How do we conduct our tests?

Our professional and objective team analyzes specific characteristics during each online casino test published on our site. In other words, nothing is “left to chance” and subjective opinions have no place. Instead, our main goal is to offer you reliable information of the best quality!

Game Catalogue

One of our first steps is to review the gaming catalogue offered by each Swiss online casino. Slot machines, table games, Live Casino or any other games won’t escape our review team. Moreover, we pay particular attention to the available publishers in order to determine the quality of the titles offered as well.

Available promotions and bonus offers

If you’re looking for an online casino that is generous with its bonuses and promotional offers, then Slots777 has the answers to your questions with its reviews of every legal Swiss online casino and the current offers available for each. Don’t waste time searching the web to compare sites individually!

Customer Service Quality

The quality of customer service is a very important feature for any online operator. No player can stand malfunctions or avoid having questions about games or services of an online casino. As a result, Slots777 reviews the reception, availability and accessibility of these “assistant” services.

Mobile Compatibility

Many players favor mobile devices when playing online. However, some operators have questionable compatibility of their services on smartphones and tablets, which is why Slots777 tests these qualities while remaining completely objective.

And that’s not all!

Slots777 also considers other essential features such as legal information, quality of slot machines, etc. in order to provide reasoned and comprehensive reviews. No Swiss online casino will be able to hide a secret from you!

Who Are We?

Keeping you updated in real time is our job!

Slots777 is a comparative site dedicated to Swiss online casinos deemed “legal.” In other words, our tests only review operators that are officially recognized by the CFMJ, the Swiss authority in charge of regulating and certifying online gambling activities.

Unlike other sites, Slots777 offers 100% reliable information verified by our team. In other words, our reviews contain information that is based on actual case studies, and not copy-and-pasted articles.

The team at Slots777 is composed of professional journalists having a common interest and passion for online casinos. No review is “without taste” or expertise about online gambling games.

Why have we created Slots777? Frankly, we are players ourselves. However, after having consulted the many other comparative sites for Swiss online casinos, we realized that these reviews seemed unsubstantiated and sometimes sponsored. And as fans, it became evident that a reliable and accessible site needed to be created. After several months of preparation, Slots777 made its web debut and won exceptional success that still remains pertinent today in Switzerland.

We try to remain connected to our readers and regularly update information on Slots777 to keep the popularity of our site afloat. That is why we remain at your service in order to stay on top of all of your requests!

Frequently Asked Questions

Are you a beginner, or simply have some questions about Slots777? This FAQ provides all the answers to the most common questions gathered by our team.

What is the best Swiss online casino?

It’s objectively impossible to determine the “best Swiss online casino.” The games offered and the quality of services from an operator never stop changing each year. Nevertheless, Slots777 keeps up by offering a ranking of the best operators every year, including 2020. Feel free to consult our reviews to assist you with making a choice.

Is the information on Slots777 trustworthy?

Absolutely! When editing our reviews, we make sure to verify all information that gets published. Likewise, we periodically analyze the online casinos listed on our site to make sure that our reviews stay current.

Why should you prefer “legal” online casinos?

You might be tempted by promotions offered by illegal online casinos. However, these operators don’t necessarily have a guarantee of fairness for available games nor of the trustworthiness of banking transactions (deposits and withdrawals). For your own security, Slots777 only reviews and recommends platforms recognized by the CFMJ.

Can I get additional information about an operator?

Slots777 offers complete and objective reviews. However, if you want to get additional information about an operator listed on our site, simply go to the “Contact” section of our site to reach us.
