[PacFu]

take 6 equal coins..

arrange them like so, but with no spaces.

O
-O

except they all coins have to touch 2 coins at all times. You have 3 moves to arrange coins in a perfect circle.

-OO
O--O

You can not lift a coin on a move, nor can you move a still coin when moving.

Fun stuff

The end coins aren't touching 2 coins. ...?

 

[blahblah99]

I did it in 2 moves! Beat that!

Maybe I'm dumb, but I don't understand the rules.

From the initial position, there isn't a single "legal" move by your rules stated.

 

[PacFu]

Can't be done in 2 moves...
I think I stated the rules wrong...

The coin you are moving has to touch 2 coins. Others can have only 1 touched.

Here is what the setup should look like...

That's nothing like your ASCII depiction. :roll:

There has to be some 'trick' here. If you can go from one start to finish in 3 moves, you 'should' get from finish to start in 3 moves. But I don't see a single legal move that the finish can take.

Well, that certainly made things a lot easier. Only took a few seconds to figure out.

so.. uh... how do you do it?

Yeah, it's pretty easy now that you clarified. I was thinking that all coins had to touch 2 others at all times (as in while you're moving it). Didn't realize it just had to 'end up' touching two when you moved one.

oh... oh.. I get it now...

Solution? Or at least one variation of it.

Move D to right of E&F
Move E to right of A&B
Move A to connect D&E

I still don't get it. How can you touch two coins "at all times"?

The coin that you're moving has to be placed where it touches two coins. That may leave other coins touching only one.
