Do you want to win a 3DS? Do you own a car?

If you’re a seasoned veteran of the internet, then you may remember this Mario Kart street art done by a graffiti artist on some Portland bike lanes a few years back. Jumping on the bandwagon this year, so to speak, is Waze, a free social app that offers GPS navigation with turn-by-turn directions based on other users’ traffic reports.

This weekend, Waze is offering users a chance to win one of five Nintendo 3DS systems they’re giving away by organizing what can only be described as a vehicular scavenger hunt. Starting tonight and ending tomorrow evening, you can download Waze’s app on your phone and open it to find a road map scattered with mushrooms, gold coins, and stars. Follow the Mario symbol and it will lead you to the nearest Nintendo launch, where you can enter to win a 3DS. (And a bunch of other prizes, too!) If there’s no Nintendo launch near you, worry not – you can enter anyway! Check out Waze’s blog for the official contest rules.

Seems like a fun little way to celebrate one of the biggest launches in Nintendo’s history, no?

Plus, you know, free stuff. It’s win-win, really.
