This presentation is an analysis of a specific genre of social/casual game, bubble shooting games, with a special focus on GameDuell's Bubble franchise. Michael Kalkowski of GameDuell will deliver a broad view of the genre's many players, a bit of history, and success factors for that sub-genre, including a view on the competitors' games. GameDuell's Bubble Popp was launched on their site in late 2009 but over the last few years has grown and morphed with a steady stream of updates, changes, and expansions to other devices (mobile) and portals (Facebook). Now a truly cross-platform experience, Bubble Speed and Bubble Popp are examples of how GameDuell was able to take a game in a known genre and quickly adapt it to fit in today's expanding mobile market. This presentation will be a look at what GameDuell has learned in the past 3 years and offer key insights into the benefit of true cross-platform compatibility.
