Although Box Lacrosse is very complimentary to hockey, it is really more similar to basketball. The main similarities and differences are as follows:

• Like basketball, and unlike hockey to some degree, the game of Lacrosse involves a full team offense. Everyone plays offense, and everyone plays defense.
• The five offensive players are referred to as left crease, left corner, right crease, right corner & point ( centre ).
• In Lacrosse many "plays" originate from the corners where players on the possession team try to "set picks" on opposing players to hopefully free up a teammate for a possible scoring opportunity.
• Like basketball, there is a shot clock. A team who gains possession of the ball has 30 seconds to get a shot on net or they lose possession.
• If 2 players are going after a "loose" ball they must play the ball and not check the other player until he has possession. This again can be a little misleading especially when each player is battling and jostling for the ball. If a player makes a play on the body of the opponent before making a play on the ball, this is interference and possession is awarded to the opponent.
• When the ball goes out of bounds, the opponent of the team who last touched the ball gets possession.
• Players cannot pass the ball to the goalie in the crease at any time.
• An illegal cross-check is defined as: a) above the shoulders, b) below the waist, c) when the opponent is not on their feet, d) when a non-ball carrier is outside the dotted line on the floor. It is perfectly legal (and a very good strategy) to cross-check non-ball carriers inside the dotted line. o In higher levels (Pee Wee +), players who over-aggressively cross-check are readily exploited by strong offensive players, as they will be off balance with their weight forward, and prone to an easy roll or face dodge.
• When a goalkeeper is hit on the mask, play is stopped. The goalkeeper restarts play with possession of the ball in their crease.
• Under current rules, if the ball hits a goalie’s face-mask and goes in – it’s a goal.
• Slashing is not allowed at all in minor lacrosse. This is confusing for new parents and players because a well-executed stick check essentially uses a slashing motion. If the stick-check (“controlled slash”) makes contact with any part of the body (including gloves), that check will be considered a slash. Stick-checking (“controlled slashing”) the head of the lacrosse stick or portion of the lacrosse stick between the players gloves is legal.
• When a penalty is assessed, the non-offending team restarts play with possession of the ball near the centre of the floor.
• When one team offends (usually interference of non-ball carriers outside dotted circle), and no penalty is called, "possession" is awarded to the other team. The same applies for a player who looses the ball into the stands - the other team is awarded possession and the play is started once the whistle is blown by the referee.
• Checking from behind (back-checking) is to be dealt with severely as it is one of the leading potential injury factors. Back-checking is an automatic 4 minute penalty. If the player in possession of the ball turns abruptly to dodge or mitigate the contact while the defensive player is in the act of checking them, and this leads to a check on the back, this is not considered a back-check.
• Cross-checking in Box Lacrosse (hands apart on shaft, and shaft driven into the opponents shoulder or chest), is both legal and a very important and proper method of checking. This can occur on a player in possession of the ball anywhere on the floor, and can also be applied to players without the ball if they are attacking inside the dotted circle.
• High sticking is another area of confusion for parents. In some cases "Incidental" contact with the helmet by an opponent's stick is not automatically a penalty!! It is again a referee's judgment call.
• Players or goalies, out of their crease, will be penalized if they catch the ball in the hand. If they just contact it with the hand, it is a foul with possession awarded to the other team.
• Face-offs are taken with the open face of the stick facing your own net. The ball must come out of the 2' small face-off circle before other players can cross the restraining lines. An offense results in immediate possession to the other team. Watch for players sitting down on their knees with their butts on their heels – this is a common mistake.
• A player with the ball cannot push off with his free hand or arm! If he does (called warding off) possession is awarded to the other team. This rule is very misunderstood by new parents. Many times spectators will not notice freehand or arm pushing (by the way, as long as the player with the ball keeps both hands on his stick he can usually push, or shoulder or resist his checker ) and often miss the checking by offensive players especially action away from the ball.
• A loose ball or ball on the ground trapped in an opponent’s stick can be kicked in box lacrosse but not for a goal.
• When a team is shorthanded, they have 10 seconds in which to get the ball over centre and once over cannot go back, or a change of possession call is made with possession awarded to the opposing team.
• When a player is awarded possession by the referee, he must be given at least 3 metres of room by the defending player/s until the whistle signifies restarting of play.
• Once possession of the ball changes the team gaining possession has 30 seconds to get a shot on net or score a goal.
• Another big difference between hockey and Lacrosse involves the goalie's crease. If you go into the other team's crease to shoot or cut through it (i.e., when on offence), you will loose possession. If you go through the other team's crease (i.e., when on offence) and contact the goalie while he is in his crease it results in a minor or major penalty (“crease play”). If you are pushed into the crease you are okay but you must make every effort to get back out immediately. When on defence, it is perfectly legal, and often a good strategy to have a foot inside and to cut through your OWN goalie’s crease. This is perfectly legal, and in situations where players are defending against creaseman who are in low and tight, is often necessary. Defending players clearing the ball cannot take the ball from outside their crease and then enter it or pass the ball in to their goalie. (A defending player who has just gained possession can pass or roll the ball to their goalie if that goalie is outside the crease). Defending players that recover the ball while inside their goalie’s crease can carry the ball out of the crease.
• The goalie in Lacrosse can function just like any other player on the floor. This includes crosschecking while outside of the goalie crease. Also, a goalie can go anywhere on the floor.
• Charging. If an offensive player (usually a larger or stronger player) is carrying the ball at a full run, and makes no attempt to dodge or avoid the defensive player, and contacts them with shoulder / shoulder-helmet (head down) (or jumps into the air!) this will be assessed as charging, and a minor penalty assessed. If the referee determines there was intent to injure, then a major penalty may be assessed under this rule. Goalie’s cross-checking or running at offensive nonball players who have their heads turned back looking for a pass will generally receive a major penalty for charging.
• Players accumulating 5 penalties in a single game must sit out the remainder of play once they have completed serving their 5th penalty.

5. A minor penalty shall be assessed to a player who cuts through the opposition crease to check the ball carrier.

6. A player may cut through the opposition crease when not in possession of the ball unless it is giving him a distinct advantage in recovering a loose ball which will result in possession to the non-offending team.

7. In minor lacrosse, the ball may not be passed back into the crease. A goalie may not recover or receive a pass when outside the crease and then enter the crease.

8. If a goalkeeper has at least one foot in the crease, he may reach out to recover the ball or intercept a pass and return it to the crease.

The Face-Off (Rule 43)

Time Outs (Rule 70)

1. Each team shall be allowed one thirty second time out in the regular playing time of the game. Time out shall be granted only if requested by a player on the floor when his team has possession of the ball or during a stoppage in play. (Most experienced referees will recognize that Novice age players will be inaudible due to difficulties manipulating their mouth guards, and thus recognize timeouts called by coaches). If the team calling the time out was in possession when the time out was awarded, they re-start play with possession. In all other cases, play is started with a face-off.

2. If a team calls a time out to which they are not entitled, possession is immediately awarded to the non-offending team.
