Gaming Support has been granted GLI certification for its BaseSys Navigator jackpot controller.
The certification covers mystery and progressive configurations within the US states of California, Delaware and Rhode Island.
"Gaming Support is proud to have cleared this first, very important hurdle," said Don Baugh, chief executive officer of Gaming Support. "For the past several years, the American controller market has been far too restricted, with only one or two vendors supplying product.
"This absence of competition has been at the direct expense of casino operators, who have been forced to choose from an unacceptably narrow range of offerings. We look forward to providing American operators with a worthy alternative and are excited by the ongoing proliferation of this new, very exciting technology."
