Trustworthy and non-trustworthy casinos

The legitimacy of an online casino can be verified based on licensing, reviews, and customer care services. Apart from that, there are certain factors that determine the credibility of online casinos. 

Auditing and Legitimacy 

The online casinos need to have a badge of legitimacy before any player can actively invest in the casino for online gaming. Testing and auditing authorities conduct checking of the online casinos and give casinos the seal of approval, some of them are: 

  • eCORBA labs
  • GamCare
  • Gaming Laboratories International

These authorities investigate the gambling operators and sites to promote safe gambling, provide a better playing experience, support just gaming practices, ensure RNG (Random Number Generators) to impose fairness, and curb limits for deposits to prevent compulsive gambling. 

All online casinos require a license issued by the gaming committee in each country that legalizes gambling. The gambling license not only establishes the credibility of the casino among users and professionals but can also recruit gaming and service providers with ease. Licenses implement policies that must be strictly adhered to by the gaming operators while displaying their logos on the site. Unlicensed casinos do not have license logos on their site, which is the major difference of proof a user can get. Licensed online casinos are also legible for RNG Certification or the Random Number Generator Certification which are offered to casinos who have had their activities verified under surveillance. 

Each country has its own set of Gambling Acts and Gambling Laws that need to be catered to. These various Commissions license the casinos to operate worldwide. There are multiple legal boards in different regions that control the gambling operators and sites in that country. Some of them are: 

  • The United Kingdom Gambling Commission: The Gambling Act of 2005 set up the UKGC that governs the major of Great Britain and Northern Ireland. The UKGC controls all forms of online gambling and regulates the gambling organizations in the UK by providing them with licenses.
  • Gibraltar Regulatory Authority: The Gibraltar Regulatory Authority was formed after the passing of The Gambling Act in 2005. The Authority issues licenses and controls payments while inspecting for fraud or failure to abide by regulations.
  • Malta Gaming Authority: The Malta Gaming Authority governs the gaming laws in the country. Set up in 2001, this committee is focused on crime prevention and money fraud in gambling. 
  • Autorite Nationale des Jeux: Set up under the French Gambling Act in 2010, the gambling committee manages online gambling in France and inspects problems related to online casinos. 
  • Kahnawake Gaming Commission: Established in 1996 and enacted in 1999, the Kahnawake Gaming Commission controls the online casinos, online sports, and other online games and caters to Canada and the regions near the country.
  • Casino Regulatory Authority of Singapore: The board of authority set up in Singapore in 2008 deals with casino-related problems, governance of operators, and prevention of fraud.

Although not all online casinos need direct licensing from the commissions, a licensed casino is deemed safer due to its acceptance of self-exclusion schemes.

Experienced players and professional gamblers keep in mind the RTP of the game before delving into betting for wins. RTP stands for Return to Player or Percentage Return to Player which calculates the winning or losing percentage in a game.

The average RTP for most casinos is in the range of 92%-97% yet there are some casinos which has recorded high RTPs of 98% approximately.
