Co-founder Jason Kapalka discussed the development of Bejeweled Blitz and the ethics of social gaming at a GDC Europe panel.
The developer discovered that social games are a service, not a product, and learned that making the game fun for users rather than finding ways to get money was the priority.
Kapalka said that games are a "perversion" of what communication channels on Facebook were originally intended for, and instead of showing interesting topics or recommendations, they are being used for spam.
"Social games are kind of evil right now," Kapalka said, while adding that PopCap cannot claim it is "100% evil free".
PopCap has set itself a series of "golden rules" for social network development. Games must be fun to play - for itself and for others - and offer viral feeds that the development team would be happy to display on their own walls. It will also only look into revenue models once people start to enjoy its games.
Kapalka also announced that Bejeweled Blitz will be coming to new platforms.
