This game is played like the classic logic game
MasterMind.
My version features the ability to change the size of the code
(from 3 pegs up to 6 - why in the world would anyone want to go higher?),
to change the number of colors available (from 3 up to 10),
and to disallow repeated colors in the secret code.
You can also choose whether you want the scoring pegs to be black-and-white
(which I think is the classic version) or red-and-white.
You should also check out the nice piece-grabbing effect I have implemented.
It's a variation on 'mouse-following' behavior, but turns on and off
according to relevent events (like clicking on an unplayed peg). I also
made it so you can put pegs in and take them back out while you are thinking,
and shuffle them around and so forth, before committing to a guess.
I hate it when these games restrict peg play to be left-to-right,
or they score your guess the instant the last peg is played, without
letting you review your guess.
This game is programmed in javascript.
