Google's hosting some kind of contest on their Google Nexus S Twitter page.
Puzzles are as follows [will probably update as they are released]:
Puzzle 1: 3154, 75757, 854, 2737, 37553, 15059, 6278, 4085, 3634, 2414, 46483
I'm personally ineligible to win (not a legal resident of the UK, and I am currently not physically present in the Philippines), but hey, Google's usually good at making puzzles. Anyone else want to take a crack at it? Chance of a free smartphone.
