Simple Quidditch rules 

The game is run by a Referee or Announcer.
They will state that sign ups are open and what which teams are playing, for the time being pick-up quidditch will ignore houses and the two teams will be the Dragons and the Unicorns. Once the teams are complete (or the annoucer decides otherwise) the time of the game will be annouced. From the start time of the game players will have at least 24 hours (the annoucer will say what when this time limit ends.) to Owl the announcer how they player will play duing the game by selecting one of the moves listed below. Once all moved have been receved by the announcer (or the time has elapsed) the announce will report the outcome of the game. 

Chaser moves

• Defence (defends 1 goal)


• Offence (attempts 1 goal)


• Agressive offence (attempts 2 goals)

Keeper moves

• Defence (blocks 1/3 of goals)


• Aggressive defence (blocks 2/3 of goals)

Beater moves

• Defence (name two teammates to defend)


• Targetted Offence (name one opponent to attack)


• Opportunistic Offence (will automatically hit up to two 'Aggressive' players)

Example

Unicorns

• Chaser 1 offence


• Chaser 2 offence


• Chaser 3 offence


• Keeper defence

Dragons 

• Chaser 1 offence


• Chaser 2 defence


• Chaser 3 aggressive offence


• Keeper agressive defence

The unicorns attempt 3 goals, Chaser 2 defends one of them, leaving 2, the keeper then defends 2/3s of them 2*2/3 is 1.333 so the keeper blocks one goal.
The unicorns score one goal. 

The Dragons attempt 3 goals the unicorns keeper blocks 1/3 of them 3/3 is 1 so the keeper blocks one goal.
The dragons score two goals.

Now to include beaters

Unicorns 

• Beater 1 defend chaser 1 and chaser 2


• Beater 2 opportunistic offence

Dragons 

• Beater 1 attack chaser 1


• Beater 2 opportunistic offence

The Dragons first beater does nothing because chaser 1 is defended. 

The Dragons second beater does not see any openings.

The unicorns second beater oppotunitically hits both the the dragons third chaser, and the dragons keeper.

The unicorns make three attempts on goal, one blocked by the dragons second chaser, the others uncontested as the dragons keeper was put out by a bludgers.
Two goals to the unicorns. 

The dragons attempt one goal, and which the keeper fails to block (1/3 is 0.333).
One goal to the dragons. 

Notes on application

Chasers attempt to block or score a number of goals. Total goals equals the number of attempts minus the number of defends.

The keeper then blocks a percentage of goals, this is rounded to the nearest whole number. See below table for effect.
