In the game Rumis the players construct an Inca building with their stones. All players receive three-dimensional pieces made of wood, which they will try to position adjacent to their already placed pieces of their own colour. All of their own pieces are of different shape, which is a challenge to the three-dimensional imagination.Cubic, wedge-shaped or pyramidal volumes are different building limitations, which are imposed by the various building scenarios. Playing RUMIS you will find that no game is similar to any previous one. Once your mind has mastered the puzzling shapes of the RUMIS pieces, you will explore the depth of tactical and strategic possibilities offered.The rebrand by Educational Insights is labelled 1 to 4 players on the box, suggesting there's a solitaire mode for that edition - BoardGameGeek
