Thursday Brain Tease

Recommended Posts

It's early and I can't figure this out. I'd attach the file but it's too big.

You have 7 rocks in a pond.
On the 3 rocks on the left you have green frogs facing right.
On the 3 rocks on the right you have red frogs facing left.
The middle rock is empty.
The frogs can only jump in the direction they are facing.
They can only jump over one frog at a time, so there must be an open space for them to land.

How do you do it so the frogs switch sides?

I think you should just kill all the frogs and make frog legs... :D

j/k... I know how to do it... but why should I tell you...

it seems someone else answered it... and I had a mistake in my description...
