An event where developers, designers, project managers, and others come together to build software in a short period. Participation requirements and methods vary by hackathon. Ideas are pre-determined, products are developed, and rankings are announced based on fair evaluation. Form a team and aim high at hackathons!

On CraftStadium, both hackathon participants and judges are called 'Players'. Players form teams of 2-5 people to take on hackathons. Role division and effective collaboration within the team are key to success. Players can improve their development skills and deepen connections through hackathon participation and judging. Players who achieve excellent results receive generous prizes and exclusive items.
