Nurikabe - Deductive Puzzles

HOW IT WORKS The board is divided into regions, each with its own color. Shade (tap) squares so that: - Every region holds exactly two shaded squares. - Every shaded square touches exactly one other shaded square along an edge. Shaded squares come in pairs, like dominoes, and two dominoes never touch along an edge (corners are fine). - The size of each region is your only clue. Every puzzle has exactly one solution. LEARN BY DOING A short hands-on guided tutorial teaches the rules on tiny boards, one idea at a time, and ends with a puzzle with hints if you get stuck.
