Currently the AHL consists of 30 teams.

NHL roster size is 23 players, but only 20 players are allowed in any game. A normal game roster includes 12 forwards, 6 defensmen, and 2 goaltenders. The other 3 players are "scratches" and cannot participate in that game. Their purpose is to fill in if another player becomes ill or injured and is unable to play. These roster swaps are not allowed during the game though, only before the game starts. The only exception is if a teams starting and backup goaltender are both injured during a game and can't continue playing. In this case, the team is allowed to find any person they choose to serve as the emergency goaltender for the remainder of that game.

Not much.

Although recently, offside rules about crossing the red line in the neutral zone have changed. Offside is only called for violations over the blue lines on either side of the neutral zone.

Equipment has obviously changed as well. It was not mandatory to wear helmets in the NHL until the 1979-80 season for players entering the league. Veteran players could continue to go bareheaded. 1973 marked the last appearance of an goalie without a mask in an NHL game. Sticks were originally completely straight, making it harder to pass and shoot, but in about the 1960's the blades took on a curved shape. Pads were also made of entirely natural materials in the past, but now they're all made of lighter, more breathable synthetic materials.

The players are coming more from Europe than from before, most of them were from Canada. They're also much bigger, faster, and stronger.

The US Soccer Federation recommends that goals for U-11 matches be 6 feet high by 18 feet wide, but may vary in certain leagues and competitions.

In the NHL, the regular season ends in early April (this season all 30 teams play their final game on April 7th). The playoffs begin shortly after and 4 rounds of best of 7 play usually ends early to mid-June. (playoff schedule doesn't come out until later, but last season game 7 of the finals was June 15th, and regular season ended on April 10th).

Any 3 goals, or more, scored by the same player in one hockey game is called a hat trick.

Unofficially, 6 goals by the same player in one hockey game is called a double hat trick, but is a rarely accomplished feat in professional hockey.

Sometimes. In a case where the puck has been flipped into the air, a player can use their hand to either redirect it back to the ice or momentarily "Palm" the puck and move it back to the surface of the rink. Holding the puck for any longer than it takes to get it back to the ice can incur a Delay of Game Minor penalty. In the case of the Goalie, they can catch the puck in their glove or trap the puck under their gloves or pads: Both situations cause a time stoppage and a faceoff in the goalie's Defensive zone.

There are three (3) twenty (20) minute periods during regulation time.

One (1) five (5) minute overtime period during the regular season, and an unlimited number of twenty (20) minute periods in playoff overtime.

During the first half of the game, the visiting team chooses the basket they want when they take the court. At half time, they always switch which basket they attack. This is the same for the NBA, the WNBA, and college basketball.

Yes.

Each team is allowed one (1) thirty (30) second timeout per game.

a shoot out is a over time when a game is tied and they go into overtime and no one scores.they each deke try to score indavisualy with no one but the goalie.each team does it 3 times and if still tied keep giong in till one team messes up and didnt score........................

If a player is in the defensive end, gloving the puck to a teammate is allowed.

If a player makes hand contact with the puck in the neutral or offensive zones and a teammate touches it next, a hand pass will be called and play is blown dead.

Should a player close his hand on the puck, a two minute minor penalty for Delay Of Game will be assessed.

Doing so in the goal crease by a player, other than the goalie, results in a penalty shot for the non-offending team.

From end-to-end the lines are:

Goal Line

Blue Line

Center Red Line

Blue Line

Goal Line

The Goal Lines are used to determine if a goal is scored (puck most cross entirely over) and for making icing calls.

The Blue Lines are for determining on-side and off-side calls. (Google offside for a better description)

The Center Red Line is used to in conjunction with the Goal Line in Icing calls. It used to be a part of the offside-pass rule (two-line pass) as well, but the league ditched that rule to speed up the game and increase offense.

Extra time is normally only played in knock-out competitions, where one team must win to progress to the next round. In most competitions two full periods of 15 minutes are played, with the winner being the team with the highest score at the conclusion.

However, some cup competitions stipulate that, in the event of the scores being equal at the end of the normal 90 minutes of play, extra time will be played and the match will be won by the first team to score during extra time. This is called a Golden Goal.

A Zamboni is a machine that smooth's the ice on a skating rink. The blades shave a thin layer of ice and collects the shavings in a large bin. Jets of water then cleans the ice leaving a smooth surface in its wake.

If the teams are tied after 3 periods (regulation time), the game goes to a 5-minute sudden-death overtime period. If they are still tied, a shootout is held, with 3 shooters per team. Once a team has more goals in the shootout, they are awarded one goal for the final result.

The winning team gets 2 points, counted as a regular win. A team losing in overtime gets 1 point, counted in the Overtime Loss column. Some papers still list Overtime Losses and Shootout Losses separately, but they're both worth 1 point, and the NHL makes no such distinction.

A penalty in ice hockey consists of losing one player who has to sit in the penalty box for a specified period of time (usually either 2 minutes or 5 minutes) during which his team must play one man short. The penalty is killed if the team prevents its opponent from scoring during this period of time.

Skaters from the opposing team are NOT allowed in the goalie crease. Players from the same team as the goalie can be in there. They can not, however, freeze or lay on top of the puck. If they do so, it is a penalty.

This is a fun game that will need a lot of tools. Some of these include bilao and a greased bamboo pole.

No, you may not pass the puck to a player who is currently in an off-sides position (both skates over the determining edge of the attacking blue line while the puck is not in the attacking zone).

According to NHL Rule 3b: "The goal posts shall be of approved design and material, extending vertically four feet (4') above the surface of the ice and set six feet (6') apart measured from the inside of the posts. A cross bar of the same material as the goal posts shall extend from the top of one post to the top of the other."

Yes. It has happened when a pass is missed and goes all the way down the ice and into the open net.

I understand how it could happen but I couldn't find anything on it definitely having happened in an NHL game.
