A paving stone (10) is provided that can be laid in a plurality of open patterns, each presenting a different amount of drainage area, while retaining an interlocking relationship between adjacent stones of the pattern. In the preferred embodiment, the stone (10) can also be laid in a closed pattern, with no drainage areas provided other than the drainage at the boundaries of the stones. Each side surface (21-24) of the stone (10) has an odd number of faces (31-35), arranged in a stair-step shape. Preferably, each of the side surfaces (21-24) is symmetrical about the center face (33), and all sides (21-24), or at least opposite sides (21,23) or (22,24) are identical.
