Hack&Roll is an annual 24­-hour Hackathon organized by NUS Hackers.

Hack&Roll is NUS Hackers' annual 24-hour hackathon, and the largest student-run hackathon in Singapore. In the spirit of hacking, we celebrate not just the most useful products, but also reward projects that are "awesome but useless" and for factors such as sheer overall coolness.

This event is open only to:

  • Students of all levels in any educational institution in Singapore (yes, exchange students count as well!)
  • Anyone waiting entry into an educational institution - e.g. NSFs, PhD candidates, etc.


  • Build something new. You may reuse code for specific components, but recycling an entire project is not okay.
  • Projects will be judged based on creativity, technical accomplishment, polish, and usefulness, in that order. Decisions made by the judges are final.
  • Hardware projects are welcomed!
