HingeHarbor

HingeHarbor is a spatial logic puzzle that challenges your ability to think in connections and cycles. Each level presents a set of hinge nodes scattered across the board. Every hinge holds two line segments that rotate together when tapped. Your goal is simple to describe but satisfying to solve: rotate the hinges so that all line segments connect into a single, unbroken closed loop.

Gameplay is intuitive and tactile. Tap any hinge to rotate its connected segments by 90 degrees. Watch how each rotation changes the connections between segments, and plan your moves to gradually shape the chaos into a perfect circuit. The number of steps you take is tracked against a target and an optimal solution, encouraging you to find the most elegant path to completion.

Features 40 progressively challenging handcrafted levels. Early levels introduce the core mechanics with a small number of hinges and generous step limits. As you advance, the puzzles grow in complexity with more hinges, locked hinges that cannot be rotated, and one-way hinges that can only be rotated once. Each additional mechanic adds a layer of strategic depth without overwhelming the player.

A medal system rewards efficient play. Complete a level within the target steps to earn bronze, match the optimal solution for silver, or beat it for gold. Replay any completed level at any time to improve your score and chase the perfect solution.

The visual design is clean and minimal, focusing attention on the puzzle itself. Segments that successfully connect glow with a distinct color, providing clear feedback on your progress. When you complete a level, the entire loop lights up in celebration.

No internet connection required. No ads. No permissions. Just pure puzzle-solving satisfaction for moments of focused thinking.
