The Google Nexus Twitter account will post a puzzle in just a few minutes, at 12EST. If you're the first to person to figure out and Tweet the answer back at them, they'll give you a free Nexus S. And at their event yesterday there was some talk of giving away Chrome netbooks to puzzle winners, too, so if you keep your eyes peeled and sleuth your hardest you might just win one of those, too.
Google says they'll be putting up a new puzzle every day—yesterday's answer was CREAMPUFF. I'm just going to tweet DONUTHOLES back at them as soon as the new puzzle goes up, because, hey, they're clearly into treats, and because I'm really hungry. [Google Nexus]
