Hidden City is a hidden object detective adventure for players who enjoy cozy mystery games, search-and-find puzzles, story-rich quests and richly detailed scenes. Explore a mystical Victorian city, find hidden objects, follow clues, solve puzzles, meet unique characters and uncover magical secrets in the City of Shadows. Your next investigation awaits in a game where detective cases, beautiful search scenes, puzzle variety and magical events blend into one captivating mystery story. Look closer, collect clues and discover why every object, note and artifact matters. What will you investigate? Search atmospheric scenes filled with hidden items, evidence, notes, artifacts, keys, symbols, curiosities and visual clues. Every location invites careful observation and rewards players who love to find meaningful details in beautiful environments. Explore foggy streets, ornate halls, manor-like rooms, curious shops, gardens, arcades, laboratories and magical city districts. Each place supports the mystery and turns object search into part of the investigation. Which search modes can you play? Hidden City keeps the main investigation fresh with different modes designed to test your observation skills: • Words mode: Classic hidden object searching using text lists. • Silhouettes mode: Visual challenges based on object shapes. • Night mode: Focused searches in dim scenes using a spotlight. • Pairs mode: Matching identical or logically related objects to test your attention. These modes support players who enjoy search-and-find adventures, visual puzzles, detective games and finding hidden items through careful observation. Are there mini-games and puzzles? Yes. The core search mechanics are supported by puzzle modes that add variety without taking over the main experience. Take a break from the investigation and play through: • Spot the difference: Compare two scenes using sharp observation. • Match-3 levels: Crystal and gem matching for satisfying puzzle breaks. • Brain teasers: Logic mini-games, memory challenges and story-driven riddles. This mix works well for players who want a detective game with brain teasers, a mystery puzzle with clues or a search-and-find adventure with match-3 elements. How does the story unfold? Follow narrative-driven quests, character stories, special cases and event investigations. Assemble artifact collections, solve anomalies, complete requests and unlock rewards that help you continue your detective journey. Every quest connects detailed scenes, puzzle challenges, magical discoveries and story progression into one polished mystery adventure.

BLIND OPERA Your music becomes the ride. Blind Opera is a music-driven experience that transforms your own compatible audio files into neon worlds built around the music. Choose a song and Blind Opera analyzes it before you play, using its rhythm, energy, melody and musical structure to shape the journey ahead. The track twists, climbs and turns with the music while glowing scenery, tunnels, targets and world events surround you. Change the song and you change the ride. IMPORTANT: PLEASE READ BEFORE PURCHASING Blind Opera cannot use songs from an Apple Music subscription, including songs downloaded to your device for offline listening. Blind Opera needs access to the underlying audio data of a song so it can analyze the entire track and build the experience around it. Apple Music subscription downloads are DRM-protected, and Apple does not provide third-party apps access to the audio data Blind Opera requires for this analysis. Downloading an Apple Music subscription song to your device does not make it compatible with Blind Opera. Blind Opera is designed to work with compatible, unprotected audio files that you own and can access through Files. EVERY SONG BUILDS A DIFFERENT WORLD Blind Opera doesn’t simply play a prerecorded level alongside your music. Your song influences the experience itself. Its musical characteristics help determine the movement of the course and the world that forms around you, creating a different journey for different music. A quiet passage can feel completely different from an explosive one. Change genres, change songs, or choose something unexpected and see where the music takes you. THREE WAYS TO EXPERIENCE YOUR MUSIC NORMAL The core Blind Opera experience. Ride through a world generated around your chosen song, navigate the course, hit targets and chase a high score. VARIANT Experience your music through an alternate interpretation with its own visual identity. REWIND Turn the experience inside out with a reversed journey and inverted visual world. A WORLD THAT WAKES UP WITH THE MUSIC Race through glowing tunnels, sweeping curves and strange geometric landscapes. Encounter dynamic scenery and events as the world builds itself around your journey. No two songs have exactly the same musical fingerprint, and Blind Opera uses those differences to make each ride its own. BUILT FOR HEADPHONES Blind Opera is as much about listening as watching. Put on your headphones, choose a compatible song you know by heart, and experience it from a completely different perspective. BLIND OPERA Choose a song. Follow the music. Ride the unknown.

Blind Opera's advantage is rating (5.0 vs 4.3) and in-app purchases (none vs 10). On update cadence, device support and iOS requirement there is nothing between them.
