CopyCat is a geometric game where the goal is to use the patterned faces of a polyhedron to create a Mosaic. The polyhedron's orientation is manipulated by rolling. Sequences of rolls can exhibit properties like non-commutativity, non-associativity, and non-closure. This paper presents visual explanations of these properties in the context of rolling polyhedra. Maps depicting the sequences of rolls use the geometric properties of the map to exhibit the regularities in the sequences. Currently, the maps can be used as tools external to the game but the ultimate goal of these visual explanations is to use them to guide the design of new CopyCat tools and interfaces that promote understanding of mathematical subtleties of rolling sequences.
