The computer chooses 4 colors and then you have to guess them...Its really fun...
theres a small problem though....
When you guess one of the colors correct at the correct position, the computer has to add one black dot at the side, and when you gues one color correct but on the wrong place it adds a white dot...
the problem with this is that if for example you guess the first color correct and the 3rd color is the same but you didnt gues that color at all it shall not add a white dot for that color (being half correct and fully correct at the same time)...
also if you guess the first correct and then guess that color later but its not at any more place in the computers colors it shall not get a white dot
its pretty hard to explain but youll probably get the idea if you play it
