[i'm probably overthinking this but since beer pong is easier the more cups there are and harder when you have to aim for just one - roll a dice! with 10 cups on a side, the difficulty requires a roll of 8 or higher to get your ball in the cup. add 1 to the difficulty for every cup that is removed. you'd need a score of 17 i can't count or higher to get your ball into the final cup, for example! does that work or is that too complicated? i can also just make it "roll higher than x score to get whichever cup you were aiming for" if that'd be easier.]
BEER PONG
Yo, Satan! Beer pong work for you?
