Pogs is a game that was popularized during the early 1990s. The game is played using discs which are also called "pogs". The name originates from POG, a brand of juice made from passionfruit, orange and guava; the use of the POG bottle caps to play the game pre-dated the game's commercialization. The game of pogs possibly originated in Hawaii (Maui, Hawaii) in the 1920s or 1930s, or possibly with origins in a game from much earlier: Menko, a Japanese card game very similar to pogs, has been in existence since the 17th century. Pogs returned to popularity when the World POG Federation and the Canada Games Company reintroduced them to the public in the 1990s. The pog fad soared, and peaked in the mid 1990s before rapidly fading out.
Pog typically relies on two types of playing discs: pogs and slammers. Pogs are typically flat circular cardboard discs which are decorated with images on one or both sides. Traditional (or traditional-style) pogs are made of rougher cardboard, are printed with limited colors, and often have a staple in them (as they appeared when used as actual POG bottlecaps), while modern commercial pogs were stiffer, thicker and are often printed with colorful glossy imagery.
The other equipment that is used is a slammer: a heavier game piece often made of metal, rubber, or more commonly plastic which come in various thicknesses and weights, but are typically similar in diameter to pogs. Metal slammers are not allowed in some games because they are typically heavier than other materials, giving the player with the first turn an unfair advantage.
