Most Popular Casinos

It is hard to say what makes a casino popular. Is it the design, the game variety, the bonus offers, the providers they work with or the payment methods they offer? Actually, it’s probably none of these, although there are players who check every casino for all these factors.

But at the end of the day, the casino you keep going back to ist he one where you feel the best. It is more of an emotional than a rational decision. We have compiled a list of the casinos our members like the best. Check out our Most Popular Casinos here.

Latest Casinos

We are constantly on the lookout for new casinos to present to you. The creativity of casino designers is astonishing. There are permanently new casinos popping up, and the variety is huge. There are casinos that use retro styles, some are based on specific themes, some target specific player groups, and some are only using cryptocurrencies.

Whenever we start cooperations with new partners, we add their casinos to our Latest Casinos page first. So, check them out if you feel like something new.

Casinos with PayPal

PayPal Casinos got loads of players because PayPal is such a popular and convenient payment method. Even though PayPal is not available in every legislation, it is universally acknowledged.

There are countries that don’t allow PayPal in the gambling industry, so make sure what the situation is where you live. Where PayPal is legal, you might even find Casinos with PayPal bonuses.

Casinos with Paysafecard

Paysafecards are pretty much just coupons that you buy for money. Their big advantage is that Paysafecards are anonymous, so if you don’t want to see an online casino on your bank statements, Paysafecards are an easy way around them.

They are also available in many different places and for different amounts, so you have plenty of opportunities to load up your account for just as much as you need. There are a lot of Paysafecard casinos, so make your pick.

Freespin Bonus Casinos

Free Spins are probably the most popular bonus form of all casino players, and since casinos don’t have to explain much or come up with an extensive program, they like them, too. That’s why most online casinos these days offer a welcome bonus package that, among other things, includes free spins.

These free spins are connected to a certain number of slots, which you can freely choose from. If you are looking for the casino with the most free spins, click through to the free spins casino page.

No Deposit Bonus Casinos

What is the only thing better than free spins? Free money! Yes, there are casinos that offer welcome bonuses with no strings attached. They will transfer money onto your account just for you registering.

There are just two things you need to pay attention to when looking for No Deposit Casinos. The bonus money is going to be a lot less than a regular welcome bonus – usually under $/£/€10 – and you can’t withdraw bonus money. Bonuses are to play with.

Cashback Bonus Casinos

Not every casino does this, but cashbacks have also become a popular bonus variant, and it’s easy to see why. Cashbacks in casinos are rewards for loyal players on a bad streak. The casino will check your balance on a regular basis, and if it turns out you have lost more than a certain amount, the casino jumps in and gives you some of these losses back. Just like that.

We have made a list of casinos with good cashback bonuses. But remember, you should never lose more money than you can afford. A cashback is not your justification to loose too much money.

Crypto Casinos

We live in the time of cryptocurrencies, and gambling was one of the first industries to catch up on this new trend. By now, there is a whole range of casinos that accept cryptocurrencies as your private payment method. There are even some that only operate with crypto.

So, if you happen to own Bitcoin, Ethereum, or similar virtual money, you will find your favorite casino on our Crypto Casinos page.

Landbased Casinos

At the end of the day, there is nothing like the real deal. We visited and researched the best casinos on the planet, just to give you a glimpse of what the casino world looks like. Check out some of the best and most beautiful casinos there are.

You might even find some inspiration for your next vacation trip on our landbased casinos pages.

Obviously, every tournament has its specific game selections and requirements that players must fulfill to take part. Each tournament participant gets a fixed number of trials with a predefined stake.

Bonus without Turnover Requirements

Usually, most bonus offers are tied to turnover requirements. However, there are certain bonuses that forgo those conditions. This in turn enables players to withdraw winnings from bonuses without having to fulfill any requirements.

High Roller Bonus

Many providers offer a so-called high roller bonus apart from the VIP Bonus. This bonus is reserved for players that frequently deposit large sums and play with particularly high stakes. This kind of bonus increases in relation to the made deposits.



Deposit and Withdrawal

To guarantee a perfect gaming and online casino experience, the processes of deposits and withdrawals must be technically accurate. For that matter, reputable and licensed providers count on popular and thoroughly tested payment methods.

Regarding payment, the processes must be secure, fast, and dependable for all players. Moreover, real money payout as well as payout ratio are highly relevant.
