This document summarizes key findings from a survey of 385 US mobile gamers conducted by Inside Network in June 2012. It finds that most mobile gamers play casual games like words, puzzles and cards on their phones for short periods when bored or waiting. Younger gamers are more social, downloading more games and being less sensitive to price. "Free" is the top factor for both iOS and Android users when choosing a game. Friends and top app rankings influence discovery the most.
