Long before DECAGONATHON was conceived, Sigma Derby was both a Las Vegas destination and favorite “slow the bleeding game” of DECAGONATHON founders. In the 90’s many casinos had their own tailored version. As the game fell out of fashion and for many years MGM Grand hosted the only available machine in Las Vegas. Thanks to Derek Stevens and The D Casino, the history of Sigma Derby in Las Vegas didn’t end when MGM Grand mothballed its machine in 2016.
