Mathematics is an area of study that particularly lacks student enthusiasm. Nevertheless, with the help of educational games, any phobias concerning mathematics can be considerably decreased and mathematics can become more appealing. In this study, an educational game addressing mathematics was designed, developed and evaluated by a sample of 33 students of the fifth grade of a primary school. Each student played the educational game "Playing with Numbers" (PwN), performing additions with integers, additions with decimals and multiplications with integers for a total of one hour, divided into four sessions. Next, the sample was asked to provide feedback regarding specific questions, and the analysis of the results showed that the PwN application is attractive and delivers usage. The attraction of the PwN game probably owes its success to its competitive element, as users are driven to achieve high scores. The PwN application was also found to be easy to use, and this made the challenge of achieving a high score more appealing, as success depended only on the cognitive skills of the user and not on any weaknesses or difficulties raised by the application itself. The findings of this study show that students would benefit from educational games and would be happy to work within an environment that motivated them and indirectly forced them to deal with mathematical operations while playing.
