The goal of this board game is to break a code using obscure hints. The game is played by 2 players: the codemaker (the computer) and the codebreaker. The computer generates a combination of 4 colors. The codebreaker has to guess that pattern (both order and colors) with the least number of tries. At each turn, the codebreaker tries a pattern and the computer provides feedback by placing pegs in the score grid. A white peg indicates a right color but wrong position; a colored peg means that both color and position are correctly guessed.
