Playing at online casinos

If you are a newbie and haven't played casino online yet and you want to get a good start you have a whole new world to explore! Playing online is smooth, simple and you don't even have to dress up like when you are visiting a landbased casino. Instead you can lean back with your laptop or mobile and choose between hundreds of different slots and table games. If you're not ready to play with real money you can choose to play in demo mode and most uk casinos are actually offering demo games for British players. If this is something you want to do you don't even have to create an account. So you can try different casinos in demo mode before you decide where you want to put your money. There are also free offers for new players so if you decide to become a member of a certain casino you get some free spins to try it out before you decide to make a deposit. There are some differences between online casinos and landbased casinos. First of all there are much more games to choose between when you play online. A landbased casino has a limited surface that can't accommodate unlimited slotmachines while an online casino can offer unlimited amounts of games without any trouble. Also you never get any bonuses or free spins no deposit when you play on landbased casinos. When you play casino online you get loads of offers and sometimes you even get free bonuses which means that you don't even have to make a deposit in order to play and win real money. If you choose to play casino online you will be amazed by the flexibility and all the possibilities! Hopefully you will find our guide useful regardless if you're new to this world or if you already have collected some experience.

Licensed casinos in the UK

As you probably have noticed already there are so many different UK casinos online to choose from today. If you haven’t been gambling online before it might be hard to know which casino is trustworthy and which casino is shady. But we can assure you that every online casino you can see in our top list is carefully reviewed and controlled by us – a dedicated team of casino enthusiasts with years of experience. We would never let any bad casino onto our website.

However, there is a way to see for yourself if a casino is reliable or not and even though you’re clicking any of our casinos you should check this out too. The safe UK casinos like SuperLenny are license by something called the UK Gambling Commission. If a casino has this mark in their footer you can feel perfectly safe. The UK Gambling Commission looks at casinos and make sure that they follow certain strict rules and regulations. For example – they will only give they’re approval to UK casinos that offer tax free winnings and casinos that offer they’re players the possibility to set their own limits on how much they can afford to lose in one month.

It’s really important that a casino that has a license from the UK Gambling Commission continue to maintain a fair and secure gambling environment because if they don’t the Gambling Commission will withdraw their approval.

Don’t be surprised if your favorite online casino has two licenses. Most UK casinos has their base on the Island of Malta and therefore they have the MGA stamp as well that stands for Malta Gaming Authority. This also proves that the casino takes their reputation and safety serious. And like we mentioned earlier we always make sure that the casinos represented in our casino guide are licensed and approved.

Casino bonuses to get online

As the competition is getting harder between online casinos in UK there are certain ways for casinos to attract players. The most common way is to offer an attractive welcome offer including both free spins and casino bonuses. At the moment there are really high casino bonuses to get as the casinos have to offer something really good in order to get new players. So players today have the best opportunities to get loads of extra money in the shape of a casino bonus or a certain amount of free spins. In our casino guide we provide you with the best bonuses and offers that can be found online. Some of these offers are also exclusive and we have negotiated the deals ourselves. This means that these offers with higher bonuses and more free spins are exclusive for our visitors. With this in mind you need to click on our links in order to get the special bonuses. Otherwise you will just get the standard welcome offer and not the high bonuses that you are entitle to! If you visit a casino bonus expert you will find more exklusive offers for casinos online.

We always look for new casinos with high casino bonuses and from time to time you will see brand new casinos listed on our site. Before we list a casino we always negotiate an exclusive welcome offer for you. So if a casino isn't willing to provide our visitors with something extra we will not list them on our site. We also review all online casinos that we list so that you can be sure that we only forward you to trustworthy casinos with a valid licenses.

So how do you know if a bonus is good?

Can you really get a 500% deposit bonus with no wagering requirements? Many times, casino bonuses really are too good to be true when you check the fine print. For example, there might be a…

  • Max cap on earnings from free spins, sometimes as little as £50.
  • Need to wager the bonus amount 90-100 times.
  • And you may need to do so in a very short time frame, as little as 1 hour!
  • Wagering requirements on deposit AND bonus.

As you can see, it’s not always as good as it seems.

So what makes a bonus worthwhile? We can simply reverse the list above:

  • No maximum profit limit.
  • Less than 35x wagering requirement.
  • Up to 30 days to meet the requirements.
  • Wagering requirements on only the bonus.
  • Low or no deposit requirements.
  • Ability to opt out of the bonus.

Now more casinos are eliminating the wagering requirements on bonuses. This is something we here at have been waiting on for a long time!

Now that’s a good bonus!
