The Zebra Puzzle
The Zebra Puzzle is a
well-known logic puzzle.
It is often called
"Einstein's Puzzle" or "Einstein's Riddle" because it is
said to have been invented by Albert Einstein as a boy. Some claim that
Einstein said "only 2 percent of the world's population can solve
it."

has a different nationality, owns a different pet, drinks a different beverage
and smokes a different brand of cigarettes.

only to deduce the answers to the question but to figure out who lives where,
in what color house, keeping what pet, drinking what drink, and smoking what
brand of cigarettes.
