You've come to the lake hoping to witness a rare and beautiful sight. Lake lilies only open their flowers in the rain, and only rarely do all eight types of lilies bloom simultaneously. The goal of A Gentle Rain is to place the lake tiles so that all eight types of lilies bloom before you run out of tiles and the rain ends.
Place each new tile you draw next to a tile already in play, making sure the colors of all adjacent tile edges match the tile you're placing. Each time you complete a square of four adjacent tiles, a flower opens between them.
Keep score, or don't.
