The standard format involves each player starting with a score of 301. The objective is to be the first to reduce that score to exactly zero. Players take turns throwing three darts, and the sum of their scores for each turn is subtracted from their remaining total. A critical aspect is the requirement to finish on a double, meaning the final dart thrown must land in a double segment of the dartboard, bringing the score down to zero.
This particular variant is popular due to its relative simplicity and accessibility, making it suitable for players of varying skill levels. It provides a good balance between requiring accuracy and strategic planning regarding how to approach the final stages of the game. Historically, similar point-based games have long been a staple of darting culture, providing a structured and competitive format.
