## What is Brownian Game?

Can you outsmart Brownian motion? Dozens of collisions, one steel ball. From simple bounces to colorful chaos—physics has never been this addictive.
Brownian is a minimalist physics puzzle indie game that puts you in control of a steel ball inside a tube filled with colorful particles, just with one click. Your mission? Change every particle to the same color through calculated collisions.

SIMPLE TO LEARN, IMPOSSIBLE TO MASTER
• Tap and drag to release your steel ball
• Watch as realistic physics creates chain reactions
• Time your moves to beat the clock

PURE PHYSICS GAMEPLAY
• Brownian motion simulation
• Elastic collision mechanics
• Gravity-based challenges that test your precision

105 LEVELS OF ESCALATING CHALLENGE
• Start with 2 colors, progress to 8
• Earn up to 3 stars per level
• Unlock new challenges and soundtracks as you master the basics

MINIMALIST PERFECTION
• Clean and minimalist design
• Designed for one-handed play
• One-tap game mechanic
• Relaxing soundtrack

Every tap matters. Every collision counts. Can you master the simplicity of such complexity?
