PHA: Water Beds
The grid is divided into areas called "aquariums".
Add water by shading cells (paper) or clicking cells (online).
The water level in each aquarium must be the same across its full width. Some aquariums remain empty.
Numbers indicate how many cells are filled horizontally and vertically.
Adding water causes some letters to float up one or more cells. Read only these letters left to right and top to bottom.
