4T2 are celebrating their first game to be advertised on TV.
The advert, promoting the Vauxhall Corsa, directs viewers to play the game online.
Hidden around the city are 12 other Corsas - some are easy to spot, others are very well hidden. To enter the prize draw you only need to find 5 - to be at the top of the scoreboard you might need all 12! When you find another Corsa, drive close to them and they will join you in finding the remaining cars.
