Here is a video explaining the rules a bit more, but spoiler alert: don't go past 2:37 unless you want to see how it's done.

It’s never been easier to be a filmmaker, providing you have the technique. Enter the Film & Cinematography Mastery Bundle, an online boot […]
Breaking into the indie video game market may be easier than you think. It all starts with an idea, and then it’s a matter of finding the right development platform to bring it to life. No matter what that platform is, it’s a good bet that it’s covered in the 2019 Game Dev & Design […]
Learning a new language like Spanish doesn’t have to be hard. Either you can buy a ticket to a Spanish-speaking country, immerse yourself in the culture and pick it up intuitively – or you can do it from the comfort of the chair you’re in right now by logging on to Rocket Spanish. There are […]
