Game involving estimation of spatial relationships

摘要

A board game involving the establishment of spatial relationships and measurement thereof to determine the correctness of the estimation. The establishment of a spatial relationship is accomplished by moving a marker along a rectilinear element and/or moving a marker about the center of a circular element to establish, respectively, or alternatively, a spatial relationship between an end of the rectilinear element and the first-mentioned marker and/or the angle made by the marker about the axis of the circular element with reference to, for instance, a radial line extending from the center of the circular element. Alternative ways of playing the game are disclosed. A board having the rectilinear and circular elements may provide marked areas around the periphery thereof which are imprinted with indicia directing the players to estimate a length or an angle preset on the elements with the markers and of which there may be a plurality. Dice may be used, as an element of chance, to direct a player to move a player piece from a starting marked area along the board periphery to another marked area or a number of marked areas from the starting marked area indicated by the number of dots on the die or dice he has thrown. Alternatively, cards, turned face down, may be used and picked by a player, such cards requiring the player to set an angle within the circular element and marker, or to set a rectilinear spatial relationship with the rectilinear element and marker, by estimating where the markers should be placed. In either event, the actual spatial relationship set on the element with the marker is measured by a ruler or a protractor to determine the correctness, or near- correctness, of the player's estimate.
