FoldHarbor

Think one fold ahead in a quiet spatial puzzle built around paper, signs, and patterns. Explore 90 progressively challenging levels. Study the target, preview a horizontal or vertical crease, then fold when you are ready. Each move changes which marks meet and how they combine. Positive and negative signs cancel when they share a cell. Matching signs remain as a layered mark. Match every position, sign, and layer count before the fold limit runs out. Undo a fold, ask for a directional hint, pause to reconsider, or retry a puzzle. When a run ends, inspect the first mismatch and use what you learned to plan another approach. Chapters introduce larger grids, sign cancellation, layered marks, and longer fold sequences. Unlock levels in order, revisit completed puzzles, and keep a record of your fewest folds for each solved level. Your progress is stored on your device, and the core puzzle experience works without a network connection.
