Doll machines are a common type of gaming machine, usually with various types of dolls or other prizes placed inside a glass cover. Players need to invest a certain amount of coins or tokens and operate control levers or buttons to control the position and grasping force of the robotic arm as accurately as possible, in order to try to capture the doll or prize within the specified time. Doll machines are widely used in amusement parks, shopping malls, game halls, and other places, and are often used as a mixed form of entertainment and gambling to catch dolls.
