Display Screen with Transitional Graphical User Interface of a Gaming Machine

FIG. 1 is the first image in a sequence for a display screen with transitional graphical user interface of a gaming machine showing my new design;

FIG. 2 is a second image thereof;

FIG. 3 is a third image thereof; and,

FIG. 4 is a fourth image thereof.

The appearance of the graphical user interface sequentially transitions between the images shown in FIGS. 1 - 4 . The process or period in which one image transitions to another forms no part of the claimed design. The outermost broken lines showing the display screen form no part of the claimed design. The remaining broken lines showing portions of the transitional graphical user interface form no part of the claimed design.
