For graphic designers, nothing simultaneously holds more power and intrigue than the pen tool.

Pressing its keyboard shortcut, the “p” key give some the keys to the kingdom and makes others break out in a cold sweat. Mastery of the pen tool and its bézier (pronounced “BEZ-ee-yay”) curves open a whole world of possibilities to designers. The thing that makes the pen tool so powerful is that its resultant designs aren’t affected by resolution. They can be scaled from ultra-tiny to something the size of a football field with none of the pesky pixellation you’d get when scaling, say, a photo of your cat.

But the pen tool can be hard, man.

And that’s why this game is so dang cool. I’ve been playing it for a couple minutes and already learned something new and awesome. I had no idea the “alt” key could “break” the handles of a curve while I was dragging it out.

If you’ve struggled with the pen tool in the past, spend some time playing The Bézier Game. You’ll be an expert in no time.
