Amazing Brain Exercise: Mastermind Board 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 a board game with an interesting history. Some game books report that it was invented in 1971 by Mordecai Meirowitz, an Israeli postmaster and telecommunications expert. After many rejections by leading toy companies, the rights were obtained by a small British firm, Invicta Plastics Ltd. The firm originally manufactured the game itself, though it has since licensed its manufacture to Hasbro in most of the world. However, Mastermind is just a clever re-adaptation of an old similar game called 'Bulls and cows' in English, and 'Numerello' in Italian. Actually, the old British game 'Bulls and cows' was somewhat different from the commercial version. It was played on paper, not on a board. Over 50 million copies later, Mastermind is still marketed today! It went on to win the first ever Game of the Year Award in 1973. It also received a Design Center Award, and the 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.

It is picked toward the beginning between these two players that what number of rounds of the game they will play. One of the two players turns into a Code-creator and the other is Code-breaker. It is to be noticed that the quantity of rounds to be played must be an even number. The odd number of games is not possible as it would ensure that one of the players does not have equal chances compared to the other personnel. An array of four code pegs is then picked by the Code-creator, since the imitations are allowed, the player has an alternative to convey these pegs of the same color. The array is organized in the four openings by the Code-creator and is concealed from the Code-breaker. This guarantees that the Code-breaker thinks that it's extremely hard to decode the conundrum!

Now the actual game of 'cat and mouse' begins. Twelve (may be even ten or eight) turns is the thing that the Code-breaker gets the chance to disentangle the arrangement conveyed by his partner. He does as such by organizing a column of code pegs on the unraveling board. At that point, the Code-producer comes into picture by conveying 0 to 4 key pegs in the little gaps of the column. On the off chance that this key peg is colored or black, it suggests that the forecast of the other player is exact both regarding shading and position, while, a white key peg indicates the likelihood of right shade sent in the off base spot.

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. For example, if the hidden code is white-white-black-black and the player guesses white-white-white-black, the code-maker will award two colored key pegs for the two correct whites, nothing for the third white as there is not a third white in the code, and a colored key peg for the black. No indication is given of the fact that the code also includes a second black.

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.
