Casino security and reputation

The first thing you should do when you load a casino site is to check out which jurisdiction has granted it a license. Trustworthy European online casinos usually have a Maltese and sometimes Curacao licenses. To be able to operate in the UK, they must possess a license from the UK Gambling Commission. No reputable casino would hold a license from an offshore jurisdiction. If you decide to open an account at a casino licensed in Panama, for example, you should not expect anyone to protect your interests in case of a dispute.

Also, make sure the site has an SSL certificate (it should have a green locker next to the web address) proving that all sensitive information you enter is heavily encrypted and protected against ill-intended people.

Game selection

The largest online casinos that strive to meet all players’ demands never stay idle. They constantly add new games to their portfolio and sign contracts with new game providers. Still, there are a few renowned online casinos that use the services of one or two providers. 32Red, for example, is an industry pioneer known as a purely Microgaming casino and only the live dealer games are powered by Evolution Gaming.
So, if you see that the casino you have chosen lends its games from NetEnt, Playtech, Microgaming, Play’n’Go, NYX, Red Tiger, SG, Novomatic, you may rest assured that each available game is exceptional on its merits.

Games Mobile compatibility

Due to the rapid technology growth, players are no longer tied to the desktop computers. Every self-respected online casino has a well-optimised mobile site, but the largest among them go an extra mile and release native apps said to be more convenient for playing on the go.

Bonuses and promotions

Some players open a casino account because of the free spins or the free cash upon registration. Once they clear the wagering requirements or figure out that they are impossible to fulfil, they abandon or close their accounts. There are many examples of such failures to retain customers.
Prominent online casinos offer something beyond the welcome bonus. They have a gamification feature, reload bonuses, lower wagering requirements, or different missions for players to unlock and make their stay even more enjoyable. Opening an account at a reputable casino should be equal to erasing the boredom from your life.

Payment methods available

Online casinos are flexible in terms of deposits and withdrawals and most of them support VISA, MasterCard, Neteller, Skrill, Paypal, Euteller, Sofort, bank transfer among others. The caveat is to choose the payment method that has the best deposit and withdrawal limits. Beware that sometimes, fees on deposits and withdrawals apply. In most cases, it is not the casino, but your bank that deducts the fee.

Customer support

The best online casinos usually provide customer support round the clock. Players can get in touch with the customer care agents via live chat, email, and sometimes via phone. To eliminate the language barrier, the largest casinos’ employees speak not only English but also German, Swedish, Norwegian, Finnish, Polish, Russian, etc.

Blackjack is an iconic game, there is no two ways about it. It requires both skills and a piece of luck to beat the dealer. And remember, in order to win, your hand doesn’t need to be as close to 21 as possible. It just has to be better than the dealer’s. Think carefully and STAND when the risk of exceeding 21 is too high.

Largest slot casinos

The slots sections are usually the largest ones featuring 400 titles on average. Game providers compete against each other to release slots that outshine the product of their rivals, integrate an intricate feature to make it recognisable one. Although we have a soft spot for the NetEnt slots, we cannot deny that there are some really good products courtesy of Novomatic, Yggdrasil, Microgaming, BetSoft, IGT. Playtech also releases eye-catching slots on a regular basis, but we still grieve the removal of the Marvel-themed ones.
