Which Casino is right for me?

Online casinos offer one of the most fun ways to relax and get entertained at the same time. But before signing up at any online casino, it is important to check certain important factors so that the gaming experience is pleasant.

Below, we briefly look at some important factors & explain the importance of why one should check these before hitting the sign up button on even the best Euro online casino.

Online Casino Licence

Before playing on any online casino please ensure that the casino has a valid licence from a gambling commission so that the game play is conducted in a fair & open manner.

The major and well respected licensing authorities such as the Malta Gaming Authority (MGA) or the Gibraltar Gambling Commission ensure fair play and conduct various compliance audits in its licensee casinos. UK online casinos are governed by the reputed UK Gambling Commission.

Online Casino Games and Software

The gaming software determines the quality of game play in terms of graphics, sound, exclusive elements. Even the range of casino games such as online slots, progressive jackpot games, table games, live dealer games will depend on the casino gaming software available.

Popular gaming software in top slot sites include NetEnt, Microgaming, Yggdrasil, Play N GO, WMS & Evolution Gaming. The more providers a casino offers, the better variety of games the players will have.

Casino Bonus’ Playthrough Requirements

As casino bonuses are very popular and almost all casinos offer various kind of bonuses, such as, Welcome Bonus, deposit bonus, free spins, reload bonus, we thought it is important to touch on the subject of casino bonuses and their limitations. However, if you’re not a fan of casino bonuses and only play with real money, you may safely ignore this section.

A bonus is free casino money that increase your casino bankroll. Bonuses are great because they can be used to play real money casino games. However, every bonus comes with certain terms and conditions, such as, the maximum bonus amount, the games you are allowed to play with that bonus, play through or wagering requirements, maximum amount you can cash out from the bonus’ winnings, and so on.

Out of these, the bonus’ wagering requirements is the most important condition you should take note of as it decides how difficult it will be for you to actually withdraw real cash winnings from the bonus.

Wagering requirement is the number of times you must wager the bonus amount before you can withdraw your winnings.

As an example, a casino might require a wagering of 40 times on their welcome bonus of €100. Which means, you need to keep playing with that bonus money until its value has been wagered 40 times on eligible games, to reach €4000 (€100 x 40).

In a nutshell, the lower the bonus’ wagering requirement, the better it is for the player.

So before claiming any bonus on even the best European casinos, please refer to the bonus’ T&C’s first and ensure that you are content with the offers’ restrictions.

Customer Support

It’s the duty of a casino to ensure quick & efficient help to the customer whenever he or she is stuck during game play.

Providing 24/7 support over email & live chat is the norm nowadays, and some casinos also offer phone support lines. Some casinos also offer customer support in local languages such as Swedish, Norwegian, Finnish, Danish, German, Spanish, etc.

Players should check that such basic but useful features are available in a casino. It’s a good idea to use the casino’s chat facility to see their response time and efficiency before signing up.

Mobile Casinos

Playing on the go is quite an advantage with most online casinos supporting mobile gaming for iPhone, iPads and Android Phones.

Players should check if an online casino is, firstly mobile friendly or has a mobile casino app, and secondly, if all the important site features and games are playable on the mobile device.

Online Casino Spinz – We’ve got your back

At Online Casino Spinz our goal is to be a source of trustworthy and accurate information on online casino gambling. To achieve this we always strive to present objective, fair, and up-to-date information in our casino listings, reviews, help guides, and casino offers.

What We Stand For

We understand that many people do not have the time or the patience to go through a pile of content, and put trust and faith in the casinos and bonuses we present in our website. For this reason, we consider only licensed casinos of good standing that have a proven track record.

Granted, it may not be possible to give a guarantee, especially in the case of new casino sites. But here again, we can gather some useful facts by looking at the casino’s parent company, its sister casinos (if any), checking various gambling forums, and by verifying the casino’s licensing information.

Similarly, we take utmost care in shortlisting casino bonuses and free spins offers. This involves carefully checking their terms and conditions to weed out the worthless ones.

Winning and losing is part of gambling but rest assured that Online Casino Spinz will never endorse any casino of questionable standing. If you feel otherwise do let us know and we will positively look into your concerns.

Please Play Responsibly

Balance and moderation can be a virtue in one’s life. This is especially applicable to betting and gambling, where playing within one’s limits can avoid undesirable consequences.

We request our readers to enjoy playing, but with a clear mind. Remember, when the fun stops, stop. If you feel that you are showing signs of a gambling addiction then please visit our responsible gambling section, or take help from the below resources.
