Look & Feel of 21Bit

21Bit looks very similar to many other crypto casinos. However, it is not as forthcoming with information as we would have hoped. There are no significant terms next to each bonus. Instead, you have to go through the terms to see what they are.

In terms of navigation, the site can be browsed with ease. The game library gives players the option to filter games by type and software game developer.

21Bit is licensed by the Curacao Gaming Control Board. Various countries are restricted at this casino, including the United Kingdom and Northern Ireland, Belgium, Estonia, France, Gibraltar, Greece, Italy, the Netherlands, Slovakia, Spain, Sweden, Switzerland, Turkey and the United States of America.

Please check beforehand if you can play at this online gambling site.
