About this game

Bell Circuit is a music puzzle game you solve by ear as much as by eye.

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.

The goal never changes: make every gold bell ring TOGETHER, on a bar line.

That is the whole rule. You are never told a different target next level, never asked to memorise a sequence, never handed a new objective to decode. One rule, learned once. What changes is the machine — arms of unequal length, doors that open on one beat in four, rooms that hold a pulse and let it go bars later, voids that swallow it and hand it out across the board, crossings where two pulses meeting cancel each other, amps that throw one two cells in a single beat, and branches you must silence before they wake a bell that should stay quiet.

THE BOARD IS ALWAYS PLAYING
There is no play button and nothing to press to test an idea. The pulses are already moving when the level opens, and it sounds wrong — audibly, immediately, in a way you can hear the shape of. Move a piece and your edit lands on the next bar line, so the music never stops and never stutters. You are not running experiments. You are conducting.

SOLVE IT AND YOU HEAR IT
The moment the last piece is right, the board cuts to the answer and the chord lands. That is the reward — not a score popup, the sound itself.

A SOUND PUZZLE, NOT A RHYTHM GAME
Nothing is timed and nothing needs fast fingers. There is no combo meter, no failure state and no clock. It is a logic puzzle whose feedback happens to be music, so you can think about it for as long as you like while the board plays underneath you.

MADE OF SOUND, NOT RECORDINGS
Every note is generated on your device as it plays. The game ships with no audio files at all and never uses your microphone — it asks for no permissions whatsoever. Height on the board is pitch, so a pulse climbing the grid is a rising melody you can follow with your ear.

PLAYS OFFLINE
No account, no sign-in, no servers. Nothing about a Bell Circuit puzzle needs a connection.

THIRTY-EIGHT BOARDS, EACH WITH EXACTLY ONE ANSWER
Every level has been proved by an exhaustive solver to have precisely one solution. No board is guesswork, none has a lucky second answer, and none is padding. Six chapters, each with its own sound and its own machinery: first light, cross currents, an echo hall in the relative minor, a void, an interference field, and the full circuit.

Headphones are worth it.
