The Kickstarter for Exploding Kittens is only a few days old, and already it has pulled over USD$3 million. And the count is rapidly climbing.
Exploding Kittens is a card game by Elan Lee (XBOX), Matthew Inman (The Oatmeal), and Shane Small (XBOX, Marvel). Players draw cards until they draw a kitten, at which point they lose. All the other cards can be used to defend, attack, skip your turn, or defuse the kitten using various action cards. It sounds like a simple mechanic, but obviously there is something about this game that has attracted not only the usual tabletop card players, but scores of regular people too.
You can learn more about Exploding Kittens on the website, or get in on the action on the Kickstarter.
