The apprehension of problem solving skills is accepted in the literature as a future-century skill that is thought to affect academic and life-sustaining success through the life of the individuals. How the power of these algorithms effects of the people’s skills individually in the field of technological problem solving remains a crucial research topic. Therefore, the research aims to examine the effects of algorithm-based educational computer games on students' perceptions of problem solving skills within the scope of the curriculum developed for the "Problem Solving and Programming" units of the Information Technologies and Software course of the 5th and 6th-grade secondary school students. The study group of the research consisted of a total of 131 secondary school students. The "Perception Scale for Problem Solving Skills for Secondary School Students" developed by Ekici and Balım (2013) was used as a data collection tool in the study. As a result of the research, it was seen that both the experimental and control groups had high perceptions of problem solving skills in terms of the main and sub-factors of the scale. After the application, it was found that there was no significant difference between the students' problem solving skills scale total perception and perception sub-factor scores within and between groups. It was determined that there was a significant difference in favor of the experimental group in the mean scores of the willingness stability perception factor both before and after the application.
