About the game
Aqua Fill is a calm logic puzzle about fish tanks. The grid is split into tanks of odd shapes. Water in a tank always settles from the bottom with a flat surface, so if one cell of a row is wet, the whole row of that tank is wet, and so is everything below it inside the same tank. The numbers on the right and along the bottom say how many water cells each row and column must hold.
Tap a cell and its tank fills right up to that row with a slosh. Tap the surface again to mark the row above as air. Rows and columns turn green when they're right and red the moment they can no longer work. Thirty puzzles grow from 5x5 to 8x8, all with exactly one answer, and later ones need you to test a choice and watch it fail.
