Line Rider

About this site

Draw tracks and watch a little rider sled down them under real physics. Build loops, jumps and absurd ramps; the community makes entire choreographed music videos with it.

When to open it

Set aside a while: this one easily runs past 15 minutes. It's best on a computer with a mouse or keyboard, and it's silent, so it's safe at work or in class. Best for tinkering and builders.
