Players

Hockey is played with six 6 players on the ice for each team; five 5 skaters, one 1 goaltender. The typical roster size of a hockey team is twenty 20 players; twelve 12 forwards, 6 defensemen, and two 2 goaltenders.
There are an unlimited amount of substitutions and they can happen at any time; during play and or a stoppage of play; except when the defensive team ices the puck.
The goaltenders have limited control over the puck, there is a trapezoid behind the goal where goalies are allowed to handle the puck, if they play the pluck outside this area below the goal line, and it will result in a delay of game penalty. This trapezoid does not exist in international play.
