What is calva? While this game is only played in Spain, it remains one of the most popular in the country.

Believe it or not, the game can be traced back to pre-Roman times.

In the early days, players threw stones at a bull’s horns. Over the years, the horns were replaced by a piece of wood, known as a calva. Additionally, the stone has been replaced with an iron cylinder, known as the marro.

The goal of the game is simple: players attempt to knock down the calva by throwing the marro at it from 14.5 meters away.

Each player has 25 attempts to hit the calva. Before starting, players are given two practice throws.

A calva field is approximately 25 meters long and five meters wide.

This basic calva information shows not only that this game has a long history, but that it is easy to play.
