Here is how the game is played: Combine two decks of cards.

Make a pyramid with 8 rows, 8 cards in the bottom row 1 in the top.

Deal out the remaining cards, to however many people are playing the game.

Turn over the card on the bottom row at the left.

If anyone has that card number or face they can throw it down on that card and say "fuck you ________" (another players name).
The player must now drink the number of cards thrown multiplied by the row number.

More than one card can be given to a single player, and drinks may be assigned to more than one player on a single card.

So basically if a player is assigned 5 cards on row 8, they must drink 40 drinks or at least try their hardest.
