Design Thinking (DT) methodology is an iterative process in which, through 5 stages, organizations try to creatively solve consumers problems through empathy, defining, ideation, prototyping, and testing, to reach the best possible solution. Research confirms that certain mindsets are associated with the success of this process. Mindset is a way of thinking, beliefs, and habits which define an individual or a group of people. The aim of this research was to determine any differences in mindsets between respondents in the mobile game industry based on their usage of design thinking methodology. The survey questionnaire method was used for the research itself. 96 respondents of every gender from Croatia who work in the mobile game industry participated in the survey. The results of the research showed that the majority of respondents, regardless of whether they use the DT methodology or not, possess mindsets important for the successful implementation of the DT methodology. It was also shown that the DT methodology is used to a large extent during innovative processes of business in the two surveyed companies. No big difference was found in mindsets of people who are familiar with the DT methodology and those who are not. Respondents believe that the DT methodology significantly contributes to the success of the company as well as to better productivity of the respondents, although sometimes they themselves are not aware that they are using it.
