Divide the table into islands with numbers, so that the sum of the numbers on each island is equal to the number of island cells, subject to certain rules.
In the nurikabe-pair, you need to draw lines (symbolize rivers), so that the table is divided into empty sections with numbers (symbolize islands), observing the following rules:
The river must be solid, i.e. all colored cells must be connected into a single chain.
Shaded cells cannot form a 2x2 square (or bigger).
Each island must contain two numbers, the sum of which is equal to the number of cells on the island.
