HP is giving away a number of its Slate 7 tablets, but not without a good old treasure hunt first.
With the help of Twitter and Google Maps, loot hunters can use the clues on offer to track down one of five prizes starting at an approximate location each day from August 5th to 16th.
Using a microsite and Google's mapping service, participants use their mobiles to scour one of the four cities
Four cities will be included in the challenge, with London's hunt on the 5th and 7th, Manchester the 8th - 9th, Birmingham offering up prizes 12th - 14th and finally Glasgow on the 15th to the 16th.
All there is left to do then is be there first to the gold. Or HP Slate 7 tablet as it is in this case.
To enter, all you have to do is visit the HP UK Facebook page, download the free app, and tweet and much as is tweetingly possible with the hash tag #HPSlate7.
