This article was updated Thurs., May 21, with further detail on Microgaming's future involvement with Intertops' green casino.
Intertops Casino, the online operator, will be parting ways with Microgaming due to the software supplier's recent decision to prohibit its licensees from accepting new United States players.
"Microgaming has today announced its agreement with Intertops Casino is drawing to a close, due to Intertops Casino wishing to operate in the US market," Microgaming said in a press release Wednesday.
In September 2008, Microgaming announced that an unspecified number of its United States-facing licensees had agreed to discontinue registering new American players or had left the United States market entirely.
The Isle of Man company said then that uncertainty existed among those licensees about the commercial future of online gambling in the States.
Intertops currently operates two online casinos -- one branded "red," and the other, "green."
The red casino will accept American players and is licensed by the Kahnawake Gaming Commission. It runs on software from RealTime Gaming, a developer based in the Netherlands Antilles.
The green casino does not accept United States play and is licensed by Antigua and Barbuda's Directorate of Offshore Gaming.
Microgaming confirmed Thursday that it will not be supplying software and services to the green casino.
Intertops, one of the industry's oldest operators, was spun off from Intertops Sportwetten Gesellschaft m.b.H., a leading sports bookmaker licensed in Europe since 1982.
