Sweepstakes cafe is an
enterprise that offers opportunities to gain awards by buying an item or
service, typically access to the internet or telephone cards. They started to
occur sometime around 2005 in the Southern United States and gained popularity
rapidly. There is a dispute related to the activity of such enterprises and
whether or not they breach anti-gambling legislation. Operators and the
businesses are providing the systems used to retain that they function under
the legislation regulating bonuses and sweepstakes. But opponents of internet
sweepstakes cafe games have claimed that these installations are intended to
grasp the technical features of gambling laws.
