Tweet to Zoom on Google Maps

Nectar, a UK loyalty card scheme, has released a Google Maps based competition, the Nectar Daily Deal Hunt, to promote the launch of Nectar daily deals in the UK cities of Birmingham and Bristol.

The competition takes the form of a treasure hunt in which participants can find prizes using Google Maps and Street View. The cleverest part of the promotional campaign is that to zoom in on the prize locations on the competition Google Map participants have to share the promotion on Twitter or Facebook. The more participants Tweet the more likely they are to be the first to find the hidden prizes.
