Logic Islands is a logic puzzle game inspired by Nurikabe and Islands of Insight. The goal is simple but satisfying: mark groups of cells as islands so each numbered clue contains exactly that many cells, while marking the remaining cells as wall to form one continuous connected wall. You must also follow variant rules in each world, such as avoiding 2x2 wall blocks, preventing islands from connecting orthogonally, and obeying special mechanics like ice blocks, one-way arrows, and orb rules.
The game offers 240 hand-picked puzzles across 6 unique worlds. Worlds range from Classic Nurikabe to advanced rule sets that test pattern recognition, planning, and deduction. Gameplay uses a clean grid interface with multiple draw modes so you can mark a cell as island, wall, or unknown. Smart tools let you fill connected regions, undo moves, and restart a puzzle. Logic Islands suits casual players and logic fans who want focused brain training in short sessions.
- Objective: Create islands that match the numbers and keep the wall cells connected.
- Core mechanics: Exact-size island groups, connected wall, no 2x2 wall squares, and island separation rules.
- Variants: Ice blocks that freeze cells, one-way arrows that force expansion directions, Yin-Yang connectivity, and special orb interactions.
- Puzzle set: 240 curated levels with progressive difficulty and 6 themed worlds.
