This is the unofficial archive of Google Code Jam, Kick Start and Hash Code competitions held by Google in 2003–2022 and discontinued in 2023.
All available data was downloaded from the official website in early March 2023 (and updated in late May 2023).
This includes scoreboards, problem statements, editorials and test data.
For some of the competitions (most of 2008–2009, GCJ 2018 and all of 2019–2023), all source code submitted during the contests is also available.
Per Google’s Coding Competitions Terms, all code is published under the MIT License.
For 2008–2017, data from go-hero.net was used for solution metadata (language and size);
it might be sometimes missing or inaccurate as the submitted code was not being validated by the server at the time.
Before 2008, competitions were based on the TopCoder platform, that data is unavailable.
Where possible, contestants were automatically matched with their Codeforces profiles, with some manual fixes done for the final rounds according to the data from Codeforces community.
The displayed color reflects their highest ever attained rank as of 2023-06-01, not the actual rank at the contest date.
For 2008–2009, previously archived data with TopCoder usernames was used instead.
Click on any username in the scoreboards to see their whole competition history, or search by name.
Downloadable zip archives for each year are also provided, in case this website goes down.
Solutions and raw Google API data are included in the zips in SQLite Archive format.
User profiles and backend scripts for serving files from SQLite archives are packaged here (139 MB)
In case of any suggestions, you can contact me via my Codeforces profile.
