Many fields of Economics, Management, Finance or Entrepreneurship study decisions involving interdependencies between decision-makers, and make predictions on how these interactions such unfold, or how they should vary with a changing economic environment.In such a context, the idea of Gamification is to provide lecturers and students with a simple, powerful and customizable digital tool that in a playful manner brings such interactions to the classroom. The main tool is based on Otree, an open source and Python-based software, originally aimed at conduction economic experiments for research purpose. This tool allows, in general, to create an easily accessible online environment for studying certain strategic situations, where students can participate instantaneously using their table, PC or Smartphone.
