In conjunction with the free afternoon newspaper mX, Nintendo Australia is giving away several copies of New Super Mario Bros. Wii. The catch: you only get the game if you can locate one of the giant gold coins Nintendo will be hiding in the central business districts of our three most populous cities.

Nintendo's official description of the competition:

"For the first time ever you can play with up to 4 friends together on one screen with New SUPER MARIO BROS. Wii!

"To celebrate Nintendo are hiding 4 giant gold coins throughout the CBD between Tuesday 2 - Friday 4 December (Melbourne, Sydney and Brisbane).

"Each day clues will appear in mX to help you find the coins - the first 10 people to find the coin will win New SUPER MARIO BROS.(TM) Wii and the next 10 people will win $50 cash! Look out for the MX newspaper during the week commencing Monday 3 December for the first set of clues and your chance to win big! New SUPER MARIO BROS.(TM) Wii."

We're pretty sure that next Monday is the 30th of November, not the 3rd of December; it would then follow that Tuesday will fall on the 1st of December, not the 2nd. Otherwise, the competition seems legit -- there are more details at the official Nintendo website.
