Top Trumps 3D Augmented Reality card game. As a supporting element to their decks of cards, Top Trumps introduced a series of special packs with augmented reality markers printed on the cards, providing a new interactive experience. Upon installing the software and showing the initial card to the webcam, the user is asked a series of questions, the answers for which are other cards in the deck. Upon completing the questions a special stage is reached.
In the transformers pack, this allowed the user take control of Optimus Prime and drive him around the table, and launch rockets.
