The most important criterion of an online casino is, of course, a LICENSE!!!
The presence of a license tells us that all gaming processes in the casino are regulated and controlled by third parties and in the case of violations by the casino in relation to the player may have adverse consequences for the first. In Russia, online casinos are prohibited, so all casinos are registered in other countries and are controlled by the laws of those countries where the license was issued.
to date these licenses are not so much but if you judge not so little here is how they look:
Curacao Kahnawake ( Canada) Maltese
Gibraltar Great Britain
These are just a few of the dozens of licenses ! you can view the casino license in either the casino header or usually it is at the very bottom, where the basic information is indicated. It should be open for review . ALL CASINOS REPRESENTED BY US HAVE A LICENSE THE FULL LIST IS HERE
