Superhirn (C64)

How to play?

You have 10 rounds to guess a code of four colors.

After you put in your guess confirm with <RETURN> button which will give you a result:

White circle(s): one or more right colors on the right positions.
Black circle(s): one or more right colors, but on wrong positions.
No circle(s): wrong colors

The order of the circles in the evaluation row does not refer to the position of the pins in the code row but is always from left to right!

Can you hack the code?
