NN44Harbor

Find the route hidden in the evidence. EchoHarbor is a quiet logic puzzle for short, focused sessions. Each board presents a field of numbered beacons, a starting point, a destination, and a small set of visible clues. Read the relation, form a theory, then choose the next beacon and watch your confirmed route take shape. Every choice has a reason. Correct selections reveal new evidence and extend your route. A wrong turn uses a tolerance marker and explains whether the conflict came from heading or signal count, so you can adjust your reasoning instead of guessing blindly. Your first chapter introduces alternating headings across a compact 4x4 board. When you want a different test, open a random challenge with a fresh route structure and two active relations. Use up to two hints when you need another piece of evidence, or undo your most recent confirmed step while you compare possibilities. Finish with fewer steps and fewer hints to improve your personal record. Local progress keeps your best route and completed-game count on the device, with no account, connection, or external service required. Features: • Short offline logic sessions • Clear beacon board with numbered choices • Evidence-based hints and useful wrong-turn feedback • Undo for the latest confirmed route step • Chapter practice and random challenges • Local best-step tracking
