Season 1 · Charge the City
Secondary-school students, and Preparatory Year and first-year university students, compete in separate competitions held at the same venue.
How a competition runs
Your school or university registers you and gives each team or student a player ID.
Practise in the Arena and try to beat the two bosses.
Hand in your final file on the My team page before the deadline. After that, nobody changes their code.
Every file runs on new test days nobody has seen. The official ranking is published, and each team reads its coach report on the My team page.
The top entries meet at the venue, played live in 3D.
Questions
The Schools Competition is for secondary-school students aged 15–18 (Grades 10–12 or equivalent, any curriculum). The University Competition is for Preparatory Year and first-year students in any subject, from engineering and computer science to business.
In the Schools Competition, yes: teams of up to 3 students submit one file together, and a school may enter more than one team. In the University Competition every student enters on their own.
No. Entry is free for schools, universities and students.
A laptop or a school computer with a modern browser, and basic Python. The Arena runs in the browser, so nothing is installed.
Students practise in the Arena, then hand in one Python file on the My team page before the deadline, using the player ID and team code their school receives. Every file runs on the same new test days that nobody has seen, and the best entries meet at the Grand Final.
Out of 100: up to 80 for getting people where they need to go on time, 10 for leaving cars charged for their next trip, and 10 for using as little grid energy as possible. How to play explains each part.
Practice runs stay in the student's own browser. Official files are used only to run and check the competition.
In December 2026, for both competitions. Register interest and we will tell you first.
