Abstract
The modular terrain for a playing structure, such as a toy building set, includes a plurality of terrain pieces. Some of the terrain pieces have a flat exterior edge. The flat exterior edge is only matable with a flat exterior edge on another of the terrain pieces. The flat exterior edge has spaced longitudinal end points. The flat exterior edge has no change in height between the spaced longitudinal end points. The distance between the spaced longitudinal end points of the flat exterior edge is one of Y, .sqroot.2Y and 2.sqroot.2Y. Some of the terrain pieces have a hill exterior edge. The hill exterior edge is only matable with a hill exterior edge on another of the terrain pieces. The hill exterior edge has spaced longitudinal end points. The hill exterior edge has a change in height between the spaced longitudinal end points of X. The distance between the spaced longitudinal end points of the hill exterior edge is Y. Some of the terrain pieces have a slope exterior edge. The slope exterior edge is only matable with a slope exterior edge on another of the terrain pieces. The slope exterior edge has spaced longitudinal end points. The slope exterior edge has a change in height bet…
