Pebble
Choir

A physics merge game where every collision makes music

Pebble Choir is a free browser physics game in the family of Suika and merge games, but quieter. You drop pebbles into a vessel — when two pebbles of the same size touch, they merge into the next larger voice, and every collision plays a note. The challenge is spatial: the vessel is a fixed size, and if pebbles pile up past the rim, the choir falls silent. There are eight voices to grow through, from the smallest Hush to the final Choir. There is no account, no ad, and no streak. One run, one quiet performance.

How to play

• Tap anywhere inside the vessel to drop the next pebble.
• Two pebbles of the same size merge on contact, growing into the next voice.
• Every merge plays a note — longer chains make longer musical phrases.
• Keep the rim clear. If pebbles pile up past the top, the run ends.

How to play

1. Tap anywhere inside the vessel to drop the next pebble.
2. Two pebbles of the same size merge on contact, growing into the next voice.
3. Every merge plays a note — longer chains make longer musical phrases.
4. Grow pebbles from the smallest Hush up to the final Choir.
5. Keep the rim clear — if pebbles pile past the top, the run ends.

Tips

• Drop near the center so pebbles settle evenly across the vessel.
• Aim same-size pebbles at each other to trigger merges on contact.
• Don't fill the rim early — leave room for the next size up to land.
• Listen for the chord: a long chain means a good move just happened.
• The vessel is fixed, so plan two drops ahead before you release.

Every collision makes music — Pebble Choir is a merge game with a musical payoff, not just a score. No precision aiming is required; pebbles tumble naturally. There are no ads, no account, and no streak. One quiet performance per run, in a single browser tab. Bilingual (English and 简体中文).
