That’s awesome to hear about Brazil! Funny enough, Korea actually had a very similar rule too. We had a small car called the "Matiz" (kinda similar in vibe to the Beetle), and if you spotted a gold-colored one, you got to punch your friend! Nobody really drives gold cars anymore and the Matiz was discontinued, so that rule naturally died out.
Thanks so much for playing! It’s super cool getting to learn about fun cultural quirks from around the world like this!
