Wherigo is an icon type in geocaching A traditional cache must be at the given location… A multi- cache is found having first visited another location… A letterbox hybrid has a stamp inside it… A Wherigo cache is found once you’ve played a little game on your phone. This game can be a tour guide of a location, a fun interactive game, a count-down from where you are to a final location… (whatever it is, PLEASE don’t play on your GPS – it *really* doesn’t work as well)
