Geocache Description:


The above coordinates are not for the final location!


It is said that Mastermind was invented in 1970-71 by Mordecai Meirowitz, an Israeli postmaster and telecommunications expert. However, it is really just a clever adaptation of an old game played on paper called " Moo" or "Bulls and Cows".

A game called 'Moo' was used on the Cambridge Titan shared computer system to help develop security applications by tempting hackers to modify the 'Moo League' of scores as a harmless diversion. The game involved guessing four numbers, scoring 'Bulls' or 'Cows' for correct numbers in the right or wrong places. Dr John Billingsley perceived that the game could be played equally effectively by his children with pencil and paper. Some time before 1976 he was engaged in a consultancy with Invicta Plastics, whose products at the time featured plastic inserts for footwear. He was asked if he could think of a game that could use their technology and the game of Moo sprang to mind. At the time, the TV quiz show Mastermind was in vogue and he suggested that name, never believing that it would be permitted. He influenced the design of the board, insisting that the 'results' pegs should be arranged in a square rather than in a line, to avoid each result being associated with a particular guess peg. Thinking that the game was 'public domain' or that the rights belonged elsewhere, he was unwilling to make any claim for it. Since then Mastermind, named Game of the Year in 1974, has sold in tens of millions in many versions, and continues to be immensely popular in homes world-wide.

The idea of the game is for one player to guess the secret code chosen by the other player. The codebreaker has to try and guess the pattern of colored code pegs that have been chosen by the code-maker; duplicate colors are allowed. Each guess is made by placing a row of code pegs on the decoding board. Once placed, the code-maker provides feedback in the form of black and white key pegs. A 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. If there are duplicate colors in the guess, they cannot all be awarded a key peg unless they correspond to the same number of duplicate colors in the hidden code. The positioning of the key pegs has no bearing on the position of the code pegs.

To get the final and parking coordinates for this cache, you will need to play at least two rounds of the game, one for north and one for west. The links below will take you to online, interactive boards which also contain better examples for gameplay.


Enjoy and happy hunting!
