Spin, an addictive Windows Phone puzzle game inspired by Chinese philosophy

[Windows Central]

Spin 2014 is physics-based puzzle game inspired by the ancient Chinese philosophy of YIN and YANG, that describes how apparently opposite or contrary forces are actually complementary, interconnected, and interdependent in the natural world.
