An exception to this is when a player gets a penalty, and must serve the penalty in the penalty box for 2 minutes unless very severe. The team will be "down" a player on the ice, while the penalized player serves the time. The minimum amount of players on the ice will be 4 (3 skaters and the goalie). A goalie may be substituted for a skater, also known as "pulling" the goalie. You may "pull" your goalie at anytime during the game. Players are permitted to substitute at any time during a stoppage in play, during a goalie ring, or "on the fly". Forwards may cross over the Ringette line in there end, if there are only two defence. There can only be three people in one zone, with exception. The exception being when a team is two players down, then you can only have two players in the defensive zone (and of course your goalie), and you are allowed ALL three players in the offensive zone.
One note of interest is that the sticks are not 'cut off' hockey sticks. Ringette sticks have tapered ends, with plastic or metal tips specially designed with grooves to increase the lift and velocity of the wrist shot. A ringette stick is usually also reinforced because it must be able to withstand the bodyweight of a player without splintering - a ring carrier leans heavily on her stick to prevent opposing players from removing the ring. Hockey sticks are not designed to support such weight. Thus, using cut off hockey sticks would be a safety concern.
In hockey, the difficulty is in puck handling. In ringette, the challenge is in catching the ring. To catch a ring, a player must stab through the hole in the ring with her/his stick, usually while the player is on the move. Rules in ringette reflect this difference by forcing more passing, making ringette a game centered around passing. As a result, players learn to build up teammates, instead of depending on one or two dominant players. The lack of puck-handling in ringette also frees up players to focus on skating, leading to potentially a very quick tempo game.
AA would be considered one of the highest and most advanced level, while C would be considered the lowest. There is also the Recreational level. In the 2004/2005 season the NRL (National Ringette League) was introduced. The NRL is Open aged players at an AAA level. The league showcased 17 teams in three different divisions; Western Div (8 teams), Ontario Div (4 teams) and Quebec Div (5 teams).
