Design Space Cards is a card deck for envisioning new design ideas. In our paper, we discuss how a physical card deck can be used to generate new game ideas by sampling a design space. The deck has been optimized to merge relevant game theory elements into a concise card deck with limited categories and clear descriptions.

In a small, controlled experiment involving groups of design students, it was shown that the deck does not increase ideation speed but is preferred by participants. It was also shown that the target audience, children, were able to use the card deck to develop dozens of new game ideas.

The deck was developed by TU Delft student Mihovil Karac, Mathieu Gielen and me.
