So this is where the waters get a little muddy.
Unibet has a gaming license issued by the Maltese Gaming Authority and separate licenses also in United Kingdom, France and Italy, BUT the license omits some of their own websites such as the .de and .eu sites. This is because online poker has yet to be legalised in some regions.
The Unibet site states that players from the following countries may have difficulties in accessing the site:
Albania, Antigua and Barbuda, Argentina, Bahamas, Belgium, Bulgaria, Burma, Canada, Cape Verde Islands, China, Cook Islands, Croatia, Cuba, Cyprus, Germany, Ghana, Gibraltar, Greece, Guinea, Guinea-Bissau, Iceland, India, Indonesia, Israel, Ivory Coast, Japan, Laos, Liberia, Libya, Lithuania, Luxembourg, Macau, Macedonia, Malaysia, Mauritania, Mexico, Monaco, Morocco, Nauru, Netherlands, Netherlands Antilles, Nigeria, Niue, Norway, Poland, Portugal, Russia, Senegal, Serbia, Sierra Leone, South Africa, South Korea, Somalia, Sudan, Switzerland, Taiwan, Thailand, Turkmenistan, Uzbekistan, and Zimbabwe.
This suggests that players in those countries cannot register.
However, with regards to poker the Unibet site only mentions the following countries as being restricted:
Burma, Cuba, India, Libya, Macau, South Korea, Sudan, and Zimbabwe.
