GWAP: 2008-2011

GWAP (for Games With a Purpose) was an academic project at CMU that explored the idea of Human Computation games to solve problems that computers cannot solve.

Over 200,000 people played games here, but unfortunately the creators decided to move on to other projects.

Your Games and our Algorithms

We haven't added many updates to the blog, but have been busy
with several things behind the scenes. Over the past year we have been
able to put your games to good use towards improving the state of computer science: check out some of the things we've done here and here.

Thank you for playing, we hope that you enjoy the games as much as we
love playing with the data!

Global Chat and Comments

We're happy to announce the release of a global chat room on We hope you enjoy it as much as we are!

For now, we won't let players chat while they're playing a game, but you can chat before and after each game. On the right of the chat window you'll see a list of the people who are currently viewing the conversation.

If for some reason you'd rather only play the games and not chat, you can always minimize the window to log out of chat. will remember this, and next time you come to the site the window will be automatically minimized.

Also, we now allow you to leave comments on our news stories. We want to hear from you!

Hello World

Sixteen months, 103,417 lines of code, 154 meetings, 1,034 cans of Mountain Dew, and is finally here!

The Name. Yes, GWAP is a little weird as a name. Partly because we're a little weird ourselves, and partly because it's impossible to get a decent domain name. GWAP stands for "Games With A Purpose", a phrase coined by Lenore Blum to describe the types of games found on this site.

The Purpose. The games on this site all have a common purpose: to make computers more intelligent. As you play the games, you are teaching computers things that they don't know yet. Please help them learn!

The Team. The person who made this site possible is our chief engineer, Mike Crawford. He agreed to move from Australia to Pittsburgh to work on this project -- ha! In addition, Michael Brotzman, Severin Hacker (yes, his last name really is Hacker), Edith Law, Bryant Lee, and Edison Tan all spent countless hours architecting the games and the site. Ryan Staake was our ninja graphic designer.

The Past. is brought to you by the same people who created The ESP Game (a.k.a., the Google Image Labeler), Peekaboom and reCAPTCHA.
