino sites so you can choose your favourites. We vet all of the online casino sites we featured on here, so you can happily choose your casino site.

WHAT TO EXPECT FROM ONLINE CASINOS IN 2021

Online casino sites are ever-changing and it’s our job to keep you up to date. In 2021, we have more fantastic games and user-friendly casinos. There are also a multitude of regulations to stay on top of, set by the Gambling Commission.

The biggest factor for online casinos is the mobile movement, mobile devices are simply revolutionising the industry. We all love playing on our mobile devices and casino sites need to stay up to date. As mobile device technology improves so does our player experience. So in 2021, expect more casinos to be purely mobile optimised and those that aren’t to vanish into oblivion.

Another factor we’re faced with in 2021 is online casino bonuses. Once upon a time, we all played with huge generous bonuses offered by casino sites. This is becoming rarer because the Gambling Commission has made casino bonuses taxable payable by the casino. This means for players in the UK big bonuses will just diminish. We won’t be seeing many welcome bonuses around the 500% mark but more around the 200% mark.

On the back of this, in 2021 we are seeing an abundance of welcome package offers. It’s common to see a player’s first three deposits receive a bonus. The package is usually made up of three smaller deposit bonuses and packaged into one. This is a great method since you can experience a new casino in different sessions and can make a solid decision about your entire player experience.

HOW TO PLAY AT ONLINE CASINO SITES

In all instances, you will have to register at the casino site with your details such as name, address, date of birth, etc. Don’t forget to confirm your email address too.

If you’ve played at a land-based casino in the past then you’ll quickly realise the games are pretty much the same and played in the same way. If you’re a newbie to casinos as a whole and unsure of anything then you can contact 24/7 customer service. Overall, online casino sites are easy to play at, you just select the game you want, choose your stake or betting amount and you’re away.

You will need your banking details or Paypal details to hand to make a deposit. Once you’ve done this once you usually have the option to store your details to save you from re-entering your details every time you want to make a deposit.

When it comes to confirming your account and identity it’s highly likely you will have to prove ID and/or a household bill with your name and address on it. You will have to scan this into the casino sites.
