Teams may play zone or man defense at any time during the game. Zone defense is recommended.
Once a team secures the rebound or inbounds the ball and is advancing in transition, defensive players may not play defense until they have retreated below the attack line. All defensive players must stay below the attack line until the ball crosses the attack line for the first time of that possession.
The attack line shall be designated by site director and game referees; example: volleyball line
Allowed in the 2nd Half. Defense must allow dribbler to cross the half-court line with both feet and the ball before applying pressure. A loose ball or pass in flight must cross the half-court line before the defense may apply pressure.
Allowed during the 5th period and overtime.
Penalty - Any illegal defense - one warning per half. Technical fouls for additional occurrences in each half.
NOTE: If the illegal defense is unintentional in the referee's judgment, the ball shall be awarded to the offense at the point of contact with no penalty.
The free throw line will be ten (10) feet from the face of the backboard. A shooter's foot may touch but not completely cross over the line. A maximum of 6 players, 4 defensive and 2 offensive, may occupy the free-throw lane. The space below block on either side shall be occupied.
Each player will shoot a free throw prior to the start of the game. Each successful free throw will be recorded in the score book and count in the team's overall score. One referee per team will simultaneously administer the free throws at each team's respective 1st half baskets.
Both teams will shoot an equal number of free throws. A team with fewer players than their opponents will be awarded additional free throws to balance the total team attempts. That team's coach shall select shooters who have missed their first attempt. If all players have made their free throws, the coach may select any player to shoot the extra free throws. Players who made free throws may not attempt a second shot until all teammates have made a free throw.
Only shots that hit the rim or backboard will require a pass to be made in the back court. The required pass must be started and completed in the back court before the ball can be advanced to the front court. On shots that do not hit the rim or backboard, no pass is required. This rule will not be enforced during the 5th period and overtime.
Penalty - Violation - ball awarded to defense at half court.
An offensive player may not be in the 15-foot key area for three (3) continuous seconds.
Penalty - Violation.
The offensive team has five (5) seconds after crossing half-court to cross the attack line and start their offense.
Penalty - 1st offense = warning, 2nd offense = violation.
