A hand may be used to catch or touch an airborne puck. The puck must be dropped immediately within the radius of the catching player's stick. It is illegal to hold the stick horizontal to the floor at any time. Goalies when clearing the puck may not throw it above waist height, or throw it past the center line. However, goalies may shoot it with their stick.
Substitutions are free and can be made at any time.
When the puck is alive a player can only enter the court when the other player is completely off the court. A goal is scored when the puck passes completely across the plane of the goal-line. Goals may be scored from anywhere. Goals will not count if a stick blade is above the waist level, kicked in, the puck is batted by the hand, or an offensive player is in the crease. No goal can be scored while an offensive player's feet are in the crease.
