Draw cards, get drunk, repeat!
In King's Cup, your wits and luck will determine how much you'll have to drink. The rules are simple: players take turn flipping a card from the deck, and depending on the card's value they have to perform a certain action.
The twist comes with the Kings. At the beginning of the game, place an empty cup (the King's Cup) in the middle of the table, next to the deck (here, your phone). Every time a player draws a King, they have to make a rule that will have to be obeyed until the next King is drawn AND add something to drink in the cup. The unfortunate player that draws the 4th and last King will have to drink the content of the King's Cup, and the game's round will come to an end.
As mentioned earlier, each card value has its own "challenge":
Ace - Waterfall: Everybody starts drinking. The player who drew the card decides when to stop. Once they do, the player to their right can now stop drinking (or not) whenever they want. Rinse (literally) and repeat until every player has stopped.
2 - Two for You: The player who drew the card gets to decide who drinks.
3 - Three for Me: The player who drew the card drinks alone.
4 - Hit the Floor: The last person to touch the flood drinks.
5 - Five's for Guys: All the guys drink.
6 - Six's for Chicks: All the girls drink.
7 - Seven's Heaven: The last person to raise their hand drinks.
8 - Mate: The player who drew the card chooses someone to drink with.
9 - Rhyme Time: The player who drew the card says a word. The player to their right has to say another that rhymes. Repeat until someone fails and has to drink.
10 - Categories: The player who drew the card picks a category. The player to their right has to list an item that belongs to it. Repeat until someone fails and has to drink.
Jack - Social: Everybody drinks.
Queen - Questions: The player who drew the card picks another player and ask them a question. Repeat until someone fails to answer and has to drink.
King - King's Cup & Rules: The player who drew the card pours some drinks into the King's Cup, and picks a rule to be followed until the next King is drawn. If the rule isn't respected, the player at fault has to drink.
