About Logic Islands
A logic puzzle game inspired by Nurikabe and Islands of Insight. Create islands with exact numbers while keeping walls connected. Navigate through 6 unique worlds with different rulesets - from Classic Nurikabe to advanced mechanics like Yin-Yang connectivity. Each world introduces new challenges with ice blocks, one-way arrows, and special orb mechanics across 240 hand-picked puzzles.
The genre lives on a clear goal, progress you can feel and quick loading. Logic Islands understands that, and it shows in the first minute of play. Playing it works your timing and coordination, which is a large part of why the "one more round" feeling is so strong.
