Nurikabe: Islands & Walls

Nurikabe is a captivating logic puzzle where you partition a grid into islands by placing walls between clues. Each island must contain exactly one clue, and the number of squares in the island must match the clue's value. Walls must form a continuous path and cannot create 2x2 or larger blocks. The challenge is to deduce the correct placement of walls using pure logic, without any math.
