You only have to drink the first time something happens in a scene, and only if it didn't happen in the previous scene (e.g. if a person appears in two consecutive scenes, you don't have to drink to them both times).
- Drink when someone appears naked,
- two drinks if they have sexual relations,
- three drinks if they have sexual relations that are forbidden by law,
- Drink when someone does something for the sake of honor,
- two drinks if someone dies as a result
- Drink when someone says someone's house words, or "a Lannister always pays his debts"
- two drinks if it's their own house
- Drink when a nobleperson mistreats (by our lights) or scoffs at someone below their station (verbally; disdainful glances don't count),
- Drink when a nobleperson demands their rights, or is put in their place
- Drink when anyone's clothing inadvertantly slips,
- Drink for the appearance of someone who claims to be a King or Queen, and shout out their style, e.g "Robert, King on the Iron Throne!" or "Robb, King in the North!",
- drain your cup if it's the first time their claim is put
- ...except do NOT drink of shout when they are merely claiming the title because they are the mother or father of a King/Queen.
- Drink for the appearance or revelation of one of Robert's bastards,
- Drink when Robb acts like a lord, when Jon Snow is called a bastard, when Sansa is ridiculous, when Arya wants to kill someone, when Brandon wishes he could do something he is physically unable to do, or when Rickion does something creepy that makes you wonder if he's secretly plotting to destroy Westros
- Drink when someone drinks onscreen,
- two drinks if they finish their drink
- Drink for the appearance of a direwolf,
- two drinks if it draws blood
- Drink when battle is joined (including brawls, duels, etc, basically any commencement of violence where someone is fighting back),
- Drink when a dragon breathes fire,
- two drinks if someone dies as a result
- Drink for the appearance of Tyrion, drink when Tyrion does something cool, and most of all,
- Drink, and cheer, for the appearance of Daenerys Stormborn of House Targaryen, the Unburnt, Queen of the Andals and the Rhoynar and the First Men, Khaleesi of Great Grass Sea, and Mother of Dragons!!!!!!
- ...drink again if her presence is formally announced with more than one style (e.g. "Daenerys Stormborn of House Targaryen, the Unburnt"; just "Khalessi" is only one style)
- ...and cheer again and drain your cup whenever she earns one of her monikers (e.g. "the Unburnt")
"A drink" is a sip, not an entire drink. Failure to obey the rules must be punished, by a drink.
Some of these were taken from others' Game of Thrones drinking games, but most are new.
