What areas do the large and small sectors on the dart target represent?

What areas do the large and small sectors on the darts flights target represent? There is a circle of 20 numbers corresponding to 20 partitions on the dart board. Each number corresponds to a sector, which represents the score in this sector, and each sector has 4 grids, which correspond to a certain multiple from outside to inside, which are 2 times, 1 time, 3 times and 1 time respectively. For example, hitting the outermost grid of the sector of 20 is 40 points, and so on.

1. Score area: this area is the score area of the calibration score of the outer ring of the dart tray.

2. Double area: the narrow ring of the outer ring of the dart board is twice the score area.

3. Triple zone: the narrow ring in the inner circle of the dart board, which is three times the score of each score zone.

4. Outer circle center: this area is 25 points (green).

5. Inner circle center: this area is 50 points, and this area is the double area of the outer circle center (red).

6. The 20 zone of the dart tray should be directly above the darts shafts tray (in the direction of 12 o'clock in real time) and black, while other score areas are crossed and divided into two colors from 20, clockwise as 1, 18, 4, 13, 6, 10, 15, 2, 17, 3, 19, 7, 16, 8, 11, 14, 9, 12 and 5.

An interesting thing about darts is that the numbers on the target are arranged alternately according to the size, and the larger the number, the smaller the numbers on both sides, which has a great impact on the players' competition strategy and final results. It is said that the irregular number arrangement of dart target was first invented by a carpenter named Brian Gamlin in 1896 and has been used until today. It is estimated that the carpenter made it only by feeling at that time. In this regard, someone once wanted to mathematically verify whether this number arrangement is the best in theory, and designed the so-called mathematical optimization dart target. If the 20 numbers on the target are arranged and combined, there are as many as 1.2 billion kinds. What is the best? Different people have different opinions. A simple standard is to make the difference between each number and the two adjacent numbers as large as possible. The sum of 20 numbers and the absolute value of the difference between the left and right neighbors is the largest. Such a target may be the most scientific. According to the calculation, the maximum possible value added together is 200, while the target we usually use is 198 darts.

If you observe carefully, you will find that there are very small scores around high scores or double scores, that is, if you want to get high scores, you have to risk getting low scores, and the higher the score, the greater the risk. This not only increases the difficulty of the game, but also enhances the game and the unknown, and greatly improves the fun of darters.
