The Dodgeball Tournament Returns!

The GitHub Charity Dodgeball tournament is back, and better than ever.

dodgeball winners


Where? SoMa Recreaton Center 270 6th Street San Francisco, CA

When? Sunday, March 22, 1:00pm until 6:30pm

  • 1:00 to 1:30 - Sign in and warm up
  • 1:30 to 4:30 - Round Robin Tournament play
  • 4:45 to 6:00 - Single Elimination Round
  • 6:00 to 6:30 - Awards ceremony
  • 7:00 to 10:00 - After-party at GitHub HQ (88 Colin P Kelly Jr. Street, San Francisco).

Why? In 2013, 20 teams joined us to compete on the dodgeball court, all in the name of charity. Heroku prevailed for the second time and brought home the Octotrophy, but the real champions are those who received some of the $58,000 we raised!

We're headed back to SoMa Recreation Center and we're devoted to making this year's tournament the best yet. The buy-in to enter is $3,000, and all funds will be split among the charities.

How? We'll be using the World Dodgeball Society's rules for our 2015 tournament. Teams will need 10 players on court during gameplay, but can have up to 15 members per team to allow for player substitutions. Teams must have at most a 3:1 ratio of men to women.

Who? We will all be playing for four local charities. Donations are managed by Bright Funds.

  • Build BUILD's mission is to use entrepreneurship to excite and propel disengaged, low-income students through high school to college success. In 2002, BUILD became a key player in school districts when it went into local high schools and began offering its entrepreneurship curriculum as a daily, credited class. By working closely with the partner schools and their teachers, BUILD began supplementing students' traditional education with the real-life experience of running their own small businesses.

  • SF Public Library The SF Library system is pretty amazing. Not only are they one mega, open source of information and learning in the sense of lending books, music, etc., but they also have all kinds of others programs to support the community. It is also one of the few places people can go and use computers for free. Finally, it often doubles as safe space for at risk youth and the homeless population.

  • Second Harvest Food Bank Collects and distributes more than 1 million pounds of food throughout the Bay Area EACH WEEK. They are feeding thousands of families, many of which are struggling to pay high local rents, etc.

  • Glide Glide provides many kinds of services to anyone who needs them, from shelter, to healthcare, to overcoming violence.

Dodgeball Tournament 2013: After the Action

If you joined us for our third annual dodgeball tournament last Sunday, we thank you and your team, and we hope you had as much fun as we did. It was a great day, and we raised a lot of money for some awesome causes.

Heroku ultimately prevailed and took home their second OctoTrophy! We couldn't host the event without the participation of the community, and we’d like to thank all of the companies and organizations that came out and took some hits for charity: Heroku, Constant Contact, Twilio, Atlassian, New Relic, Pivotal Labs, Thumbtack, Perforce, HRK, Andreessen Horowitz, Goldman Sachs, Go Daddy, Outcast Agency, and Airbnb.

And, if you haven’t gotten a chance yet, take a look at the 4 fantastic non-profits that we chose to support this year: Streetside Stories, Second Harvest, Year Up, and Family House.

Additionally, we owe a huge “thanks!” to the World Dodgeball Society, for serving as incredible referees and just generally being awesome; SportNGIN, whose easy-to-use bracketing system was the backbone of our scheduling and scoring method; Slider Shack, who supplied all-you-can-eat tater tots and mini-burgers to our hungry athletes; and Garden Creamery, who soothed their wounds and their pride with tasty cold treats.

GitHub Game Off II

We ran our very first game jam last year and had so much fun, we decided to throw another one!

GitHub Game Off Game Jam

The Challenge

You have the entire month of November to create a web-based game loosely based on the theme "change".

What do we mean by loosely based on "change"? We literally mean, loosely based. Some examples might be a FPS where you throw the loose change in your pockets at the enemy or perhaps a puzzle game where you have to change form to overcome obstacles.

Your game. Your rules. You can participate either as an individual or as a team. You're encouraged to use open source libraries, frameworks, graphics, and sounds in your game.

The Prizes

We're giving away shiny new iPad Airs (16GB models) to our 5 lucky winners. Runners-up will receive a $100 credit for the GitHub Shop, where they can grab some of our :octocat: shirts, hoodies, stickers, and more!

All winners and runners-up will be showcased on our blog.


We have a handful of judges who are eager to play your games!
