Google is offering members of its Local Guides program a chance to win a custom Nexus Live Case just for leaving high-quality reviews on Google Maps. Open to Local Guides in the U.S., all you'll have to do is write as many high-quality reviews as you can through June 29 and you'll have a shot at winning.

You could win a Nexus Live Case for reviewing places on Google Maps

From Google:

Review places you've visited anywhere in the world for a chance to win a custom Live Case for your Nexus device. Each review you write is a new entry in the contest and the ten Local Guides who write the most high-quality reviews on Google Maps win. Winners will receive a code to redeem the custom Live Case of their choice.

In case you're unfamiliar, the Local Guides program is what Google calls a "global community of explorers sharing their discoveries on Google Maps." Participants are encouraged to leave high-quality reviews for local restaurants, museums, and other points of interest around them in Google Maps.

If you're interested, you can sign up to be a local guide and participate in the contest. Google says that the ten winners will be announced on July 7.
