The Evesham League game has been structured upon the Long alley-Western type of game, whereby 9 pins are formed in the shape of a diamond facing the player The pins are normally placed upon a steel plate, which bear markings to identify placement of each pin The League allows pins to be made from either wood or high density polyurethane and the design is based upon the 10" Gloucester pin Balls can be made from wood or composite material and are approximately 4 ¾ " in diameter The League stipulates that the front pin facing the player should always be marked and is known as the 'King' pin. The two pins next to the 'King' pin are also marked and these are known as the 'Quarter' pins All the alleys within the Evesham League are wood and are based upon general guidelines in terms of length and width.
