Abstract
A spelling game including a grid of randomly selected letters arranged in a columnar form on a cylindrical surface of a writing instrument, cosmetic case, cigarette lighter or similar item of a type which is normally carried or kept readily accessible by most individuals while working, traveling, attending school, or pursuing other daily activities. Rotatably and longitudinally slidable over the grid is a generally tubular cursor having a plurality of differently sized apertures, each aperture defining a window through which a group of letters may be viewed. In using the game, the cursor is moved over the grid to any one of a number of possible positions in which a group of letters is exposed through each viewing window, with as many words as possible then being spelled using the letters visible through one of these windows. The game may be played by one or more players.
