I'm still desperate for responses to this logic puzzle (I want to compare the results to a different form of the same puzzle, that had 200,000 responses!). So if you haven't done so already, please consider spending a few minutes trying to solve it. It's good for your brain :)

Please distribute widely. I will share the results and their implications for HCI and User Experience.
