Lego's latest offering, Life of George, challenges players to build different models and uses an iPhone to recognise their efforts.
Once complete, the building is scanned with an iPhone or iPod touch, which recognises the blocks and marks players for speed and accuracy.
Paal Smith-Meyer, head of new business at LEGO Group, said: "Life of George is a result of our desire to provide an innovative way for existing and new fans to play with Lego bricks and interact with the brand.
"We understand consumers' powerful connection to casual gaming, and we have seen how successfully the Lego brand can translate to a virtual experience, so we pursued development of a fun way to combine both physical and virtual play into one product."
The game also sees the launch of a new Lego brand - George. See his Facebook page here.
