The game card includes a transparent substrate; and a transparent color layer formed on the transparent substrate and comprising a game pattern formed by overlapping a hidden portion and a cover portion, wherein the hidden portion has at least two different colors for blocking the light with the specific wavelength range and the cover portion does not has the color for blocking the light with the specific wavelength range, whereby when the transparent color rendering sheet is overlapped on the game card, the cover portion reveals a lighter color similar to the predetermined color after rendering with the transparent color rendering sheet, and the hidden portion reveals a darker color after rendering with the transparent color rendering sheet.
