  With the growing integration of smartphones into our daily lives, and their
increased ease of use, mobile games have become highly popular across all
demographics. People listen to music, play games or read the news while in
transit or bridging gap times. While mobile gaming is gaining popularity,
mobile expression of creativity is still in its early stages. We present here a
new type of mobile app -- fluidic games -- and illustrate our iterative
approach to their design. This new type of app seamlessly integrates
exploration of the design space into the actual user experience of playing the
game, and aims to enrich the user experience. To better illustrate the game
domain and our approach, we discuss one specific fluidic game, which is
available as a commercial product. We also briefly discuss open challenges such
as player support and how generative techniques can aid the exploration of the
game space further.
