Mind Master is a simple code-breaking game. The modern game with pegs was invented in 1970 by Mordecai Meirowitz, an Israeli postmaster and telecommunications expert, but the game resembles an earlier pencil and paper game called bulls and cows that may date back a century or more. The game is played using:
- code pegs of six different colors, with round heads, which will be placed in the large holes on the board;
- key pegs, some black, some white, which are flat-headed and smaller than the code pegs; they will be placed in the small holes on the board.
The codemaker (computer) chooses a pattern of four code pegs. Duplicates are allowed, so the player could even choose four code pegs of the same color. The codebreaker (player) tries to guess the pattern, in both order and color, within ten turns. Each guess is made by placing a row of code pegs on the decoding board. Once placed, the codemaker provides feedback by placing from zero to four key pegs in the small holes of the row with the guess. Black key peg is placed for each code peg from the guess which is correct in both color and position. A white peg indicates the existence of a correct color peg placed in the wrong position (to be precise, the number of white pegs is the extra number of black pegs that it is possible to get using exactly the code pegs in that guess.) Once feedback is provided, another guess is made; guesses and feedback continue to alternate until either the codebreaker guesses correctly, or ten incorrect guesses are made.
