Sliding cards brain buster

November 29th, 2006

Wow, I’m still having a hard time wrapping my mind around this one…

A real brain buster created by Marcel Debreuil:

Think you can solve this? It looks simple but the more you look the trickier it gets.

The idea is there are three panels - by switching the top two around you get two pictures. The catch is that although the figures line up, there are a different number of people in each of the two resulting pictures. Below is one I made 15 years ago (man!). The first picture has 13 people, the second only 12. For an extra twist, one person has turned into a fresh steamy dog turd. So the question then is, Who turned to doggie doo?

3 cards separate
“These are the 3 pieces of the puzzle- the top 2 can switch around to make the images below”
3 cards together part A
“Thirteen people, you can count them”

3 cards together part B
“Twelve people, but the dog was busy. So who turned to doggie doo?”

Will post the answer in the comments section in 1-2 days;
