Microsoft's Puzzling Sweepstakes

Microsoft has kicked off the latest of its Pandora's Box demo promotions with a new contest, the grand prize of which is an eight-day, seven-night trip for two to one of the seven cities featured in the full version of the game. Possible cities include Honolulu, Hawaii; London, UK; Nairobi, Kenya; Santa Fe, NM; Shanghai, China; Vancouver, British Columbia; and Athens, Greece.

All you need to do is register on the Pandora's Box site. You must be over the age of 18 to enter. Good luck.
