Abstract: A score system is applied to an electronic device. The electronic device includes a storage unit storing a mapping relationship between touch points and score values, and a touch screen generating input signals. The control system includes a number of processing units and a number of modules which are collections of instructions executed by the number of processing units. The number of modules includes a gesture recognition module recognizing a gesture in response to the input signals and determines all coordinate values of the gesture, a comparison module comparing the coordinate values of the gesture with coordinate values of the plurality of touch points and a calculation module obtaining a score value of each touch point of which the coordinate value is equal to the one of coordinate values of the gesture and calculate a total score of the score values.
