Ferrostiga

An interactive steel fatigue life themed puzzle application combining engineering education with engaging gameplay. Features three core modes: a card elimination challenge where players match triplets of symbols from a shuffled grid into seven bottom slots, a timed card recognition mode testing observation and recall under pressure, and a structural engineering knowledge quiz covering S-N curves, stress ratios, crack propagation, and weld defects. The app includes a comprehensive achievement system tracking milestones across all modes, detailed game history with filtering, and multiple difficulty levels. Styled with an industrial steel-blue palette featuring gradient accents, smooth spring animations, and intuitive touch interactions throughout.
