It's not all that complicated - you just need the right browser. I couldn't get it to work in IE or Firefox, but the game worked okay in Chrome.
The sweepstakes ends April 21, and you get one entry.
They show one location for each of 52 weeks, and you have to pick just one location to try for. Then using their clues and google maps, figure out where that location is. They have a little pin thingy you put on the right map location -- except mine kept sliding off to areas I didn't want. Took me forever to get it pinned to the right location.
Anyway, the catch is, if you win one of the 52 weeks, then you have to go to that location in that specific week, otherwise you forfeit.
I couldn't get the rules to copy, but basically each trip package include: Economy Class air travel for winner and guest on Delta Air Lines from airport closest to the winner's residence to LAX Airport.
Two round trip airline tickets for winner and guest from LAX airport to Sydney, Australia on Virgin Australia.
Two round trip airline tickets for winner and guest from Sydney to the week's Experience on Virgin Australia if needed.
Seven night hotel accommodations in hotels determined by the Sponsor in the Experience location week that was won.
Clear?
