Judging Criteria for Build’n Play Part 2: The Hackathon

The Spirit of Build’n Play

Build’n Play is about finding and incorporating joy and playfulness into every interaction. Whether you’re building a language learning game, a better incentive to wake up in the morning, or an app for your five-year-old niece, we want to see games that put smiles on everyone’s faces, that are inspiring, unique, and, above all, fun.


Leveraging open source resources is strongly encouraged, but all submissions must be built within the time frame of Build’n Play alone (7pm October 4th – 7pm October 5th). With the exception of partner-specific API prizes, participants do not need to incorporate Partner APIs or data sets to win. Team projects must be listed on our Hackerleague Projects page by 7pm on October 5th to be considered.

Anything you build will belong to you; neither we nor our sponsors have any rights to your work.

Teams can be any size and composition but we think 3-6 people per team is the most productive and we encourage teams of half women and half men.

Judging Criteria

Completeness (25%): Does it work? How much of the game has been built?

Fun (25%): Is it fun to play? How much do you want to keep playing it?

Design (25%): Does it look good? How much visual and aural appeal does it have?

Concept (25%): Is it a unique idea? How well thought out or different is the story or gameplay?

What Kind of Game Will You Build?

Part II of Hack’n Jill’s Build’n Play a gaming-focused hackathon on October 4-5.

Your first question might be: what kind of game would I make?

There are a ton of options outside the universe of Lara Croft, Mario, and Halo. We’ve even seen a wide variety come out of our previous non-gaming hackathons. For examplebig water slides for sale:

Two of the speakers at Build’n Play Part 1 are co-creators of popular games:

  • SiSSYFIGHT 2000 (Naomi Clark): destroy the self-esteem of 2-5 other players

  • Dots (Patrick Moberg) – preposterously simple, harder to quit than e-cigarettes.

For further inspiration, we’ve gathered examples of different games and types of gameplay from around the web.

See a Picture, Guess Where it’s From

Commonly used for with mapping and geography, this could also be extended to other categories. For example, Halloween or Williamsburg (currently only available as a blog), where you see a picture and guess whether it’s from from Halloween or Williamsburg.

  • GeoGuessr: start at random place on google maps, guess where that place is

  • ViewFinder: look at photos from Instagram, guess where they are from
  • Where On the Blue Earth: see a photo from NASA, guess the place on the globe

Digital in Real Life

These games often use geolocation to augment your boring normal life. If fiction is any predictor, soon these will be embedded in our brain-computers. For now, these games are usually on your phone.

  • Zombies, Run!: motivates a run by pretending “zombies” are coming

  • Red Cloud Rising: investigate a Wall Street cabal through calls and texts.

  • uChoos: choose your own adventure through SMS

  • SXSWrpg: turns SXSW into a quest through Twitter

Words and Typing

Instead of point and click, these games revolve around the keyboard. It’s helpful (but not strictly necessary) to have facility with words too.

Break the Page

When you spend a lot of time on the web, sometimes you just want to break the page. Add these games to your bookmarks, launch them on a page you hate (Facebook?) and feel some catharthis.

  • Kick Ass: destroyer planes remove pieces of a page

  • Katamari Hack: roll a ball around the page, growing bigger and bigger

Design Your Own Game

In these games, you draw key pieces of the environment or objects used in the game.

  • Line Rider: draw a wicked ride for a sledder

  • Gear Sketch: build a magic machine with gears and chains

  • Ball Droppings: bounce balls dropping from the sky by drawing lines

  • BoxCar: build a bad car and watch it evolve into an awesome car

Timing It Right

These games are games of precision, pure and simple. Who knows why games like these are so appealing? Perhaps they bring us closer to the human ideal. Perhaps, if we can just get X thing to stop at exactly Y time, then the partner of our dreams will finally notice all of our sparkling personality traits. Or maybe they’re just fun.

Click and Destroy

Life can be a stressful thing, and in these over-civilized, lily-livered times, it’s considered downright indecorous to release your stress in the form of wanton rage. So let loose in one of these shoot-em-ups, before all the pressure breaks you down and you end up like that Kony 2012 dude.

  • Bacon Game: bacon is falling from the sky, click to explode it (Counterintuitive, we know — why aren’t you catching the bacon and packaging it into pricey sandwiches to hawk at the Brooklyn Flea?)

  • Rawkets: multiplayer space shooter

  • Disateroids

Go on an Adventure

Adventure stories are oldies but goodies. Tap into people’s volunteer instincts and let them help an imaginary friend achieve things far beyond the realistic real-life achievements of normal humans!

  • Browser Quest: a multiplayer adventure with swords and sorcery

  • Robots Are People Too: two player cooperative game

  • Convergence: bring two characters together

  • Sinkhole: gratify your inner spelunker and navigate through a cave with only a unidirectional headlight to guide you.

And More

There are many other types of games we haven’t mentioned like puzzle games, number games, racing games, sports games, music games, etc., etc. Come out in October and make a game you’re passionate about. Now we have to end this post to go play Dots for several hours…

Why We’re Doing a Gaming Hackathon

Something’s up in the state of gaming. Women represent 45% of all gamers. Women gamers over age 18 outnumber male gamers under 17 by nearly two to one.

But women comprise only 11% of game designers, and 3% of game developers.

Maybe that’s why Microsoft didn’t release a single game with a female protagonist this year. Or why 85% of playable characters in video games are male.

It’s tough to build games. It’s even tougher to feel marginalized, unwelcome, objectified or downright harassed while doing so.

We need a safe place to play—and to build.

On October 5 and 6, Hack’n Jill will be hosting a hackathon where 50 men and 50 women will come together to build and play.

We’re establishing a safe space where anyone who’s curious or passionate about games and gaming can learn, collaborate, and create.

We’re doing this because we bring people together who care about the composition of the room. We believe in mindful development and design. We believe having a different perspective provides inherent value.冰熊水滑梯

So come out and join us.

Build something fun in 24 hours.

Present your work in front of 99 people.

Make a team of soon-to-be-friends.

We want you—your ideas, your point of view, your expertise—at the table.

Next Hackathon

We’ve got some good news and bad news. Bad news first: we won’t be doing a summer hackathon :( :( .

Good news!: Our next hackathon will be a GAMECHANGER. We’ll be getting a 50/50 group of men and women together to hack on gaming! This is everything from mind controlled video games to virtual international travel to waking up in the morning to New York scavenger hunts.

We’ll have a evening prep event in September and then the hackathon will be October 4th-5th. Get ready inflatable water slide for sale!

Happy First Birthday, Hack’n Jill

It’s official. Hack’n Jill is now one year old! It has been an incredible year for us, and we want to thank all of you for being such amazing supporters of the movement towards a more diverse tech community Inflatable Castles.

In the beginning…

A year ago, we (Kara, Eugenia, Lauren, and Judy) were strangers to each other and to you. We were brought together by Aaron Smyth who thought we “might want to work on something for women in tech” and serendipitously, he was right.

In the beginning, we barely knew what we were doing; it took a month’s worth of weekly meetings just to decide our name. Rejected names include: Let’s Hack It out, Lady and the Hack, Hack to the Future, 50/50 Exception Committed, Sadie Hackins, and Affirmative Hacktion. Yes, these were the results of hours of brainstorming (but no, we don’t do brand consulting, so go ahead and put your checkbook away).

The rest, as they say, is her-story (that’s a pun).

The keys to success…

1. Teamwork
Like an arranged marriage, sometimes the best matches are the ones that are chosen for you. For anyone who has worked on a team, you know how wrong it can go in so many ways. We have been so lucky to have stumbled onto each other. A year ago, we were a bunch of strangers with no experience in community building. Since then, we’ve disagreed productively, relied on each other, and learned along the way how to throw hackathons, happy hours, and twitter feuds.

2. Purpose
We don’t do Hack’n Jill for the money or the SXSW after parties—or because we can’t think of any other way to spend our nights and weekends. We do Hack’n Jill because we believe in it. We believe that a diverse team is happier and more productive. We believe that there are problems with the proportion and visibility of women in tech. We believe we can show the tech community something new.

3. Community
It’s a testimony to the NYC community that a new idea received so much support, especially at the beginning when there was no evidence that we would succeed. Our first partners (SendGrid, Twilio, AppNexus, Yodle, Microsoft, Temboo, Yipit, Boxee, Mashery, StackOverflow) hold a special place in our heart for believing in us. As we continue, we see more and more how enthusiastic and generous our community is.

Looking back…

With your help and support, we are so proud of what we’ve done this year.

We are so excited to be working with all of you. Thanks for your role in changing the world; you never cease to inspire us.

The best has yet to come.
