Welcome to LyonHacks III, a 60-hour hackathon!

LyonHacks III will start on April 7th at noon (12:00PM) and will end on April 9th at 11:59PM.

A hackathon is a programming competition that challenges teams to design and pitch a software application to our panel of judges. During LyonHacks III, teams will create a code-based project that falls under one of the themes, to be released at the start of the competition period. The hackathon will also feature workshops and guest speakers to help build useful skills.

All Ontario high school students ages 14-18 are invited to compete, forming teams of up to 4 students. In addition, there will be many prizes to be won from our collaboration with Project Metropolis!
