It is played in a court shaped as a large level rectangle, built of flattened earth (typically rich in sand or clay), clear of trees or visible obstacles.
On occasion, an internal string perimeter fitted at no more than 20 centimetres (8 in) from the enclosure signals valid gaming ground.
The solid balls (roughly 15 centimetres (6 in) diameter, made of synthetic material) are colored red and green respectively to separate each team.
The small steel or iron ball called Mingo has a diameter no greater than 5 centimetres (2 in) and is used as a marker.
Points are awarded in the following fashion: the judge identifies the winning color as the ball that is closest to the Mingo.
Though a simple game, experienced bolas criollas players display great skill at their throws.
