Abstract: A bowling device comprising a base, at least one transparent overlay, and fasteners for supporting the overlay on the base for limited sliding movement relative thereto is disclosed. A representation of a bowling alley and ten bowling pins is provided on the base. A representation of a path of body travel and a path of ball travel corresponding with one of a variety of bowling styles (i.e. straight ball, hook ball, etc.) is provided on one or more overlays having first and second ends.Slots are provided in the first and second ends of each overlay, at positions adjacent to the end of the path of ball travel and the beginning of the path of body travel. The slots are oriented substantially transversely to the path of ball travel. Pins are secured to the base so that a portion of each pin engages the edges of the first and second slots.
