A slingshot simulator includes a housing, a trigger mechanism and an elastic band. A window is defined on the housing, a switch is arranged at one side of the window, and a connector electrically connected to the switch is disposed in the housing. The trigger mechanism is arranged on a side outer surface of the housing and at one side of the window corresponding to the switch. The trigger mechanism is able to move relative to the switch to alter an electrical status of the switch. The elastic band is connected to the trigger mechanism and able to actuate the trigger mechanism to move relative to the switch. The electrical status of the switch is altered while a user pulls the elastic band to simulate a bow-shooting operation, and a corresponding signal is delivered via the connector.
