Featured Puzzle: Aquariums #1 – Aegir Sea Festival
In Norse mythology, Aegir was a Frost Giant that was also god of the sea. He was also the brewer for the Asgardian pantheon. One of his better-known feats is that when emptied, his mugs would magically refill with more ale.
To celebrate this ancient sea god, I wanted to showcase a Aquariums puzzle. The key to figuring these out is to think about how water flows. Shade cells in some regions to represent water inside them.
- Numbers outside the grid indicate how many water-filled cells exist in that row or column.
- Water flows down and to either side, unless stopped by a region wall.
- There are no pockets of air underwater. When a cell is known to hold air, all cells above it must also contain air.
- If water exists in an upper area of a region, other cells in the region at the same level must contain water, unless completely walled off so water couldn’t flow that direction. See the diagram below of an example solve to help understand this concept.
In the highlighted aquarium, the water is contained in 3 different areas that can’t flow to each other. Notice the water level is the same across each part.
Be on the lookout for a future Aquariums Solving Guide.
