I have an actual blind friendly hardware puzzle I bought at CSUN. What
ticks me off is I know how to do the thing but it takes me forever. My
wife
on the other hand sits down and goes blink blink blink and done. Grrrr.
If
you're interested in buying one let me know I will dig up the place that
sells them. They have Braille squares so you can feel them and you can
get
a couple types some have numbers some have words.

Subject: Re: math behind a puzzle
I get a sense of the puzzle's components, but I don't follow what
actually constitutes solving the puzzle. Can you be a little more
specific?

Hi all,
While this is not strictly programming, I wonder if anyone can point
me to a place where I can find out about a general solution to a
puzzle. The puzzle is simply eight tiles, each of which can be slid
up, down, left, or right. They are numbered 1-8 and are on a grid with
9 squares, so one square is empty to let the pieces slide. There has
to be a mathematical way of figuring out (A) how many moves would be
required to solve this and (B) what those moves are.
Again, this is not programming, but I suspect that I will eventually
run into something like it on http://www.projecteuler.net...
