The mark consists of the stylized word "RiGMA" above the stylized word "ROLLER". The letters are in the following colors: "R" is blue, "i" is light blue with a yellow triangle in place of the dot, "G" is red, "M" is orange, "A" is yellow, "R" is orange, "L" is light blue, "L" is red, "E" is yellow, and "R" is blue. Each letter has dots in the same color as the letter but in a darker shade. The "O" is in the form of a black and white die. Below the word "ROLLER" is a blue curved line that forms a mouth and a red tongue. All of the foregoing appears on a black background with a periwinkle outline.
