THANK YOU FOR PLAYING MARBLIE!

Marblie is a playful physics sandbox.

Whether you're designing elaborate courses, tinkering with gravity, or just watching marbles swirl down a funnel for the hundredth time, this simulator is meant to spark joy and curiosity.

Build, test, and watch marbles race through your own custom tracks. It’s a toy, all about creativity.

This project started as a fun experiment — a mix of physics and design. Now a toy for anyone who loves rolling things down ramps and seeing what happens.

Built by Younghoo Nam, powered by Three.js and Rapier. If you liked this project, check out my other projects at my portfolio!
