One perhaps for fans of geolocation games like Geocaching or Pokemon Go, Munzee have a new app out so now is a good time to try this "scavenger hunt" game where you scan physical QR codes or virtual tokens that encourage you to visit interesting places.
It's something I play every so often, particularly when I'm visiting a new area as it usually leads me to discover some interesting local places. There's a referral code in the image below. :)
