The Illinois-based company didn't intend to keep a cent of its holiday profits. Instead, the game's founders wrote a cheque for $70,066.27 to Wikimedia, the corporation behind Wikipedia.
"Wikipedia is very important to us because without it we would not have known the exact volume of a dose of fresh boar sperm or graduated college," Cards Against Humanity's founders wrote on the site.
"From the outset we decided we wanted to give all the proceeds to charity and that made it more fun for us," Max Temkin, co-creator of the politically incorrect game, told the Guardian. "We weren't really worried about the bottom line, we were really able to do it as an experiment and do it in a great way."
The Cards of Humanity creators posted an infographic on their site explaining the company's profits and offering zany suggestions as to how to spend the them.
"We wanted to pick something we thought the users of our game of had heard of and believed in and used and we felt like Wikipedia is pretty unique in terms of having universal appeal," Temkin added. "It's something that helps a lot of people of all different classes and levels of education in different places all around the world...We also support the social mission of Wikipedia."
Wikimedia Foundation founder Jimmy Wales tweeted an ecstatic response to the generous donation:
"OMG this is so f***ing cool. Scroll to the bottom. Cards against Humanity, you are the best. ow.ly/gb5H2"
"I can't even tell you how we were freaking out yesterday when he tweeted about us," Temkin said of the tweet. "$70,000 is a lot for a game like us, but it's still pretty small, we weren't sure it would move the needle for Wikipedia or not, so it was really cool to hear from him."
Cards Against Humanity currently sells for about $25 on Amazon, where it regularly sells out, but is also available as a free download under a Creative Commons license.
The game was launched following a successful Kickstarter campaign in early 2011. Donations started the company, and now it's paying it forward.
