Is food provided at the event?

Lunch, dinner, and a few light snacks are provided at the venue, but you are also free to order food there to your preference. We recommend that you eat breakfast before you arrive since it will be a long day.

Do you need experience?

This competition is specifically targeted as a "learnathon." While experience does help, our mentors will guide you from start to finish in making a project that you want to make with your group.

What if you're not a programmer?

Programming is a skill that anyone can pick up; we have the best mentors to be able to facilitate your learning. That said, skills like graphic design, sound design, and expertise in any other subject can be just as valuable as programming to your group.

Are there any awards for projects?

Yes! While this is not aimed to be a competitive hackathon, awards along with various prizes, worth over 2000$, are availble to the best and most creative projects. There will be one grand prize and a few surprise sub-prizes, but one project will only be able to one award.

How do I pay?

Please bank transfer the cost to 218-910336-76507 하나은행 강예준.

When are the deadlines?

3/7 is the deadline for early registration and 3/14 is the deadline for regular registration.

Can I be a mentor?

Help is always appreciated :D. Please drop us an email at if you are interested in joining and gifting the community your skills and time.

How much does the event cost?

The event costs 25,000krw for early registration and 30,000krw for regular registration.

What programming language?

It will be up to each individual team to choose a language that they or their mentor is familiar with. However, the default recommendation is making a web app using javascript. All competitors will be recommended to use as their IDE and must strictly comply with any licensing and copyright requirements.
