Comment jouer a Sagani sur BGA

About Sagani, from BoardGameGeek:

Welcome to Sagani where achieving harmony between the natural elements of Earth, Water, Air and Fire is the central goal of the spirits that populate this world. These spirits spend most of their time in their vessel-like dwellings. But when the elements are put in balance, the spirits emerge from their vessels and show themselves in their full form. Each spirit embodies one of the four elements and influences the harmony between them. In Sagani, as you and your opponents create this colorful, harmonious world by employing your Sound discs, the spirits become fully visible. Every spirit that shows itself also brings you a step closer to victory. -description from the publisher
