Game is divided into Solitaire Phase and Control Phase.
Solitaire Phase: You play solitaire to improve the bond with your horse and make them run better.
Control Phase: You use the touch pen to navigate the courses, reacting to certain parameters and course attributes.
Races continue by switching between phases back and forth. In the final stretch, you use items and power you collected along the way, plus a whip to send your horse over the finish line. Raise your own horse, turn it in to a QR code and share it with others.

Probably won't come to the West. Sounds like it could be pretty fun.
