This study explores the DigiEduHack project - an international initiative designed to transform digital education through Educational Technology (EdTech) hackathons. The aim of the study is to provide an in-depth analysis of the project's objectives, methodologies, and results, demonstrating the benefits of using EdTech hackathons as a dynamic learning format in life-long learning education. The paper will also highlight some of the lessons learned from the DigiEduHack initiative that will allow to increase the impact of the hackathon as an education instrument.

The research methodology used in the current study is primarily qualitative, including the analysis of data collected from various DigiEduHack events, related social media posts and articles.

The DigiEduHack project has proven successful fostering innovation in digital education. Some of the key results include:
1. Enhanced Learning Experiences: Participants have reported improved understanding of and acquired new skills related to digital technologies and their applications in education.
2. Best Practices and Lessons Learned: The project has identified and disseminated best practices of organizing effective EdTech hackathons and identified some areas for possible further improvements. One of the most significant lessons has been the importance of including in the format EdTech companies as well as policymakers. The involvement of EdTech companies and policymakers is crucial in bridging the gap between academic theory and practical application. Their participation provides valuable insights, resources, and real-world perspectives, enhancing the overall quality and relevance of the hackathons.
3. International Collaboration: By connecting local hackathons to a broader, international platform, DigiEduHack has increased the appeal and impact of these events, encouraging cross-border collaboration and knowledge exchange.

Hackathons have also been described as a challenge-based learning format that promotes creativity, critical thinking, and practical problem-solving. The findings of the study have allowed formulating actionable guidelines for organizing high-impact hackathons that offer participants a rich learning experience.

One of the limitations identified in the current practice organizing hackathons is their prevailing local nature that limits their visibility and impact. DigiEduHack addresses this by promoting international collaboration and the dissemination of best practices. This does not only increase participation in the events but also ensures that the developed innovative ideas have a broader reach and impact.

The DigiEduHack project demonstrates the transformative potential of EdTech hackathons in digital education. These events serve as catalysts for innovation, providing a platform for students, educators, and innovators to collaborate on solving real-world educational challenges, allowing, among the others, in-service teachers to participate in creating break-through level educational technology products and services. The challenge-based learning format of hackathons aligns well with the educational goals of developing critical thinking, creativity, and problem-solving skills. Hackathons can be used as an educational method or integrated into academy-industry knowledge transfer programs, allowing educational institutions further capitalizing on their benefits.
