What makes a good hackathon challenge?

A successful hackathon challenge is defined by key features that drive participant engagement, creativity, and competition.

Relevance


A challenge should be related to a specific topic and is appealing when it addresses a current problem. It is more exciting to develop an approach that can have a positive impact.

Challenge


The challenge itself can often be quite challenging. It can be difficult to push participants to use their full skillset. There should be ample room for innovation and advanced solutions to encourage the development of new technologies and ideas.

Goals


The challenge must set clear objectives to ensure participants understand expectations and can be effectively guided towards success. Clarity in goals is essential for a productive hackathon experience.

Openness


While there are goals and rules, a good hackathon challenge should leave enough room for creativity. It's important to encourage diverse approaches and solutions. This allows participants to harness their skills and ideas and develop solutions that embrace various perspectives and use cases.

According to our terms, your participation in BaselHack is entirely voluntary. Everything you create – be it ideas, solutions, code, or prototypes – remains the property of you and your team. BaselHack does not claim any ownership or exclusive rights to your intellectual property. TL;DR: It all belongs to you and your team!
Absolutely! During the team-building session on Friday evening, simply sign up together as a team. If possible, please bookmark your preferred challenge in advance (or register your own) – see the FAQs below for more details.
To pitch a challenge, you’ll first need an account on baselhack.ch, register your own account here: https://www.baselhack.ch/user/register. Once registered, visit https://baselhack.ch/challenges/create-challenge and fill out the required information. You’ll need a challenge title, a short description (summarizing your challenge in one sentence), and a longer description to explain it in detail. After a brief review, we’ll publish it on the website. Don’t worry – we only check for appropriateness (e.g., no racism, no pornographic content), not for typos 🙂. If you have any questions or issues regarding challenges, feel free to contact one of the BaselHack teammembers on our Discord Server.
If you see an interesting challenge of the already published challenges on https://www.baselhack.ch/challenges, you can bookmark it in advance. This helps us get an idea of how many teams are likely to form around each challenge, thanks in advance! Just before Friday (official start and team-building day), we’ll assign a certain number of teams to each challenge. You can then simply join one of the assigned teams. We love seeing new friendships form! ;D
