1. ## Leap Frog Puzzle

The site says it's a second grade test in China. I couldn't figure it out. Guess I'm not that smart. Anyone else ???

2. ## Re: Leap Frog Puzzle

It can be solved with a combination of trial and error to see how it works and reasoning, but I wouldn't qualify it as suitable for second grade pupils...

3. ## Re: Leap Frog Puzzle

I worked with another video puzzle earlier this year that involved moving people across a stream on a raft with restrictions on numbers and combinations of people permitted on the raft and on each shore. It was claimed to be a Japanese job interview test. Took me a while, but with trial & error and reasoning I solved it. This one completely stumped me. <img src=/S/newbrain.gif border=0 alt=newbrain width=21 height=22>

I think this is easier to see than the way Hans wrote it out:

Thanks !!! I always knew your hands weren't your only amazing characteristic. <img src=/S/clever.gif border=0 alt=clever width=15 height=15>

Only if your provide the key to solve your puzzle. <img src=/S/laugh.gif border=0 alt=laugh width=15 height=15>

Seriously, that is more visually clear and you can "see" the solution more clearly and not do the puzzle to see the solution. At least for those of us with IQ's under 200.

8. ## Re: Leap Frog Puzzle

I guess I could have explained that it was the "view" after each move....

9. ## Re: Leap Frog Puzzle

I don't think that was necessary. It's pretty obvious after a moment's thought (for me at least) what the graph represented. It became even more clear when I pasted the graph into a document and stretched it to the right and centered each letter in it's box. <img src=/S/grin.gif border=0 alt=grin width=15 height=15> <img src=/S/clever.gif border=0 alt=clever width=15 height=15>

10. ## Re: Leap Frog Puzzle

It's a lot like the Three Pyramids puzzle - with a pyramidal stack of discs on the middle of 3 posts, and you have to move them to one of the other posts moving only one at a time, and never putting a larger disc on top of a smaller disc. Once you get the hang of it. it's easy.
Of course, the trick is always in getting the hang of it. <img src=/S/grin.gif border=0 alt=grin width=15 height=15>

Thanks for that Don. <img src=/S/razz.gif border=0 alt=razz width=25 height=17> <img src=/S/laugh.gif border=0 alt=laugh width=15 height=15> That's the reason I posted this.

12. ## Re: Leap Frog Puzzle

<img src=/S/whisper.gif border=0 alt=whisper width=29 height=17> You can't just move each piece like in that annoying marbles in a triangle puzzle, where you keep jumping until only one is left; you need to set up your next move after each jump - at least until you're halfway home.

13. ## Re: Leap Frog Puzzle

I was stuck on the third move. Just couldn't "see' it. <img src=/S/shrug.gif border=0 alt=shrug width=39 height=15>
