This is not your typical hackathon.
hillsHacks was born with a mission: to show that computer science is something anyone can learn. It's more than memorizing technical jargon and stuffing code into machines. CS is for innovators, creators, problem solvers, artists, and you.
Rather than leave you alone expecting a full-fledged product launch at the end of the day, we'll guide you through the learning process with workshops from Watchung Hills alumni. Plus, we'll provide you one-on-one mentorship and an opportunity to listen in and ask questions about tech during our Panel Q&A session. Deviating from the traditional hackathon, there will be a no-code design challenge, with a greater emphasis on ideas and how technology can be used for good. Participants can win generous cash prizes, too!
This is the ninth iteration of hillsHacks, Watchung Hills' premier hackathon open to students grades 7 through 12.

FAQ
Can you spend a day without using some form of technology developed in the last 5 years? It would probably be difficult — technology has completely changed the way we live our lives. Regardless of your experience, you will learn something new at hillsHacks about how computer science is being used all around us — often in things we take for granted! All students in grades 7 and up are welcome.

What if I don’t know anything about coding or computer science?
No problem! We highly encourage beginners to come, and our workshops will give you opportunities to learn about fundamental CS concepts. After creating an idea as part of our design challenge, you'll be ready to implement it on your own after the event!
I’m an expert at coding. What do I get out of this event?
Check out our advanced workshops. We recommend that you actively engage in our Panel Q&A session and consider competing in the competitive programming event (this applies to beginners, too).
Although teams are allowed, we highly encourage you to work solo for the competitive programming challenge.
