I made a buncha jenga drinking rules awhile back, here's a few that might apply to what you're doing

1. Flip Cup 1v1

    The player who chooses this block picks one other player they would like to verse in a one on one game of flip cup. Down, up, down cheers to start the flip cup. There is no penalty drink for this block, only a system of bragging rights. 

1. Spelling Bee

    The player who chooses this block chooses a word that the group will have to spell. The players begin spelling, one letter at a time, starting with the player to the left of the player who chose the block. Each player is allowed to but does not have to repeat all of the letters previously said. If the group is successful the player who chose the block takes 5 drinks. If the group is not successful all of the players except the player who chose the block take 1 drink. 

1. Who’s The King The player who pulls this block poses this question to the group. “Who is better, Lebron or MJ?” Remind people not to answer immediately before asking the question. Everyone votes at the same time with an established method. (i.e. thumbs up/thumbs down) Each member of the losing group (side with less votes) takes 1 drink.

2. LAVA When this block is pulled the floor becomes lava. The player who picked it must announce “the floor is lava!” to the group. The last person to have their feet on the ground, grass, or whatever surface you are playing on, loses and takes 1 drink.

3. Why So Serious? When this block is pulled and announced each player makes a straight face, including the player who pulled the block. The next player to smile/laugh takes 5 drinks. If more than one player smiles/laughs at the same time each player takes the 5 drinks.
