Mr. Porter attributed the game’s success to its real-time feel. Players can watch animated playbacks of their teammates trying to guess their creation before taking their turn. The word choices are another big selling point; in addition to standard selections like “orange” and “dynamite,” the game is liberally infused with pop culture references, like members of the Wu-Tang Clan and Skrillex, a dubstep DJ. “We’re also benefiting from hitting at a time when a lot of people are moving from feature phones to smartphones,” he said. Mr. Porter thinks that just as Facebook has a social graph — the people its users want to be friends with — OMGPop can learn more about its “gamer graph,” or the people their users like to play games with. “It’s really about relationships,” he said  of the game. “How well do I know you and can guess what you drew. That is part of the fun.”
