Identical Balls
Thanks
Jean B
Start
at square 1.
Move to another square which must contain four balls identical
to those in square 1, and one
that is different.
From this second square, move the same way to a third, and so on until
you've visited all the numbered figures, except one.
Which one?
Answer: #6
Here is the order: 1 - 2 - 5 - 8 - 4 - 9 - 3 - 7
