Modern children use more and more Internet services for various purposes - entertainment, learning, communication with friends, etc. One of the tasks of parents and educational institutions is to inform the children about the rules for safe usage of Internet services and train them to follow these rules. In this article we present a set of mini games aimed at the formation of digital competencies on the topic of “Safe Internet”. The games are designed for pupils in low secondary schools. They are developed as SCORM packages and are delivered to students in Moodle e-learning environment. In addition, we present the results of their pilot testing with students in 5^th, 6^th, and 7th grades.
