Open Space with Rocks Set A

Publisher's blurb: The Open Space with Rocks group of Naked Geomorphs contains 8 tiles, each with open space (S) at all six positions, and islands of rock. Sets A and B are completely interchangeable. Indeed, all tiles of this group are interchangeable. Tile S1A can be replaced with tile S1B or tile S8A without changing the basic structure of your map. Set A has smaller and somewhat more numerous rocky islands than Set B.
