The purpose of this article is to show ways how to promote a regional museum as an attractive choice for families with children for their leisure time activities. The aim is to promote the mascot of the museum as an attractive and interactive guide. The article presents the principles of gamification for museum´s promotional activities, the combination of offline and online communication with audience, especially parents with children. The first part of the article is about target audience and their specifications. For the purpose of the project, we chose the audience of parents with children. Then we applied the chosen techniques, such as gamification, storytelling, and interaction, to create an abstract museum guide - the mascot of the museum, specifically Novohrad museum and gallery in Lučenec. This mascot then communicates with the youngest audience of the museum through offline/online channels.
