El patacó is a traditional game played by children in Catalonia in which the patacons are turned upside down, hit with the palm of the hand and, if they turn around, they win.
It is a game of aim, dexterity and luck that can be played both on the street and at home and there are many game modes. Its origin is in the word "patac" ‘violent and sudden strike’.
See main article: Milk caps (game). The traditional patacó is a more or less square piece made with a couple of pieces of cardboard usually made from a Spanish playing cards or a box of matches, folded and fitted together the way they can be distinguished between front and back.
The construction procedure begins by splitting a card in half, leaving two equal parts. The two pieces are then placed on top of each other in the form of an angle of 90 degrees and the piece is bent in a horizontal position backwards and then folded forward again. The same is done with the vertical piece and finally the free piece is fitted in the slot formed by the other folds. The two sides of the patacó must be different in order to distinguish the front and the back faces.
A modern version of patacons have been distributed internationally under the name of Pogs or Tazos.
For many years it has been one of the most representative toys of generations of grandparents in Catalunya. It has been a major toy for children until the late 1960s, as it could serve as both a toy and a currency for children, what made the patacó a game piece with a high value for children. It was often bet to get more at the risk of losing the ones you had. To build them, the boys and girls waited for the adults and especially the grandparents to throw away the already used cards from their games in the cafe. Usually when the grandparents' widely used or marked cards (for cheating) were no longer used, they gave them to the children who built their patacons. Children also collected the empty boxes of matches that the old smoking people left in the coffee tables.
