The game is divided into two teams, with four people in each team. Take turns throwing stones and guessing that the loser throws the copper coin first. Each game (end) ends after each team alternately throws the ball. Each team throws two balls respectively, and eight people * * * sixteen balls. The scoring method is: the stone ball located in the house and closest to the center of the round base scores. Each stone ball of the team located on the round base and closer to the center of the circle than all the stone balls of other teams can get one point. Skip should lead the game. When a player throws a ball, the main player should hold a broom as the goal of pitching. The commander should also indicate the turning direction and the sliding distance of the stone ball, so that the players can know the purpose of throwing the ball, so that the ice sweeper can decide how to brush the ice, because brushing the ice can increase the sliding distance of the stone ball and reduce its forward curve. Mark the sideline of the field: any stone ball that touches the sideline is considered out of bounds and should be removed from the field immediately. House: a piece of ice, one at each end, consists of several concentric circles. Hack: Located between the edge of the court and the circular base, players can kick back and forth when pitching. Service line: when pitching, if the stone ball has passed the center line of the pitching area, it can't be thrown again. After the stone ball is thrown, your own ice brush can brush the ice before the stone ball passes through the center line of the target area; After that, the opponent will have the right to brush the ice to make the ball leave the center. Arch line: When throwing the ball, the player must leave the ball before the hurdle line in the throwing area. After throwing the ball, if the stone ball stops before it completely crosses the fence line of the target area, the ball is considered out of bounds. But if it has collided with the ball in the game, it is unnecessary for the ball to cross the hurdle completely. A game needs two groups of stone balls, each with eight balls. These balls should be colored so that they can still be easily identified at the other end of the ice course. Traditionally, in the first game, the team that has no right to throw the last ball can choose its ball color. Position of players In order to avoid crowding, the rules of the game also stipulate the position of players: for non-throwing teams, the main commander and No.3 can stand behind the baseline of the target end, and the main commander can also stand behind the main commander of the throwing team. The second-ranked thrower can stand near the backboard, while other players can stand behind the bottom of the rink or between the two hurdles. Throwing team: The main commander (or deputy commander) with an ice brush can stand anywhere behind the center line of the target end. Under special circumstances, if the thrower fails to release the ball before it reaches the throwing end fence, the opposing team has the right to choose the way to handle the ball: (1) still regard the ball as valid, (2) regard the ball as out of bounds and put all the balls hit by the ball back in their original positions. Accidentally touching the ball When a stone ball slides, it is considered as touching the ball if the player of the throwing party (usually an ice brush) accidentally touches the ball with his body, clothes or an ice brush. After the taxiing is completed, the opposing team can punish the ball in one of the following three ways: 1, and still regard the ball as valid; 2. Regard the ball as out, and put all the balls hit by the ball back in their original positions. 3. If the balls are not touched, estimate the position of each ball in the field. And move each ball on the court to its estimated position. The ice brush of the thrower can brush the ice for his own stone ball moving between the two center lines. However, after the center line, only one player of each team can brush ice for his own stone ball, and only the main player can brush ice for the other team's stone ball. Score the team with the stone ball located closest to the center of the round base in the house. Each stone ball of the team located on the round base and closer to the center of the circle than all the stone balls of other teams can get one point. Before moving any stone balls, the third player in the two teams should know the score. If two stone balls belonging to different teams are not sure which one is closer to the center of the circle, unless the other stone ball is closer to the center of the circle, the game will be considered as no score.
