I was playing Patience (also known as Solitaire).

All the cards were red.

The word “Olmec” also refers to the rubber balls used for their ancient ball game. Early modern explorers applied the name “Olmec” to the rediscovered ruins and art from this area before it was understood that these had been already abandoned more than a thousand years before the time of the people the Aztecs knew as the Olmec.

Rubber ball games have great antiquity throughout the Americas, and the recent discovery of several rubber balls at the Olmec site of El Manati, near San Lorenzo, confirms that the game was played by the Olmec. Archaeologists working at La Venta twenty years ago discovered what they hypothesized were the remains of a ball court there, and it is possible that such ball courts were also part of the architecture at Olmec centers.

The Olmec were perhaps the originators of the Mesoamerican ballgame, prevalent among later cultures of the region and used for recreational and religious purposes. They were playing ball before anyone else has been documented doing so.
