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 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.

Something about this game caught the imagination of the public, and it became the most successful new game of the 1970's. The game is played using: a decoding board, with a shield at one end covering a row of four large holes, and twelve (or ten, or eight, or six) additional rows containing four large holes next to a set of four small holes; code pegs of six (or more; see Variations below) different colors, with round heads, which will be placed in the large holes on the board; and key pegs, some colored black, some white, which are flat-headed and smaller than the code pegs; they will be placed in the small holes on the board. In 1993, Kenji Koyama and Tony W. Lai calculated that the best strategy uses an average of 5625/1296 = 4.340 moves.

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 instance when there are similar colors in the predication laid down the Code-breaker and it is not feasible to grant a key peg to all of them unless they match the exact number of similar color in the hidden code. Now, if the hidden code is A-A-B-B and the Code-breaker indicates B-B-B-A, the other player ought to grant two colored key pegs for the correct A, nothing for the third A and finally, a colored key peg for the last B. This ensure, that the suspense is kept alive, hiding the fact that the code has a second B in it! Here A and B represent colors that might be used in the table board.

Once feedback is provided, another guess is made; guesses and feedback continue to alternate until either the code-breaker guesses correctly, or twelve (or ten, or eight) incorrect guesses are made. The code-maker gets one point for each guess a code-breaker makes. An extra point is earned by the code-maker if the code-breaker doesn't guess the pattern exactly in the last guess. (An alternative is to score based on the number of colored key pegs placed.) The winner is the one who has the most points after the agreed-upon number of games are played.

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.

The Best Strategic Game Board Game: Risk

By Cheryll Tefera

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). Rules can range from the very simple (e.g. Tic-tac-toe), to those describing a game universe in great detail (e.g. Dungeons & Dragons) - although most of the latter are role-playing games where the board is secondary to the game, serving to help visualize the game scenario. Even though the rules in 'Risk' strategic game are simple to understand, it doesn't take away from the fact that it is extremely interesting & addictive once a player gets hang of it. The way to play this game is straightforward, eliminate rest of the players on the world map. The main idea is to overwhelm your enemy with power, but the means of doing this are as varied as the players who love the game. It can be done with diplomacy or it can be done with brute force. The crux of the game is to weigh all the possibilities in your head and use percentages to come out with the best possible solution at that pertinent moment.

Players are eliminated when they lose all of their troops on the game board. Players must be skilled in troop deployment and must be aware of the underlying probabilities present in the game. When finished attacking and before passing the turn over to the next player, a player has the option to maneuver any number of armies from a single territory occupied by the player into an adjacent territory occupied by the same player. This is sometimes referred to as a "free move".

The board is a guide of the world separated into six main-lands included 42 domains. Players might just move between adjoining domains, except for couple of regions over water. If an attacker occupies a defender's last territory, the defender is eliminated from the game and the attacker acquires all of the defender's Risk cards.

There are three main phases to a player's turn: getting and placing new armies, attacking, and fortifying. The board can be simplified by turning it into a graph where the territories are the nodes and the lines between nodes are the potential paths that can be taken from territory to territory. One key to victory is control over continents. Players that hold continents at the beginning of a turn get bonus reinforcements in an amount roughly proportional to the size of the continent. Thus, the key positions on the board are the territories on the borders of continents.

The board can be disentangled by transforming it into a diagram where the domains are the hubs and the lines between hubs are the potential ways that can be taken from region to region. One key to triumph is control over main-lands. Players that hold main-lands toward the start of a turn get extra fortifications in a sum generally corresponding to the span of the landmass. In this manner, the key positions on the board are the domains on the fringes of main-lands.

There are two ways to determine the initial territories: Have each player roll a die (Standard Rules). The player that rolled the highest value will choose an open territory and place one soldier in it. Moving clock-wise, each player will select an open territory until all territories are occupied. Once players have claimed all the 42 territories on the board, players place their remaining armies onto territories they already claim in any order they choose.

Second way is to Deal out the deck of cards (Alternate Rules). Entire deck of card is used minus the two Wild cards and then each player needs to place one of their army pieces in each territory according to the cards they are holding. Turns should be taken to do this. The key disadvantage to attacking is that you usually lose armies as you gain territories; and even if you are lucky enough to not lose any armies in your battles, in a sense you become weaker with each territory you win since your armies are now dispersed over a larger number of territories. This gives the opponent more territories to attack with a greater chance of success.

When the sum total of what regions have been guaranteed, players continue to put the rest of their beginning troop assignments one by one in a clockwise manner. A mismatch in army strength is especially valuable early on. This means that you should try to redeem your Risk cards for reinforcements early on, when reinforcements count for more. That mismatch doesn't mean as much later on. The beginning troop distribution per player is subject to the quantity of players taking part in the game.

For a game with such simple rules, Risk can be an intricate, even beautiful game. It is fun, intense and requires skills that will also benefit the player in the real world. Keeping the advice set down here in mind, the best way to learn the game is, like everything else, through experience. 'Risk' boats of numerous exciting versions all over the web. Every version is unique and demands aptitude and luck to be at your forte!
