Bell Circuit
Bounce sound. Ring every bell.
Every board is a small machine for making sound. A pulse leaves the emitter and travels — one cell, one beat — splitting at forks, bending off mirrors, waiting at doors. Wherever it reaches a bell, the bell rings. A music puzzle you solve by ear as much as by eye.
Bell Circuit is in final tuning. It's headed to Google Play and the App Store — check back here, or get in touch to hear when it lands.
Why it feels different
🎼The board is always playing
No play button. The pulses are already moving when the level opens — move a piece and your edit lands on the next bar line. You're not running experiments; you're conducting.
🔔Solve it and you hear it
The moment the last piece is right, the chord lands. That's the reward — not a score popup, the sound itself.
🧠A puzzle, not a rhythm game
Nothing is timed, nothing needs fast fingers. No combo meter, no failure state, no clock.
🔇Made of sound, not recordings
Every note is generated on your device as it plays. No audio files, no microphone, no permissions at all — and it plays fully offline.
♟️Thirteen boards, one answer each
Every level is proved by an exhaustive solver to have precisely one solution. No guesswork, no padding.
🎹Height is pitch
A pulse climbing the grid is a rising melody you can follow with your ear.
