Shanghai

In this game the player throwing 3 darts in each of the 20 turns should try to score as many points as possible or win a "Shanghai".

Only hitting the numbers the same as the turn number lets players increase their score. In the first turn the points are scored for hitting number 1, in the eleventh - number 11, in the twentieth - number 20 and so on.

Players hit the numbers from 1 to 20 in sequence omitting the "bull's eye". The inner narrow board ring counts for three times the number hit, the outer narrow board ring counts twice the number hit.

In order to win, players should score the most points after the 20th turn or win a "Shanghai", which means hitting a the number the same as the number of the turn three times in one turn and within a section of a number scoring x1, x2 and x3 in any sequence.

Such a combination finishes the game and makes the player who has won a "Shanghai" a winner regardless the results of the other players. If the turn limit has ended, and both players have the same number of points, the one who started the game wins.
