World of Card Games
Holger Sindbaek, a designer-turned-programmer from Copenhagen, Denmark, acquired an online multiplayer card game website, World of Card Games, about six months ago. Since taking over, he has increased its revenue to around $4,000 per month by retaining old users and enhancing SEO to attract new ones. The site features classic card games and offers a subscription option, although most revenue comes from ads.
