What is a hackathon?

A hackathon is a type of technical competition! Attendees work with new people on cool ideas and get the resources needed to bring them to life. We do not condone, nor allow, any hacking or illegal activities! DeltaHacks 13 is an official MLH event. The MLH code of conduct can be found here: http://mlh.io/code-of-conduct

Who can participate?

Anyone who is willing to learn and have fun! If you have an idea - or even if you don't, you're invited! All university and high school students over 13 during the date of the event are welcome at DeltaHacks!

How much does it cost?

Absolutely nothing! All you need is a personal computer to bring along with you to the event!

Will attendees still get awesome swag?

Yes! There will be awesome swag for participants, mentors, and sponsors.

What do I need to participate?

DeltaHacks 13 will be in person. Bring in your laptop, reusable water bottle, and prepare to build some amazing projects!

When will hacker applications be released?

Hacker applications will be released closer to the event. Follow us on socials to stay up to date and find out as soon as applications open.

Do I have to have a team going into the event?

Nope! If you do, great! If not, there will be opportunities to network before and during the event to find some other hackers to build a project with.

How are projects judged?

Projects are judged by event sponsors and experts from the tech sector. Projects are presented to judges at the exposition and evaluated on multiple factors such as presentation, creativity, practical application, and originality.

What is DeltaHacks?

The word “delta Δ” means change, which inspired the name DeltaHacks - McMaster's annual Hackathon for Change. This year, DeltaHacks will host hundreds of participants in January 2027. We aim to inspire students to hack for positive change in areas like the environment, health, inequality, education, and more!

I'm new to hackathons, what should I do?

We love first time hackers! We will be providing mentors during the hackathon and running workshops, so you're welcome no matter your skill or experience level.

Will DeltaHacks 13 be in person or virtual?

DeltaHacks 13 will be taking place fully in person this year.

What's the event schedule like?

We'll be putting up one closer to the event, you can expect a lot of talks and presentations, fun events, and a lot of chances to meet new people and win prizes!

Will hardware be provided?

Yes, we will have hardware available provided by MLH! Feel free to bring your own hardware if you have the material to include into your hack.

How big can a team be?

Hackers may form teams of up to 4 people. There are no restrictions for who they can be, so you can team up with hackers from any school, country, or experience level. Teams can be formed before or during the event at hackers' own discretion.

What am I allowed to hack?

Your hack can be absolutely anything! There will be certain challenges your team can work towards, and you can win amazing prizes (to be released later) if your submission wins the category!
