Serious games and playful learning are increasingly in demand in the education sector. This is not surprising, as all people engage in play in various ways from birth. We now know that play is one of the most effective forms of learning. Collaborative digital gamebooks allow educators to respond to this demand without needing external game designers and software developers. They can creatively, didactically, and technically prepare their own areas of knowledge independently, with the gameplay limited only by their own ideas and not by technical constraints. A collaborative gamebook is a digital interactive game where text components create a mental image in the player's mind throughout the entire game environment.
