The aim of the game GeniusExpert is to guess the secret code of the PC which consists of 4 coloured pegs (6 various colors). In every round, the player has to guess and tells him, with the aid of white and black indication pegs, how close his guess was. A white indication peg signifies, that the colour of the peg is right, but the position wrong. The black indication peg shows that the peg matches the PC code.
