The game theory is one of less known areas of exact mathematics, mingling with humanist sciences, with focus on the psychological aspect of the individual. Therefore, it is not only a useful tool in the hands of scientists, but also on fields that are more attractive to the lay public. However, it would be wrong to think that game theory is able to find a way to win at every conflict. When you are a part of the game and decide on the next steps, you need to take the choice of the others into account. However, when you think about their choices, it is necessary to count with that that they are thinking the same way. In the moment of coming up with own strategy reflecting the ideas of the other “players”, you need to know they are doing the same. And this goes on and on, as stated by Godin (2012). Simply said, according to Sawyer (2012), “the content of game theory is analysis of a very wide spectrum of decision influencing situations“.
