Recreate line patterns by moving connected dots into the correct positions. Each level presents a target design and a set of connected points on a grid. Drag the dots to change the arrangement of the lines, then compare your result with the pattern shown above the board. Finding the solution requires careful observation and an understanding of how each movement affects the complete shape. The puzzles begin with straightforward arrangements before introducing more detailed designs that require additional planning. If a move does not work as expected, use the undo or reset controls to try a different approach. Hints are also available when you need some guidance. Features: • Move connected dots across a grid • Recreate the target shown in each level • Solve a sequence of spatial pattern puzzles • Undo individual moves or reset the board • Use hints when you need assistance • Progress through increasingly detailed arrangements • Play with simple drag controls Examine the connections, consider each position, and discover how to form every pattern.

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.
