Gambling License, Regulation, and Safety ⚖️

Licencing and regulation of online casinos are subject to the country of hosting. Every government has special conditions which these casino operators must satisfy. Gaming control and licensing organisations impact how their operations are carried out. These regulations cover responsible and legal betting to guarantee the safety of players’ cash, the legality of bets, and general user safety.

We strongly advise you not to play at an online casino without a casino license. Depending on your location casino online or gambling online might be regulated or not regulated. Always follow the rules of your own country.

If gambling is illegal in your country, sometimes it might still be possible to play at an offshore casino. Though don’t use a VPN to change your location, the truth will be revealed one day or another. This might result in you being banned from the online casino and losing your winnings.

It’s technically allowed to play online casinos in most countries worldwide. But as stated before, only when they have a valid online casino license. This might be a local license or an offshore casino license. The most popular and trustworthy casino licenses are the following:

If online gambling services are offered in the right way it’s legal most of the time. Gambling sites mention their owned licenses on their websites. Can’t you find any license? Avoid this gambling site.

Risks with Online Casino ⚠️

Besides falling for an unlicensed and unregulated casino, many of the risks of online casinos stem from the individual. Given the accessibility of the games, responsible gambling is necessary when playing online.

It is advisable to take regular breaks and watch out if you spend more money than initially intended. If you think you are developing a problem with gambling, contact an organisation such as gamblers anonymous. You can also begin by setting limits on your casino account, which should be readily available with a site that has a responsible gambling policy.

What is  House Edge in an Online Casino?  🏠

The house edge is the flip-side of return to the player and refers to the guaranteed income on any game for the casino. For example, in European Roulette, the house collects money when the ball lands on zero. Since this will happen on average once every 37 times, we can say the house edge is 1/37 or 2.7%.
