概要

Basketball is played by two teams of five players on a rectangular court, each defending one basket and attacking the other. Players move the ball by dribbling or passing, aiming to score by sending the ball through the opponent's hoop. It is a fast team sport that blends skill, tactics and teamwork.

目的

Score more points than the opponent by putting the ball through their basket. At the same time, each team defends its own basket to stop the other team from scoring.

重要なルール

  • Five players per team are on court; you score by putting the ball through the opponent's basket.
  • To move with the ball you must dribble (bounce it); walking with the ball without dribbling is not allowed.
  • You cannot restart your dribble once you have stopped it (no double dribble).
  • Physical contact is limited: pushing, holding or hitting an opponent is a foul.
  • On offense, the team must attempt a shot within a time limit (shot clock, 24 seconds depending on the federation).
  • After a made basket, the conceding team restarts play from behind its own baseline.

The team with the most points when time expires wins the game. If the score is tied, overtime periods are played until one team comes out ahead.

How do I set up ScoreZen to keep score in basketball?

Set up basketball in points-scoring mode: tap +1, +2 and +3 for each basket, with 4 timed periods (quarters). The Casual preset simply shortens the period length for an informal game; there is no automatic target score. If you want the game to end on its own at a total (e.g. first to 21), create a "Custom sport" and turn on a target score.

Can I run a basketball tournament or league with ScoreZen?

Works with tournaments and leagues in ScoreZen: each game is tracked in periods with a running score, and results feed a standings table by wins.
