POG The Game is based on the early 90's craze that had its origins at the Haleakala Dairy in Maui, Hawaii. Back then the 'milkcaps' from the Dairy bottles were used, but thanks to companies like the now nonexistent World POG Federation, the simple game became an overnight fad that spawned an entire industry for years.
The game basically consists of taking a slammer and slamming it down onto a stack of Pogs that are stacked on a mat. You do this until either your or your opponent's Pogs have all been flipped over. There are variations to the rules, but these are the basics of it.
The game is simple and rather fun. POG The Game is a nice packaging of the game, with all the components needed to play it according to World POG Federation rules and with their official merchandise.
