This note studies the relationship between the global game and the generalized potential game approaches. We provide a non-degenerate example of a symmetric 3×3 supermodular game that has no monotone potential maximizer (MP-maximizer). Since the global-game solution for symmetric 3×3 supermodular games is independent of the noise distribution, this implies that MP-maximizer is not a necessary condition for global-game noise-independent selection.
