The largest and most popular sport across the entire Flattened Sphere, Fantasy-Basketball is a full-contact death sport in which two or more teams of between 10 and 200 players vie for control over a large and heavy stone and attempt to hurl it into a large pit in the center of a field, court, stadium, or station. Teams must balance their offensive attempts to score points by "sinking the stone" with defensive efforts to prevent the opposing teams to do the same. Despite, and in part due to, the simple ruleset, games of Fantasy-Basketball can become deeply complex and confusing, with many games results not clear until days after the event is over. Attempts to clarify or expand the rulebook to avoid this have been met with militant resistance from the fanbase.
The standard Fantasy-Basketball team has several roles, with several other roles outside of the standard teamup.
