Bolo palma is a variant of bowls that originated in and is played throughout the region of Cantabria, north of Spain.
[1] The game was also spread to neighbouring areas of eastern Asturias and northern Palencia.
Here, there are 9 wooden bolos (pins), made out of birch or hazel, with a metal base (argolla or anilla), about 45 cm tall and 5 cm diameter, weighing between 550-630 g. These are placed on pegs in a 3x3 square exactly straddling both zonas.
[1] The third section is the zona de birle, a 12m long area where the second phase of the game is played.
The player then launches the ball upwards into the air, employing a number of different techniques depending on whether the emboque is to the left or the right of the caja.
