The topic of this final paper is focused on the behaviour of consumers, more precisely the players of lottery games in the newly formed pandemic that, starting in 2019, hit the whole world. As a result od the pandemic, consumer behaviour has been forced to change due to changes in the way services are provided and changes in the way consumers can make purchases. In the Republic of Croatia, since the beginning of the pandemic, there have been several „closures“ of certain business branches, as well as a „lockdown 2“ that lasted several months and significantly affected the habits of most consumers. In order to better monitor consumer behavior in a pandemic, we must first understand consumer behavior by nature, so the paper will explain the theory of consumers and their behavior, after which such a theory will be compared with consumer behavior in a pandemic established by conducting an anonymous survey in Zagreb and Zagreb County. Based on the obtained data, it will be possible to give a proposal to the management of the Croatian Lottery on how to improve and achieve the highest quality and most efficient business during the pandemic in order to increase the satisfaction of its customers. In the end, the conclusion of the paper will be given. 2 Temporary condition set by the governing body requiring people to stay in their homes and to retain from or restrict activities outside of their home that involve social contact (eg. dinner at a restaurant or large social gatherings)
