Few sports seem so perfectly tailored for social games as horse racing: its rules are simple, its matches are short, and maintaining a good horse requires almost constant care.

Among the most notable is Rubber Duck's Hooves of Fire, which springs out of the gate while covering virtually every aspect of racing horses with only a few stumbles.
