The paper deals with experimental game theory and data analysis. The research question is how different pools of players understand strategic situations, they never faced before. And how they progress in finding solutions in interactions (even competition) with others. We propose four “pick a number” games, all with similar-looking rules but different properties. These games were introduced (in the body of scientific popular lectures) to very different groups. In this paper we present data gathered during lectures and develop tool for exploratory analysis using R language. Finally, we discuss the findings and open questions.
