We develop the method for fast building the text-based online “adventure” games for medical education. The starting point is the set of proven algorithms for diagnostic and treatment. The algorithms may build accordingly to the principles of evidence-based medicine. We check the accuracy of the algorithms, make the diagrams according by ISO standard, formulate test questions for all for all steps of algorithms and prepare distractors for the questions. We discuss the possibilities of switching to graphical screens in the future iterations.
