Computational thinking (CT), as defined by Wing, involves mental processes for formulating problems executable by an information-processing agent. Introducing CT in early childhood supports not only cognitive skills like pattern recognition and algorithmic thinking, but also teamwork and communication. Given the widespread presence of video games in children's lives, this study proposed a tablet-based application using mini-games to teach CT skills in an engaging and educational manner. The app was tested through direct observation with children aged 5 and 6, who responded positively and interacted easily with the games. While most mini-games were well-received, two were identified as needing improvement due to their high cognitive demands. The children found it easy to interact with the application and enjoyed engaging in its activities.
