Abstract: A play device or game in the form of circular top and bottom members having a group of individual transparent disks between the members, the top member having a cutout or window through which a section of all disks can be seen. The disks carry a group or pattern of opaque spots on their surfaces so arranged that the disks can be positioned to provide alignments of groups of spots on individual disks observable through the window so that the spots collectively define the outline of a letter, geometric figure, or other design. Methodology is provided by way of use of rectangular grids, each having spots arranged to represent a component of a letter or figure. The grids are identified by a number, and then tabulated to indicate the grid components that make up each letter or figure and are then used for positioning the opaque spots in the disks.
