From the Game's Introduction:
The Ten Thousand Stances is an RPG. I am going to assume you know what an RPG is. The basis of the Ten Thousand Stances is unarmed combat, high-flying kung fu antics, and earth shattering styles.
The Ten Thousand Stances (from now on shortened to 10KS) is slightly different from most RPGs, in that it is played with a deck of cards. Removing 10 face cards results in a randomization between 1 and 10, and a 1/42 chance of Critical Success or Failure.
