[Immi666]

i have this puzzle thing where there are three frogs facing one way and three frogs facing the other way and there's one space between them. and u have to move the three on the left to the right side and the three on the right to the left side, by leap frogging them. i have no idea how to do it. does anyone know what i'm on about? and do they know how to solve it?

I think this is a well known puzzle and there is an on-line version of this puzzle at http://www.hellam.net/maths2000/frogs.html

If its the same puzzle you change positions by using a mixture of jumps over a frog to a vacant lily pad or slide to a vacant neighboriing lily pad.

The solution for 3 of each starts: slide, jump, slide, jump, jump, slide.
You should now have the frogs intermixed with a vacant lily-pad at one end.
The total number of moves required is 15 (9 jumps & 6 sldies)
