3 x 3 hoops, which is essentially the official form of half court hoops, is now an Olympic sport.

It's very cool and I wonder if becoming an Olympic sport will draw more of our marquee players to this exciting format
The game is played on a half court, a size 6 ball is used for all competitions and teams are made up of three or four players (three on the court, one substitute).
-There is a 10-minute clock, which is stopped for dead balls and free throws.
-The first team to 21 points, or the team ahead at the end of 10 minutes, is the winner.
-There is a 12 second shot clock
-A field goal inside the arc is worth one point, a field goal outside the arc is worth two points and a free throw is worth one point.
-After six team fouls, an additional free throw is awarded. At the 10th team foul and beyond, the opposing team is awarded two free throws and gets the ball back.
-If there is a tie, the first team to score two points in overtime wins the game.
-After a made field goal, the opposing team must dribble or pass the ball beyond the arc before attempting to score.
-For a missed field goal, if the offensive team gets the rebound it may continue to try to score without returning the ball to beyond the arc. If the defensive team gets the rebound or gets
a steal, it must get the ball beyond the arc before attempting to score.
-Substitutions can be done at anytime when the ball is dead, prior to the check-ball. One teammate must leave the court prior to his/her teammate entering the court.
-Like tennis, no on court coaching allowed
