Not every party needs or should be interrupted by "structure." On the other hand, sometimes a little competition and cooperation, even if it's great fun, can help everyone involved to be more productive at work.
At Uptown Billiards, we've devised a hysterical "Triathalon" of pool, darts, and ping-pong where teams have to strategize how to best assign duos to different games played over four to six rounds - all culminating in an All-Star round at the end. The rules of all the games are simplified so that skill won't hold the event up (it can take a bad pool player an hour to hit all their solids or stripes in). We'll provide the scoresheets, assign teams randomly or politically (your choice), and even emcee the action. This activity is reserved for Whole Club parties, as it requires the use of both the Main and Parlor Rooms.
