Lick the back of the card and stick it to your forehead. For as long as the card is stuck there, you are an all-powerful cosmic genie. If someone knocks the card off, they must finish their own drink.
Put an empty box on your head until another player draws a Box Head card, or until another rule cancels it.
As soon as this card is drawn, all players must immediately place their thumbs to their forehead with fingers spread, resembling antlers. The last player to do this must drink.
If you identify as a female, take a drink.
Never Have I Ever
All players raise three fingers. Starting with the player who drew the card, go around the circle confessing something that you have never done. Eg. "Never have I ever ... rode a bike." If a player HAS done something that's been said, they must lower one finger. When at least one player has all three fingers down, the round ends, and all players must drink as many times as fingers they have lowered.
The person who draws this card has to continue play from the floor, under the table (like a troll under a bridge), until the next Troll card is pulled.
Take off your clothes.
Pick someone to spell a word of your choice. If they are unable to spell the word correctly, they must drink.
Place an empty cup in the center of the circle. Any time this card (traditionally the King) is drawn, the drawer pours some of their own drink into the center cup. When the fourth card is drawn, that player must chug the contents of the center cup.
Take a drink, and hold your cup up high above your head until your turn comes again.
Choose a word. Starting to the left, all players go around the circle saying words that rhyme with the original. No word can be said twice. The first player to fail to say a word or who says a word that doesn't rhyme must take a drink.
Jack of all trades
When this card is drawn (traditionally the Jack), the players on either side of you must agree on a task/dare for you to complete.
Stand on one foot until your next turn, or take one drink.
Choose a player on either your left or right and draw a tattoo on their lower back.
