Strategic Brain Utilization: Mastermind

By Cheryll Tefera


Wood and Stewart (famous researchers) published a research in 1987 that shows the benefits of Mastermind. The study showed that college students who participated in the research enhanced their critical thinking abilities, making them less prone to errors in reasoning. Games capture the ideas and worldviews of their cultures and pass them on to the next generation. Games were important as cultural and social bonding events, as teaching tools and as markers of social status. As pastimes of royalty and the elite, some games became common features of court culture and were also given as gifts. There are many varieties of board games. Their representation of real-life situations can range from having no inherent theme (e.g. checkers), to having a specific theme and narrative (e.g. Cluedo). The time required to learn to play or master a game varies greatly from game to game. Learning time does not necessarily correlate with the number or complexity of rules. The rise in board game popularity has been attributed to quality improvement (more elegant mechanics and graphics) as well as increased availability thanks to sales through the Internet. Linearly arranged board games have been shown to improve children's spatial numerical understanding. This is because the game is similar to a number line in that they promote a linear understanding of numbers rather than the innate logarithmic one. The board games can be therapeutic and paying games have been suggested as a viable addition to traditional educational curriculum.

Mastermind resembles a game that was mainstream prior many years. It was named as Bulls and Cows. It includes two players who are included in interpreting the purported codes of one another. Mordecai Meirowitz developed this game in the year 1970. Mordecai was a famous Israeli telecom master and an acting postmaster! Mordecai Meirowitz is considered as a Board Game geek by many. Game of the year (1973), Design Center Award and Queen's Award for Export Achievement are three of the major recognition awards won by this wonderful board game!

Mastermind is a very unique game in its own right, which is played utilizing a disentangling board. This board has a shield toward one side covering a line of four vast openings, and twelve (or ten, or eight, or six) extra lines containing four extensive gaps beside an arrangement of four little gaps. Also, code pegs of six (or more) distinctive colors, with round heads, which will be set in the expansive gaps on the board are needed. Finally, key pegs, some shaded dark, some white, which are level headed and littler than the code pegs are required to be put in the little gaps on the board. There are 1296 different ways of choosing four pegs, where each one is chosen from six colours.(6x6x6x6 = 1296 ways).

The two players decide in advance how many games they will play, which must be an even number. One player becomes the code-maker, the other the code-breaker. The code-maker chooses a pattern of four code pegs. Duplicates are allowed, so the player could even choose four code pegs of the same color. The chosen pattern is placed in the four holes covered by the shield, visible to the code-maker but not to the code-breaker. The code-breaker may have a very hard time finding out the code.

Twelve (may be even ten or eight) turns is what the Code-breaker gets to unravel the pattern deployed by his counter-part. He does so by arranging a row of code pegs on the disentangling board. Then, the Code-maker comes into picture by deploying 0 to 4 key pegs in the small holes of the row. If this key peg is colored or black, it implies that the prediction of the other player is precise both in terms of color and position, whereas, a white key peg specifies the possibility of right color deployed in the incorrect spot.

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 speculation and disentangling goes ahead until one of the thing happens, either the Code-breaker comes up short on his chances or he predicts the accurate example sent by the Code-creator. The scoring is such that the Code-creator is recompensed a point for every prediction that the Code-breaker makes. A reward point is allowed to the Code-producer if the other player doesn't disentangles the right example in the last chance available at his disposal. The victor is clearly the person who has most number of points in the wake of completing the pre-chosen number of rounds. Indeed, even the score rotating around hued key pegs set can be utilized.

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.

Online versions have recently overtaken the popularity of board versions. Many companies have used different combinations of pieces and colors to avoid infringements pertaining to Intellectual Property Rights. If the unoccupied parts (holes) of the board are treated as another color, it would definitely lead to a more intense battle between the player.
