I just wanted to post my frustration at the game. After just math-nelly picking a number of boxes, I thought I figure out how to win:

Let the number of boxes remaining be "B"

if B modulo 3 is equal to 1, pick one box

if B modulo 3 is equal to 2, pick two boxes

if B modulo 3 is equal to 0, you'll lose (assuming that the other player follows the above two rules)

Since the starting point is B = 18 (which is divisible by 3) and since deep grey knows how to play, you can never win.

But keep trying ... you might just win

I typed in w i l l y - n e l l y and it keeps putting it up as hairy-nelly. What gives?

Okay, I'll recant somewhat. After figuring out the method of winning, I assumed that the programmer made **deep grey **smart enough to win every time. Apparently he lapses every once in a while.

Aha! You discovered a secret ... a "human" program

Huh, cool. I just made the same assumption and thought the Deep Grey would always win.

As for the other thing, when random words get replaced by random other words, it's almost certainly the work of the word filter. I'm not sure why the replacement is hair, but that's what's doing it anyway.

Why did the vector cross the road?

It wanted to be normal.

Wow, is this game really hard? I went to try it after reading this and won my first try.

Ok, I think I just found out the trick right away and that's how I won, he hasn't beat me yet. I just get it down to 5 boxes at the end and it's my turn... I pick 2, and whatever he picks I will win. I'm sure sometimes this won't be possible though.

Also, MathsIsFun, I found a bug with this game. Whenever you click "Choose One" or "Choose Two" you take squares, even if it isn't your turn. There's an easy way to win the game too .

Thanks Zhy.

.. fixed it: Deep Grey

(I wonder if there are any cool variations I could make?)

That wasn't hard.

Maybe change the way that the CPU thinks by adding difficulty levels. Perhaps even add a timer so that you have to move quickly. Or a speed game.

Heh, this is pretty easy, the first time I won by clicking 'Pick Two' the whole way, second time I clicked 'Pick One' only at the end.

Difficulty Level sounds good.

That won't get you the win every time, Deep Grey always changes its moves a little bit even if you keep yours the same.

Really? I played it a few dozen times (literally) and its method never changed. Perhaps this is a bug or a glitch needing to be fixed? Perhaps I am wrong myself.

Thus proving that the game 'Deep Grey' is a sorry game...

...

Whatever that may mean, anyway.

That method doesn't work for me.
