How to play Aquarium
Aquarium splits the grid into bold-outlined regions, each one an aquarium. Fill each aquarium with water so every row and column total matches the clue along its edge.
Water always sits at the bottom of an aquarium and rises as one connected level, even when the aquarium bends or splits into separate arms. Use the exclude (×) mark to rule out cells as you narrow down where the water line falls.
