Hack&Roll blobby celebrating


This hackathon is free of charge!
Just register (or you will not get food or swag) and come down!

Hack&Roll blobby busy working


  • Build something new. You may reuse code for specific components, but recycling an entire project is not okay.
  • Projects will be judged on awesomeness. Decisions made by the judges are final.
  • Hardware projects are welcome! We will also be having a booth that allows you to borrow some commonly used hardware for your projects.
Hack&Roll blobby thinking


This hackathon is open to:

  • Students in any educational institution, anywhere from primary school to graduate studies
  • Anyone awaiting entry into an educational institution (including NSFs and PhD candidates)

Students studying in overseas institutions are welcome, but we cannot provide assistance (e.g. visa, accommodation) in getting to Singapore.
Non-students are welcome but will not be eligible for prizes.
