The first seed shall be determined randomly by an uncontrolled event. After every game there shall be a random change in the RNG process (new seed, random timer, delay, etc.) in order to ensure that the RNG does not start at the same value every time. It is permissible not to use a random seed. Nevertheless, a manufacturer shall ensure that multiple games will not synchronize.
