Sliding pennies #1 (Posted on 2005-05-31) Difficulty: 3 of 5
Six pennies are arranged in the pattern of O's below.

Nearby pennies are touching. By the fewest number of legal moves, transform the pattern into the pattern

O O O O O O

consecutive pennies touching. A legal move consists of sliding a penny, not picking up a penny, without disturbing the other pennies, to a new position touching at least two pennies. (You might want to look up Moving Quarters for a similar problem with the same rules.)

I got three. | Comment 5 of 16 |

If I did it correctly, I slid the first one on top over to the side by the first one on the bottom, the second one on top next to that one, and third one on top to the very end.

But I'm stupid, and I really believe that in some way I did it completely wrong. But I just wanted to give it a try. So tell me if I did it wrong.

Plus, I'm not really good at this stuff, I'm only 13.
