Code Master

Code Master is a board-style game where you must find a secret code using your logical reasoning skills.
The secret code is a sequence of four balls of eight different colors and you must guess the exact code in at most 10 turns.

In each turn you make a guess of what is the sequence and the board will give you some feedback: it will show a black ball for each colored ball you have placed correctly and a white ball for each ball of a color that is present in the code but that you have not placed it correctly. Try to eliminate the wrong colors in order to find the correct code.
