// ABOUT THE GAME

What it is.

A physics puzzle where one perfect shot triggers everything.

Aim. Release. Watch the chain reaction unfold. Each level is a tightly designed system of bouncing physics — your job is to find the one ball that contaminates all the others.

Equal parts billiards, pool and chemistry. Equal parts satisfying when it works, and infuriating when you almost have it. We promise: it always works eventually.

// 01
Real physics
Every collision is calculated. No tricks, no luck — just trajectory.
// 02
One-shot levels
Each puzzle is a single shot. No second chances. Just retries.
// 03
Chain reaction satisfaction
When the last ball turns — chef's kiss.
// 04
Hand-tuned levels
Every layout designed by hand for a specific 'aha' moment.
