A game controller, comprising:

• a casing comprising an upper cover and a lower cover, wherein at least one operation hole is formed in the upper cover;
• a base comprising a main body, at least one driving module and at least one first position-limiting structure, wherein the main body is fixed on an inner surface of the upper cover, the at least one driving module is installed on the main body, and the at least one first position-limiting structure is disposed on the main body;
• a movable seat disposed over the base, and comprising at least one linking part and at least one second position-limiting structure, wherein the at least one linking part is connected with the corresponding driving module, and the at least one second position-limiting structure cooperates with the corresponding first position-limiting structure, so that the movable seat is movable along the at least one first position-limiting structures;
• a signal control module installed on the movable seat;
• and
• an operation element connected with the signal control module, wherein a portion of the operation element is exposed to the at least one operation hole,
• wherein the at least one driving module drives a position-limiting movement of the movable seat relative to the base through the at least one linking part, so that an altitude of the operation element is adjustable.
