About

Knotspan: Topology Trials is a focused, fully on-device app. A tactile topology puzzle game where loops, crossings, twists, and linked rings obey consistent rules, and every solution can be replayed as a clean sequence. KEY FEATURES - Drag a strand segment to propose a local move. - Crossing order and loop continuity are always preserved. - Legal simplifications reduce the diagram without cutting. - Expert trials require matching invariants, not just appearance. - Sixty complete campaign trials - Original offline fieldbook and audio cues - Local progress and records with no account ONE-TIME AND PRIVATE - One paid download; no subscription or in-app purchase - No account, advertising, analytics, tracking, or developer-operated backend - Core features and bundled content work offline - Work remains on device unless you deliberately share or export it through an Apple system interface Knotspan is a fictional entertainment game. Its rules, scoring, physics, maps, evidence, and terminology are designed for play and are not professional guidance.
