Darts is a game in which players throw small missiles at a circular target fixed to a wall. The object of the game is to score points by hitting certain areas of the target.
The standard dartboard is divided into 20 sections, each worth a different number of points. The largest section, worth 20 points, is the outer ring. The next largest section, worth 19 points, is the inner ring. The smallest section, worth 1 point, is the bullseye.
There are many different games that can be played with a dartboard, but the most common is 501. To start 501, each player throws three darts at the board and aims to score as many points as possible. The player with the highest score after three darts goes first. From then on, players take turns throwing three darts apiece and subtracting their score from 501 until one player reaches zero (or goes out). That player wins the game
