Take a look at the explanation of factors that we consider when calculating the Safety Index rating of 7BitCasino. The Safety Index is the main metric we use to describe the trustworthiness, fairness, and quality of all online casinos in our database. At Casino Guru, users have the opportunity to provide ratings and blackcoin.co reviews of online casinos in order to share their opinions, feedback, or experiences. Based on these, we then generate a complete user satisfaction score, which varies from Terrible to Excellent. In determining a casino's Safety Index, we follow complex methodology that takes into account the variables we have gathered and evaluated in our review. This includes the casino's T&Cs, player complaints, estimated revenues, blacklists, and various other factors.
