A wagering game system can include a memory and a computing device in communication with the memory. The computing device can generate a representation of prismatic objects, each comprising at least four sides. The computing device can determine sets of indicia from a plurality of indicia, the sets of indicia individually corresponding to a respective prismatic object. The computing device can generate a user interface comprising the representation the prismatic objects arranged in a grid, each side for each prismatic object comprising indicia from a corresponding one of the sets of indicia. The computing device can rotate the representation. The computing device can stop rotation of the representation with a respective randomly selected side being shown on the user interface for each prismatic object. The computing device can determine a wagering game outcome based on the respective randomly selected side being shown on the user interface for each prismatic object.
