About Logic Islands
Logic Islands is a thoughtful puzzle game rooted in the classic Nurikabe tradition, where you carve isolated islands of numbered cells out of a shared grid of walls. Each puzzle requires you to place exactly the right number of cells in each island while ensuring the remaining wall cells form one continuous connected body — a constraint that sounds simple but generates beautifully complex deductions as puzzles grow larger. The game spans six distinct worlds, each introducing new mechanical wrinkles that evolve the base ruleset in surprising directions. Whether you are a seasoned Nurikabe solver or completely new to the genre, Logic Islands offers a rewarding progression from approachable to genuinely challenging.
How to Play
Tap or click cells to designate them as island or wall. Each numbered cell represents an island of exactly that size — fill in the correct number of adjacent cells to complete it. Wall cells must all connect into a single unbroken group, and no two islands can touch each other. Use logic to eliminate possibilities rather than guessing.
Tips & Tricks for Logic Islands
- Start each puzzle by marking cells adjacent to a number-1 island as walls immediately — those cells can never be part of any island.
- When a large island number is surrounded by walls on most sides, the remaining direction is forced — use this to lock in island cells early.
- Work on wall connectivity throughout the solve rather than at the end; it is easier to spot illegal disconnections before the grid fills up.
