• Maximum roster size = 17 including seekers, snitches and at least 3 of each gender.
• In order to play, a team must have a minimum of 6 players, ready to play at game time. If a team has only two males or two females, they must play the entirety of the game a person down. They CANNOT substitute a male for a female and play with 5 males and 2 females or vice versa.

The Game


In General, our rules are governed by Quidditch Canada. See our House Rules below for exceptions. 


I. All balls will be placed in the middle of the field, and the team to grab the balls gains immediate possession.
II. Teams will start each game with exactly 7 players on the field, including at least 3 males and 3 females. If a team has only two males or two females, they must play the entirety of the game a person down.
III. All active players will start each game on their endline, and can move once the referee blows their whistle.
IV. All non-active players must remain off the field of play.
V. The game begins when the referee blows their whistle.
The game consists of two 20 minute halves, depending upon if the teams are punctual and ready to play at their scheduled time.
The Snitches are released in the last five minutes of the second half.
If a Snitch is caught before the 20 minutes are up, the game is automatically ended. If no Snitch is caught after the 20 minute half, the whistle is blown and the game ended.


I. Each team is made up of at least six players and a maximum of eight players are in play at any time.
Three of those players must be Chasers, two must be Beaters, one must be a Keeper and one must be a Seeker.
Each team must have three players of each gender.
Because the Seeker may spend the majority of the game off the field, Seekers do not count toward the number of required gender-specific players.
Players are forbidden to hold possession of, touch, kick, grab, pass, throw, or in any way use the ball of another position.
Possession is defined by when a player has complete and sole control of the ball.
No player may physically interact with the Snitch Runner.


3 Chasers
• These players must move the Quaffle down the field by running and/or passing, with the aim of throwing or kicking it through the opposing team’s goal hoops to score.

2 Beaters
• These players must throw the Bludgers at opposing players in order to temporarily knock them out of play.

1 Keeper
• This player is responsible for defending his/her team’s hoops and preventing the other team from scoring the Quaffle through them.

1 Seeker
• This player’s job is to chase down the opposing team’s Snitch Runner and remove the Snitch from him/her.

Note: Once the Snitch is caught, the game ends and points are tallied up. The team that caught the Snitch gets an extra thirty points.


Pinnie Colour: Blue
Game Ball Used: Quaffle
Chasers per Team: 3

Using the Quaffle

I. Running – Chasers may run with the Quaffle for an unlimited amount of time.
II. Passing – Chasers may pass the Quaffle to any Chaser or Keeper on their team. The Quaffle may still be played if it hits the ground. It may be passed or bounced along the ground.
III. Shooting – A goal is scored when the whole of the Quaffle passes through one of the three goals. Chasers must throw, kick, or pass the Quaffle through the goal hoops to score. They can be as close or as far away as they like to make the shot. Chasers may score from either side of the hoop.
IV. After Scoring – After scoring, all Chasers of the scoring team must return to the midfield line before attacking again. Keepers of the opposing team must gain possession of the Quaffle in the Keeper Zone before counterattacking.
V. Broken Goal – If a hoop goal is broken, displaced, or in any way knocked down, play should continue if the attacking team is in possession of the Quaffle and in or behind the Keeper Zone. If they are not, or if the defending team gains possession of the Quaffle, then play should be stopped until the hoop is fixed. No one may score in a hoop that has been knocked down. Intentionally dislodging a hoop goal will result in a Caution.
VI. Stealing – Chasers may not attempt to steal the Quaffle from opposing players once it is in their possession.
VII. Kicking – Chasers are allowed to kick the Quaffle once. The Quaffle must then be picked up before any team member is allowed to kick it again.
VIII. Deflecting – Chasers may use the Quaffle to block incoming Bludgers. If they are successful and they are not hit anywhere on their body, then the deflection is complete and the Bludger has no effect, even if the Quaffle is dropping during the deflection.


Pinnie Colour: Orange
Game Ball Used: Bludger
Beaters per Team: 2

Using the Bludger

I. Possession – Beaters may hold a Bludger and run with it for an unlimited amount of time.
II. Beaters may be in possession of only one Bludger at a time.
I. Any team in possession of two Bludgers must allow the other team to recover the third Bludger.
IV. A Beater recovering the third Bludger will be immune to the Knockout Effect until said Beater has gained possession.
. Passing – Beaters may pass any Bludger to a friendly Beater
Throwing and Kicking – Beaters may throw or kick a Bludger at an opposing player of any type in an attempt to “knock them out."
• The Beater must gain possession of the Bludger before the same Beater can kick it again.
• A Beater may not kick a Bludger while in possession of a second Bludger.
• A player struck by a thrown or kicked Bludger has been “knocked out.”
• Beaters are allowed to kick Bludgers once. The beater must gain possession of the Bludger before the same Beater can kick it again.
VII. Catching – Beaters may catch a Bludger that is thrown at them by an opposing player. If a beater catches a thrown Bludger, the Knockout Effect does not occur and the player may continue play as normal.
• Note that a caught ball has no effect on the thrower.
VIII. Deflecting – A Beater may use the Bludger to block an incoming Bludger thrown by opposing players.

The Knockout Effect

I. Being Struck – If any player is struck with a Bludger on any part of her body (excluding the head) or any part of their broom, that player has been “knocked out.” It is necessary that the Bludger be thrown or kicked with enough force to ensure that the player struck is aware of the impact. The Bludger must leave the hand or foot of the attacking Beater before it hits the other player to take effect.
A Bludger is live after being thrown or kicked until that Bludger touches the ground.
Every opposing player struck by the Bludger before it touches the ground is subject to the Knockout Effect.
Friendly Fire – If a Beater hits a teammate with a Bludger, there is no effect. The Beater who initially released the Bludger cannot be struck his own Bludger.


I. After being struck by a Bludger, the player must do the following before allowed to participate in any part of the match:
• Give up possession of any ball by dropping it. While giving up possession, players must not pass, toss, roll, or kick the ball.
• Retreat back to his/her set of hoops.
• Touch any part of any hoop.
II. Knocked out players are out of play and may not interact with any players or balls in any way, and may not sub out of the game.
• Any play made during or after a player has been struck by a Bludger is not counted. If a player willfully ignores a Bludger hit, that player is subject to a penalty.
• If a Seeker is hit by a Bludger before or during a Snitch grab, the Snitch grab does not count.


Pinnie Colour: Green
Game Ball Used: Quaffle
Keepers per Team: 1

Outside the Keeper Zone

I. While outside the Keeper Zone, the Keeper is subject to all of the same rules as a Chaser, including but not limited to the Knockout Effect.
• The Keeper may leave the Keeper Zone and may move as far down the field as he/she likes.
• The Keeper is allowed to score with the Quaffle.

Inside the Keeper Zone

Any Keeper with any part of the body behind or touching the Keeper Zone line is considered to be in Keeper Zone. While inside the Keeper Zone, the Keeper is subject to all of the same rules as a Chaser with the following exceptions:
I. Kicking – The Keeper may kick the Quaffle any number of times while in his/her own Keeper Zone.
II. Possession – When the Keeper is in sole possession of the Quaffle while in the Keeper Zone, opposing players must not attempt to steal it from them. If the Keeper attempts to steal the Quaffle while in the Keeper Zone, the keeper must gain sole possession of the Quaffle before she is granted immunity.
IV. Knockout Effect Immunity – While in the Keeper Zone, the Keeper is immune to the Knockout Effect. Beaters may continue to throw Bludgers at the keeper for the purposes of distraction, but the Keeper is not subject to any effects if she/he is hit.
V. Delay of Game - Once a Keeper has sole possession of the Quaffle, the keeper must make an effort to advance the ball, and cannot hold on to it indefinitely in the Keeper Zone.
• Furthermore, a Chaser is not allowed to pass the Quaffle back to the Keeper in an attempt to delay the game. Anyone the referee determines guilty of delaying the game will be warned, or cautioned for repeated offenses.
VI. After a goal has been scored, the Quaffle must be in the possession of the defending goal’s keeper before play can be restarted.


I. Nobody from either team may step inside the crease at anytime besides the Keeper
II. Stepping on the line is equivalent to stepping in the crease
III. The quaffle may be released in the air if the Chaser jumps from outside of the crease and releases the ball before landing
IV. No shots may interfere with the Keeper (i.e. no contact on the Keeper while shooting)
V. Entering the crease with the Quaffle results in an automatic turnover, whether the perpetrator has the quaffle or not
I. Entering the crease will also be the same as being hit by a Bludger: you must run back to your set of hoops and touch them to get back into play
II. Defenders may enter the crease only when following the Knockout Effect Rule


Pinnie Colour: None
Game Ball Used: The Snitch
Seekers per Team: 1

I. The Seeker must follow the Snitch Runner on foot and attempt to gain possession of the Snitch by pulling it from the back of the Snitch Runner’s shorts.

III. Seekers are subject to the Knockout Effect.
IV. Seekers may not use or touch any other game ball besides the Snitch.
. The game ends as soon as the Snitch is caught. The team whose Seeker catches the Snitch is awarded thirty points.
VI. The Snitch is caught when the Seeker has successfully caught the Snitch from the Snitch Runner. It cannot be caught if the Snitch Runner is ruled to be down or if it is not securely tucked into the shorts of the Snitch Runner.
. If the Snitch is caught off the field, the victorious Seeker must return to the field as quickly as possible with the Snitch. The opposing Seeker is not allowed to hinder that Seeker’s return in any way. As soon as the head referee sees that the Snitch has been caught, he/she will announce the end of the match.


Pinnie Colour Used: Gold/Yellow

• The Snitch Runner must be dressed in all yellow or gold.


. The Snitch Runner is allowed to leave the field of play. They may not leave the boundaries of the practice fields, and will be reminded of the boundaries by the referee before each match.

Ruled as Down

I. A Snitch Runner is ruled as down when any part of the Snitch Runner’s body other than their feet unintentionally touches the ground.
II. When a Snitch Runner is down, the Snitch is uncatchable. The Seekers must allow the Snitch Runner to rise to their feet, and an additional three-second head start before the chase can commence again.
III. In order to be mounted on a broom, a player must have the broom straddled between their legs and must be held up by the hands or legs.
 If a player dismounts or “falls off” their broom while on the field of play, any plays made by that player while off the broom do not count. The player is considered out of play until he/she has remounted the broom and followed the same procedures as the Knockout Effect. It is the responsibility of the player to abide by this rule. The referee will caution any player who fails to officiate themselves in this manner.
