Quidditch pong is the somewhat perfect combination of beer pong and Quidditch, guaranteed to add some ~magic~ to your drunken nights.
The game has the usual cups on either side, like beer pong, but mixes it up a little with the addition of three rings, bats, a Snitch, and a "Snitch cup".
The full list of rules can be found here, but the most important thing is the fancy new addition of the ~Snitch cup~.
You also have to choose (or be chosen by the Sorting Hat ;) ) for a house before you start – and they all have different abilities!
