Google Code Jam Statistics

Revision en8, by vstrimaitis, 2019-05-13 13:51:18


As you probably know, there are some great websites for examining various statistics about past Google Code Jam rounds (e.g. or However, the last rounds these sites have are from the year 2017. I don't know for sure, but this might have something to do with the fact, that in 2018 Google launched their new Code Jam system and probably changed their APIs as well.

Long story short, I spent some time reverse-engineering the APIs and created a simple script to retrieve some data about various Google Code Jam rounds using the new API, as well as a simple website for viewing some statistics of round from 2018 and up. You can find the website here:

Here are some features which are currently supported:

  • Some numerical stats (number of participants, number of perfect scores, etc.)
  • Some charts (Top countries by number of participants / average score / most top-scorers, score distribution)
  • Full scoreboard
  • Ability to filter by country

The website is still in its early development stages and supports only some basic stats. If you have any suggestions of what else could be added to the site, don't hesitate to share, or (even better) submit a pull request! The code can be found at
