I.  On flag down, the fouling team must gain possession before play is blown dead.  The play can be called dead when the ball exits the playing field.  Loose ball does not blow the play dead.  

J.  The 1 Pass Rule is in effect for U9 division.  A player must be “hot” in order to shoot on goal.  A player is considered “hot” when a pass is attempted (does not have to be caught) in the offensive zone.  A pass must be completed if thrown from defensive zone to offensive zone, in order for player to be “hot”.  

The Field – Spectator Restrictions

a.  Spectators and media, including photographers, are not allowed behind the end lines except in stadium structures where permanent seats exist which are also protected by a fence or netting.

If the field is laid out in a manner that does not allow spectators and media to be located as prescribed by paragraphs a, b and c of this rule, as modified here, the game official can waive one or more of these requirements.

Game Administration – Sideline Managers

Each team should provide a designated Sideline Manager (one adult per team, on site, per game-day contest) to help encourage, maintain, and manage the sportsmanlike behavior of spectators and fans and assist the coaches and officials in keeping spectators and media an appropriate distance from the sideline. If used, it is the responsibility of each team administration to ensure that the Sideline Manager is present and in place to perform his/her duties; however, this is not a game day rule to be enforced by the officials.

Game Duration

Whenever possible, games will be scheduled in 1 hr blocks to allow for any delays that arise.

- Two (2) twenty (20) minute running halves.

- One (1) Timeout per a game, per a team. Timeouts may be used at any time during the game.

- Timeouts will be one (1) minute in length.

- The timeout will NOT stop the clock.

- There will be no timeouts allotted in the final 3 minutes of each half or overtime period.

- Halftime will be five (5) minutes.

- The last two (2) minutes of the game will be stop time unless there is a 3 or more goal lead.

- Penalties ARE stop time, but game clock runs.

Clarification on game clock and penalty time:

The game clock will never stop.  However, all penalties will be stop time! Table staff will keep game time and penalty time. The only timing that game officials will keep will be for timeouts. The scorer’s table game clock will be considered the official game clock.

The official score will be kept by both the table staff and one of the game officials. The table staff and the scoring official will confer after each goal and at all timeouts and period ending points to ensure score accuracy. After game is concluded the table staff and the scoring official will verbally agree on the final score before it is reported to tournament administration. The scoring official does not need to sign the score sheet.

Penalty minutes will carry over from one half to the next.

Team Rosters

Roster Size: A team must have a minimum of 7 players (1 goalie and 6 field players) present to begin a game. If, after the 15 minute grace period (outlined below in “forfeit” section), a team does not have the required minimum players the opposing team will be awarded a forfeit win. Roster maximum is 18.

Rosters are considered locked after the first game for each team begins.

Considering that this is a round robin tournament without a championship, players are permitted to play on multiple teams if age eligible.  Directors must notify the tournament director for approval.  

Team/Player Eligibility

For the High School divisions, all players on the roster must still be in high school. No players can have graduated before the event date (**see note about post-graduate players below).

For youth divisions (U9, U10, U11 U12,, U13, & U15) the age cutoffs are as follows:

HS: 2020, 2021, 2022, 2023

Youth:  8th/U15, 7th/U13, 6th/U12, 5th/U11, 4th/U10, 3rd/U9



Born on or after

Grade Equivalency

























Counts/Advancing the Ball

In the youth divisions (U9, U0, U11, U12, U13, U15) the only count enforced is the 4 second crease count for the goalie. There are no counts for advancement of the ball in the youth divisions.

For high school divisions only: Upon gaining possession of the ball inside the defensive half of the field, a team must advance the ball beyond the center line within 20 seconds. Failure to do so will result in a turnover, and the ball will be awarded to the opposing team at the spot of the violation or 20 yards laterally from the goal.

Final 2 Minutes of Regulation (U13)

No stalling.  Stalling is determined by referee.  Referee will give one warning to team if he determines they are stalling.  The warned team must advance the ball in an effort to score, or the referee will award the ball to the opposing team.


Braveheart!  Goalies can go over midfield, but each team must have at least one player on their defensive half.


Teams will be allowed a 15 minute grace period to arrive for a scheduled game.

If a team forfeits 2 (two) games in pool play and cannot present a valid reason to tournament administration for doing so, the team will be removed from the tournament.

If a team forfeits 1 (one) game in playoff/tournament play and cannot present a valid reason to tournament administration for doing so, the team will be removed from the tournament.

Note: All forfeit situations will be considered on a case by case basis by tournament administration.


Fighting will not be tolerated at the event. Any player, coach or spectator that is involved in a fight will be immediately ejected from the game and the remainder of the tournament. If the ejected person refuses to leave the field of play or continues to cause a disturbance that prohibits the game from proceeding, staff reserves the right to eject that person from the facility or contact local law enforcement.

In the case of a fight during a game, staff will defer to the game officials to determine which players were involved and should receive punishment. Staff will not take suggestions from anyone other than a tournament official (game official, scorer’s table staff, or tournament staff) as to what players were involved in a fight.

The game officials reserve the right to end a game if the game cannot be safely controlled.

Ejection from a game

If a player or coach or any other team representative (players & coaching staff) is ejected from a game for any reason other than fighting (player receives 5 penalties in one game, coaches or bench are given game misconduct) that person will be removed for the rest of the current game.

Also they will serve an additional suspension of the team’s next scheduled game including overtime that is attached to the said scheduled game.


Referee calls of any kind are not grounds for protest.  Tournament administration will stand behind calls made by game officials and will not change or override any call made on the field of play.

Note on roster checks: If a team suspects that another team is playing with an illegal roster of any kind, the head coach must alert game table staff. Table staff will contact tournament administration. See the definition of an illegal roster below.

Each team in the tournament is allowed to call for only one (1) roster check during an entire tournament and it must come from the head coach. If a roster check is called for Boom Town staff will check the rosters of BOTH teams involved in the game in question. The game clock will stop and remain stopped during a roster check and will not start again until staff gives the go-ahead to start the game again.

All roster checks must be called for during the game in question. Once the game is over, no roster check will be performed.

The following scenarios are deemed by Boom Town as teams using “illegal rosters”:

*Players not listed on the team’s official tournament roster

*Players participating on more than one team in the tournament

*New players appearing for games that are not listed on the official roster

*Players participating that are too old for the division

If during the course of a roster check, it is determined that a team is using an illegal roster, tournament administration will take appropriate disciplinary action. Disciplinary actions may rise to the level of team disqualification from the tournament if the facts of the case warrant such a penalty. The tournament administration reserves the right to administer punishment as it sees fit.


Note: It is allowable for a player to appear for a team after the tournament has begun as long as that player was listed on the original roster before the team’s first game began.

If a jersey switch of any kind becomes necessary during the tournament for any reason (inclement weather, jersey damage, etc) the team must get the approval of tournament administration

Note on Helmets

Hockey helmets (box helmets) are allowed to be used at Boom Town events.

Note on Penalties/Ejections for Goalies

Goalies will serve their own penalties at The Boomerang. If a goalie is ejected from a game, the game clock will be stopped if needed to allow a replacement goalie time to suit up in the proper equipment.

Note on Stick Checks

Each team is allowed to call for one (1) stick check per game. The call must be made to the game official and it must occur during a dead ball situation. The clock will stop during a stick check situation.


Coaches are only allowed one stick check per game!

30 seconds for illegal pocket (stop clock)

1 minute for illegal stick (stop clock)

If a stickis legal the challenging team will either lose a timeout or be charged a technical foul if the team does not have a timeout.

Note on Longpoles

Longpoles are U11 divisions and up.

Note on Body Checks

For youth divisions (U9 through U15): US Lacrosse checking rules will be in effect.

For Elite & Rising Stars Divisions: NFHS rules will be in effect.

Illegal Body-Check

An avoidable body check of an opponent after he has passed or shot the ball is an illegal body check. All stick checks, body checks, legal holds, and legal pushes must be on a player in possession of the ball or within 3 yards of a loose ball or ball in flight

The definitions below supplement, but do not supplant, all aspects, points of emphasis, and Play Rulings of NFHS Rule 5-3.


A take-out check is defined as:

a.        Any body check in which the player lowers his head or shoulder with the force and intent to put the other player on the ground.

b.        Any body checks considered more aggressive or more physical than necessary to stop the advancement of the player carrying the ball or to keep or move a player away from a loose ball. This includes but is not limited to: (i) any check in which a player makes contact with sufficient force and intent to knock down the opposing player; (ii) any check in which a player makes contact with sufficient force and intent to injure the opposing player; and (iii) any check made in a reckless or intimidating manner.

c.              Any body check on a player in a defenseless position. This includes but is not limited to: (i) body checking a player from his “blind side”; (ii) body checking a player who has his head down in an attempt to play a loose ball; and (iii) body checking a player whose head is turned away to receive a pass, even if that player turns toward the contact immediately before the body check. NOTE: Sports medicine research indicates that the severity of certain injuries may be reduced if a player can anticipate and prepare himself for an oncoming hit. Other sports medicine research indicates that peripheral vision may not be fully developed in many boys before approximately age fifteen. Game officials should be especially alert to blind side checks at all youth levels.  U15 and U13  Body Checking is permitted. To be legal a body check should be delivered in a generally upright position with both hands on the stick and the player initiating the check may not use his lowered head or shoulder to make the initial contact.  U11 and U9  No body checking of any kind is permitted.  Legal pushes   In all loose ball situations players


should “play the ball,” but incidental contact, “boxing out”, or screening techniques during such play shall not be considered a violation of this rule.  If a loose ball is not moving, stuck, or the players are having difficulty picking the ball up the referee may re-start play following the alternate possession rule.  Checks Involving the Neck/Head.  A player shall not initiate contact to an opponent’s head or neck with a slash, cross-check, or with any part of his body (head, elbow, shoulder, etc.), including any follow through to the head or neck.   Blocking of an opponent with the head or initiating contact with the head, including by an offensive player in possession of the ball (known as spearing).


U15 & U17

Slashing shall be called per NHFS rules.

U13, U11, and U9

Any one-handed check will be considered a slash, whether or not it makes contact with the opposing player.

Unsportsmanlike Conduct

Unsportsmanlike conduct by coaches and/or players will not be tolerated. Obscenities need not be used for language to draw a penalty. Tone, intent, and body language can all contribute to unsportsmanlike conduct. Players and coaches will exhibit the highest level of sportsmanship at all times. This means that in addition to the unsportsmanlike examples contained in NFHS Rule 5-10, any player or coach who uses derogatory or profane language on the field or bench, whether addressing a player, coach, or official may receive: first offense, 1 to 3-minute non-releasable unsportsmanlike conduct penalty; second offense, a 3-minute non-releasable expulsion foul.

Fouling Out

U17, U15 and U13

Any player who accumulates 4 personal fouls or 5 minutes in personal foul penalty time shall be disqualified from the game. A substitute for that player may enter the game when the disqualified player would have been permitted to re- enter had he not fouled out.

U11 and U9

Any player who accumulates 3 personal fouls or 5 minutes in personal foul penalty time shall be disqualified from the game. For U11, a substitute for that player may enter the game when the disqualified player would have been permitted to re-enter had he not fouled out. For U9, a disqualified player must leave the field but his team may replace him with a substitute; no man up situation should occur.

Note on Weather

Tournament staff will make any and all decisions concerning delaying or cancelling of games due to inclement weather. Officials, coaches, parent or any other non-tournament staff member should not attempt to stop a game because of inclement weather. Any concerns over weather should be addressed to tournament staff.

Tournament administration reserves the right to final say on all matters
