A gaming machine provides an operation unit, a display unit, and a control unit. The operation unit is an operation of the player. The display unit is operably coupled to the operation unit and is configured to display first and second display areas. A number of free bonus may be awarded during a primary game. During the free spins, any occurrences of a predetermined symbol is copied to the second display area. After the free spins, a secondary bonus may be provided using the second display area and the copied symbols.
