"Puzzles, particularly number puzzles, are popular," said Val Sanford, vice president of marketing at Zango. "What's interesting is that we're seeing several different versions of the same game being developed and enthusiastically received by casual gamers."
Consumers head to Zango.com for access to casual games, videos, music and other content, and in exchange, the online media company serves them ads via a browser toolbar add-on. The findings suggest that advertisers who target Zango's puzzle games may see the best ROI for their casual gaming investments.
