During last several years were made many experiments with aims to test whether the hypothesis and conclusions of the game theory are close to the reality. The experiments, surprisingly show people act irrationally. The paper explains behavior in experiments and shows them as the rational behavior. The theory of contextual games is used.

Such behavior can be seen as rational one.
