The mark consists of a five-sided, pentagon-shaped line forming an outermost border colored in dark teal. Immediately within the outermost border is a contiguous five-sided, pentagon-shaped line, forming an inner border, that is thicker than the outermost border in dark teal described in the previous sentence and that is in deep teal. Within the deep teal inner-border is a pentagon shape, whose background is entirely filled with dark teal, the same color as that of the outermost border. Appearing within the deep teal inner-border and laid over the dark teal background of the pentagon shape enveloped by the deep teal inner-border is a stylized depiction of a castle tower depicted with a dark teal outline. The stylized castle tower shape is composed of stylized shapes depicting squares, rectangles, and other quadrilaterals made to appear like bricks. These squares, rectangles, and other quadrilaterals, forming the castle shape and representing bricks, are shaded to represent a shadow over the castle tower structure such that the squares on the leftmost edge of the tower are colored grey and shift colors from the left side of the castle shape towards the right side of the castle shape in the following sequence to depict the darkening shadow: grey, light grey teal, and deep teal. At the top of this stylized castle shape is a series of vertical rectangles intended to depict a crenellated fortress. At the left and right sides of the castle tower shape are positioned two symmetric shapes consisting of an outer-curved line, similar to the sides of a circle, whose extremities turn at sharp angles towards the center of the mark and continue by forming two straight lines, which are further connected by a third straight line. The symmetric shapes described in the previous sentence are colored yellow and look like a sun rising or setting behind the castle shape. In the middle of the stylized castle shape is a shape formed by a semi-circular arch at the top, two parallel vertical lines on both sides and extending below the semi-circular arch, and a horizontal line intersecting the two parallel vertical lines at the bottom of this shape; this shape depicts a lancet window. The negative space formed by the lancet window shape is shaded yellow to depict another portion of the stylized sun shape shining through the lancet window from behind. Below the stylized tower are four lines joined to form a parallelogram at the base of the tower shape; the negative space of the parallelogram is shaded grey. The parallelogram depicts a chess board square. Beneath the grey parallelogram is the word "CASTILLO" in a stylized font consisting of yellow letters with teal shading. Beneath the word "CASTILLO" is the word "GAMES" appearing in the same stylized font in a smaller size, consisting of grey letters with teal shading in the same pattern as the shading within the word "CASTILLO".
