Intricacies In Mastermind Game

By Cheryll Tefera


For the longest time, playing board games has been linked with the development of the mind, especially in young people. According to Dr. Gwen Dewar of Parenting Science, games such as chess and Mastermind help hone a person's logical-mathematical intelligence - brilliance that is often found in scientists, mathematicians and investigators. The history of games dates to the ancient human past. Games are an integral part of all cultures and are one of the oldest form of human social interaction. Games are formalized expressions of play which allow people to go beyond immediate imagination and direct physical activity. A board game is a game that involves counters or pieces moved or placed on a pre-marked surface or "board", according to a set of rules. Games can be based on pure strategy, chance (e.g. rolling dice), or a mixture of the two, and usually have a goal that a player aims to achieve. While the board gaming market is estimated to be smaller than that for video games, it has also experienced significant growth from the late 1990s. A dedicated field of research into gaming exists, known as game studies or ludology. While there has been a fair amount of scientific research on the psychology of older board games (e.g., chess, Go, mancala), less has been done on contemporary board games such as Monopoly, Scrabble, and Risk. Research studies show that board games such as Chutes and Ladders result in children showing significant improvements in aspects of basic number skills such as counting, recognizing numbers, numerical estimation and number comprehension.

Mastermind is similar to a game that was popular hundreds of years ago which was named as Bull and Cows. It involves two players who are involved in deciphering the so-called codes of each other. It was invented in the year 1970 by an Israeli telecommunication expert named Mordecai Meirowitz. He was an acting postmaster too! His idea was at first turned down by many of the leading toy companies, but he persisted, and took it to the International Toy Fair at Nuremberg in February 1971. Released in 1971, the game sold over 50 million sets in 80 countries, making it the most successful new game of the 1970s. It has received awards like Game of the year (1973), Design Center Award and Queen's Award for Export Achievement.

Mastermind is an extremely game in its own distinctive way, which is played using an unraveling board. This board has a shield toward one side covering a line of four inconceivable openings, and twelve (or ten, or eight, or six) additional lines containing four broad crevices alongside a course of action of four little holes. It also comprises of code pegs of six (or more) unmistakable shades, with round heads, which will be set in the far reaching holes on the board are required. It also encompasses, key pegs, some shaded dim, some white, which are practical and smaller than the code pegs are obliged to be placed in the little holes on the board.

One of the two players becomes a Code-maker and the other is Code-breaker. It is chosen at the start between these two players that how many rounds of game they will play. It is to be noted that the number of rounds to be played must be an even number. A pattern of four code pegs is then chosen by the Code-maker, since the replicas are permitted, the player has an option to deploy these pegs of the same color. The pattern is arranged in the four holes by the Code-maker and is hidden from the Code-breaker. This ensures that the Code-breaker finds it very difficult to decipher the enigma!

The code-breaker tries to guess the pattern, in both order and color, within twelve (or ten, or eight) turns. Each guess is made by placing a row of code pegs on the decoding board. Once placed, the code-maker provides feedback by placing from zero to four key pegs in the small holes of the row with the guess. A colored or black key peg is placed for each code peg from the guess which is correct in both color and position. A white key peg indicates the existence of a correct color code peg placed in the wrong position.

There may be an occasion when there are comparative hues in the predication set out the Code-breaker and it is not doable to concede a key peg to every one of them unless they coordinate the definite number of comparative shading in the shrouded code. It should be noted that, if the concealed code is B-B-A-A and the Code-breaker demonstrates A-A-A-B, the other player should award two hued key pegs for the right B, nothing for the third B lastly, a shaded key peg for the last A. This guarantees, that the anticipation of the players is kept alive, concealing the way that the code has a second B in it! Here A and B are hues that may be utilized as a part of the table board.

This pattern of guessing, unraveling goes on until one of the thing happens, either the Code-breaker runs out of his chances or he predicts the exact pattern deployed by the Code-maker. The scoring is such that the Code-maker is awarded a point for each prediction that the Code-breaker makes. A bonus point is granted to the Code-maker if the other player doesn't unravels the correct pattern in the last prediction. The winner is obviously the one who has most number of points after finishing the pre-decided number of rounds. Even the score revolving around coloured key pegs placed can be used.

There have been many mathematicians involved in researching concrete solutions to this game. Many number of algorithm have been presented on the world stage. Michiel de Bondt has used one in three 3SAT basics to prove that it can be solved by NP-complete logic. By examining different probabilities to deploy different number of players on the table, more number of holes on the game-board and another set of substantiated colors, different versions of this game have come into existence. Mastermind Secret Search (1997), New Mastermind (2004) and Mini Mastermind (2004) are its latest types.

The difficulty level of any of the above can be increased by treating "empty" as an additional color or decreased by requiring only that the code's colors be guessed, independent of position. Computer and online versions of the game have also been made, sometimes with variations in the number and type of pieces involved and often under different names to avoid trademark infringement.
