I'm... a bit at a loss of words for this one.
You take little, folded cats, and build a tower out of them (kinda spoiled in the name of the game).
IDW Games is running a Kickstarter campaign now for it.
There's actually a couple ways to play. You can go the "standard" route where you all add cats to a central tower until it topples. Or you can each try and build your own cat tower as fast as possible. First one to get one standing for more than 2 seconds wins.
This is a pretty short campaign, with only 17 days left to get in on the action.
