In this falling-block puzzle game, a small girl pushes segments of water pipe down a vertical shaft. This shaft is the field of play. The player must quickly rotate and place the tiles to catch and conduct a continuously flowing stream of water from pipes on one side of the shaft to the other. When the player successfully links an inflow pipe on one side of the shaft to an outflow pipe on the other side, a row of tiles disappears, and the player earns points. By clearing the requisite number of rows, the player proceeds to the next game level.
