The advertisement was dubbed "Roulette Rock Star", and saw a regular man going about his day, who then transforms into a rock star, presumably from playing the casino game at Sky Vegas.
The spot ended with a tagline that said, "This morning he was doing his recycling, but right now he's in Sky Vegas. And here, he's the roulette rock star riding an electric riff of red and black."
While meant to be harmless fun, the spot drew a complaint from the public, which caused the investigation that led to the ASA ruling that gambling seemed to make the man's life more glamorous by improving his self-image.
Sky Vegas disagreed with the ruling, but will have to pull the ad and not show it unless significant changes are made to the body of content.
