The object of this game is to guess the sequence of a number of colored pegs the computer has selected at random. You can select with how many different colors and how many columns you want to play (3 - 7 each). With the number of colors and/or columns you can raise the severity code.
You start filling the holes at the bottom row with pegs, and each time you have completed a guess (i.e. filled all holes) the computer will respond by giving you one peg for each correct color - black if your guess was also in the right place, otherwise white - but you will not be informed about which colors and which place were correct. That part you will have to figure out for yourself.
