Introduce the rules of darts game

The most commonly used competition rules in Europe and the United States, formal domestic and international competitions generally adopt this rule.

It gets its name from the fact that games always start at 301 or 501 points. In informal competitions, 701 or 1001 points are also used. The rules are briefly described as follows:

Before the start of the game, each player throws a dart, and the one closest to the center throws first. This is called bull's-eye throwing (see the ADO rules for the strict definition of bull's-eye throwing).

Multiple players take turns playing, throwing three darts in each round. The points scored in each round are subtracted from his total score. The first player to reach exactly 0 points wins.

The dart that each player ends the game with (not necessarily the third dart) must hit the double zone, which is called Double-Out.

If a player's score becomes negative after throwing a dart, his score for this round will not be counted and the number before the start of this round will remain. This is called Busted. If the game stipulates that "doubling out" is required, then if the score is reduced to 0 points but does not hit the doubling area, or if it is reduced to 1 point (doubling out is not possible at this time), it is also considered a blast dart.

Once the dart bursts, the player's round of throwing is over. Even if the three darts have not been played, his score returns to the score before the start of the round; it is his opponent's turn to throw .

For beginners, formal 501 competition is difficult, especially doubling up can be quite strenuous. You can try a simplified straight-in, straight-out 301 match. Straight-In/Single-In means that scoring can start from the first dart; Straight-Out/Single-Out means that the last dart does not have to be hit in the double zone Inside.

However, straight-in and straight-out games don't have many changes and tend to be monotonous; while doubling-out games require many techniques and require precise calculations in order to accurately and quickly double-out. Thank you!
