The Aztecs played a sport called called tlachtli which was something like a cross between volleyball, soccer, and basketball. But to some players, tlachtli could be much more dangerous than any of those sports are today.
Two stone rings were set about 20 feet above the court, one on each of the side walls. If a player could knock the ball through one of these rings, his team won the match immediately. The player scoring the goal was allowed to seize the possessions of any spectator he could catch!
Members of the losing team did not fare so well. In some matches, the captain of the losing team was beheaded.
