The winner Junction 2015 was Slush Smackdown, from the Supercell Unlimited track. The team created a game where the players program their own boxer who then competes against other players' codes in real-time. It also won the whole Slush Hacks -hackathon competition main prize, worth 20 000 EUR.

### Junction 2016

The teams had 48 hours to develop their ideas and afterwards demo them to other attendants and judges. The main prize for the winning idea of the 2016 event was 20 000 EUR, and many companies offered their own bounties for solving challenges in a specific way or using pre-specified technology. Teams were provided a number of different API's and other emerging technologies to develop their concepts including Oculus Rifts, HTC Vives, Apple Watches, 3D-printers, Microsoft Hololens, and Estimote Beacons among others.
The winner team was suju.online, who created a tool for event organizers and public transportation decision makers that allows them to design dynamic routing for the self-driving bus. The team originated from the local Aalto University and the hack was part of the Future of Mobility track.

### Junction 2017

Junction 2017 was held on November 24–26 in Dipoli, the main building of the Otaniemi campus of Aalto University. About 1500 participants from over 90 nationalities attended the hackathon. Partners included Spotify, Daimler, Smartly.io, European Space Agency, Microsoft and others.
As always, the teams had 48 hours to work on their projects, with the event ending on Sunday with a demo expo. This year, the winner of the 20 000 EUR main prize was appointed using a new judging process. An open source technology called Gavel was used first to determine the finalists from each track. Then, a panel of expert judges inspected each finalist in delicate detail, even going through the project's code repositories.
The main prize was won by team Glados. The team created Signvision, a tool for maintenance personnel to map out traffic signs that need to be repaired. The hack was part of the Big Data track.

The teams had 48 hours to work on their projects, with the event ending on Sunday with a demo expo. For 2018, the reviewing process for the main-prize winner was improved further to make it more transparent for the participants. Instead of a multi-level process that was unclear to participants, Junction 2018 used a peer reviewing system, where the participants themselves chose the main winner.
The winner project was Oneiro, created by the previous winning team Glados. Oneiro is an application that lets electric vehicle owners rent their EV chargers for others in need.
