The Gambling Commission proposed to change the process that allows or disallows casino games from a white-list-based process to a black-list-based process. Rather than, as immediately after the introduction of the Gambling Act, restricting casino games to those specified (and described in detail) in the Rules of Casino Games in Great Britain, casinos could offer any games not explicitly prohibited by the Gambling Commission. This would amend the condition 9 of the Licence Conditions and Codes of Practice. These proposals were supported by the majority of respondents. In response to responses the Commission plans to produce a core games document as suggested and will place this on its website for reference. This will be a standing document and will not be revised annually as the Rules document formerly was. The revised licence condition will take effect from 1 June 2011.
