This ping pong party game is fun and simple for anyone to play. Requires a limited amount of assembly, and prints with no supports.
You can make up any number of rules to play, a personal favorite is to print multiple boards for the number of players, and try to bounce ping pong balls across the table and get 3 or 4 in a row (depending on how difficult you want), before anyone else.
Another possible way to play, is to print a single board, and play a pseudo-version of tic-tac-toe, trying to get 3 or 4 in a row of your color before another player.
