Minimum playing time rule: All players must play at least half of each
quarter.
All players must check in (kneel below) the scorer’s table in order to
sub. into the game.
Midway through each quarter, the clock will stop and the buzzer will sound
(at a dead ball or at the scorekeeper's discretion). The ref will call for
subs and all players on the bench must be at the scorers table (on a knee)
ready to enter the game.
Free substitutions may take place as long as the minimum playing time rule
is satisfied.
No player may enter the game until the referee signals him or her onto the
court from the scorer's table area - (not directly from the bench).
