About This Game

Logic Islands is a formal logic puzzle inspired by Nurikabe and Islands of Insight, and it is the deepest thinking game in this collection. The base rules come from classic Nurikabe: create islands of exact numbered sizes while keeping all walls connected as one continuous mass. From that foundation, six unique worlds introduce escalating mechanical complications — ice blocks, one-way arrows, Yin-Yang connectivity rules and special orb mechanics — across 240 hand-picked puzzles, each chosen rather than generated. The controls scale with the sophistication: toggle cells between island and wall, fill connected areas with double-clicks, switch draw modes, undo and restart as needed. This is genuine logic training with a long curriculum. For serious puzzle minds only. Free to play online, no download.
