The Competition is open to any player that enters their finished city on the show off page of the ElectroCity website.

Players must supply their email address and daytime contact number at the time of entry to be eligible for the competition.

You don't need to register in the register section, that is just for teachers, to start a new game just go to the game tag

ahhh - that is such a cool game, and would be nice to win the camera - I made a cool city, and they rate them at the end and I got a good rating and everything, and then when I pushed save it didn't do anything, like it was frozen or something I lost my city, and I din't have a chance to put my details in yet
