## What is Chain Reaction?

One clever move. One glorious machine.

Chain Reaction is a hand-crafted physics puzzle game about building the missing piece of an elaborate chain-reaction machine — then pressing GO and watching everything you set in motion ripple across a miniature workshop.

Drop a ramp in the right spot and a steel ball rolls, dominoes topple, a trapdoor swings, a catapult fires and a bell rings on the far side of the bench. Get it wrong and you'll see exactly where the chain broke — tweak, retry, and try again in seconds.

EIGHT WORKSHOP WORLDS
• The Workbench — ramps, planks, levers and domino runs
• Clockwork House — pendulums, gears, pulleys and hammers
• Toy Lab — springs, fans, balloons, catapults and explosive confetti poppers
• Flowworks — tanks, valves, pipes, water wheels and floats
• Magnetron — magnets, polarity and electromagnets
• Spark City — batteries, wires, motors, relays and lights
• Elemental Engine — flames, steam, wax, ice and melting
• Quantum Workshop — portals, gravity fields and energy beams

256 HAND-BUILT PUZZLES
Every level is designed by hand and verified solvable, with a real solution, a fair challenge and three stars to earn: finish the machine, use as few parts as possible, and master a bonus goal.

A NEW MACHINE EVERY DAY
Daily Machines and a Weekly Challenge are generated fresh and verified solvable — come back and beat your best score.

YOUR OWN WORKSHOP
Unlock over 100 parts, collect blueprints, decorate your workshop with trophies, finishes and ball trails, and build anything you like in the Sandbox.

FAIR AND FRIENDLY
• Play offline, any time
• Hints when you want them — never required

• Optional rewarded videos; a one-time purchase removes ads
