If you are good at bouncing ping pong balls off of slimy wet tables into unstable stacks of used cups, then try out Stackems. It’ll bring out the best in you. And probably some of the worst bits too.


  • Table, circle, rectangle, anything you can fit a bunch of people around
  • 2 ping pong balls
  • Cups
  • Drinks

How to Play

Stackems is almost the exact same game as Slap Cup, except when you catch up to the person in front of you, instead of slapping their cup away, you add your cups to their stack. Like Slap Cup on hard mode.


  • Take a bunch of cups, and put them all around the middle of the table. Like 30-50 cups, depending on how many people you have/how much you want to die today.
  • Fill up all of the cups with about 1-2 sips of the parties drink of choice. Could be beer, wine, jungle juice, etc.
  • Get everyone gathered around the table, to admire all the cups you have assembled.
  • Give 1 ping pong ball to 2 different players, on opposite sides of the table.
Setup for a Game of Stackem

Getting Started

Once 1 person on either end of the table has a ball to start with, whenever someone yells “Go!” they can grab one of the cups from the center of the table, drink whatever is in there, and start bouncing their ping pong ball into the cup.


  • Once the first player successfully bounces the ball into the cup, they pass it to their left, who then also tries to bounce the ball into the same cup.
  • If you have the ping pong ball, you do not want the other ping pong ball to catch up to you, so try to bounce it in as fast as possible, and get it away from you.
  • If a player bounces the ball into the cup on their first try (not super unusual, I’ve seen monkeys play accordians,) they can pass the cup/ball combo to anyone they want, other than the other person trying to bounce the ball in.
  • This is a great opportunity to screw somebody! You can give it to the person directly before the person with the other ball to try and catch them, or give it to the person directly after the person with the other ball, to try and screw THEM! Or just pass it to someone who looks bored, we’re all just trying to have fun.
  • Note however that if you get the ball in your cup in one bounce, you cannot immediately stack the person with the other ball unless they are directly to the left of you. Newbies will try this shit every time.
  • Let’s say you have the ball, and the person to your left has the other ball. If you bounce the ball into your cup before they bounce their ball into their cup, you can stack your cup inside of theirs.
  • When this happens, the stacked cups get moved to the next person to the left, who immediately starts trying to bounce the ball into the stack of cups. The person who was stacked grabs a new cup from the middle, drinks its contents, and starts bouncing again.
  • While attempting to bounce the ball into your cup, you accidentally bounce it into one of the filled center cups! You can just take it out and keep trying right? WRONG!! Take that bitch, drink it, and add it to your own little personal stack of failure right there, you muppet.
  • This goes on for the whole game until all the cups are gone! Your stack will get pretty tall towards the end so you’ll really have to put some meshugana  on the ball.

Game Variations

  • Skyscraper: As the game goes on, the stack of cups will get pretty damn tall. At any point, the host or whoever is determined to be party leader can decide that it is officially Skyscraper Time. This is generally when one of the stacks is about 20 or more cups tall, and much harder to bounce the ball into it. Once Skyscraper Time has begun, if anyone bounces the ball into the giant stack in one try, they can immediately stack the person with the other ping pong ball.
  • Stank Cup: Not even really a variation so much as an awful surprise for those playing. While filling up all your cups at the beginning of the game, fill a couple with a little extra, maybe a shot of vodka, some wine, pickle juice, some of the gross liquid that forms on top of yogurt sometimes. Whatever you got. These cups usually get avoided until the end, making those final stacks all the sweeter.
