Checkerboard
A checkerboard (American English) or chequerboard (British English; see spelling differences) is a board of checkered pattern on which checkers (also known as English draughts) is played. Most commonly, it consists of 64 squares (8×8) of alternating dark and light color, typically green and buff (official tournaments), black and red (consumer commercial), or black and white (printed diagrams). An 8×8 checkerboard is used to play many other games, including chess, whereby it is known as a chessboard. Other rectangular square-tiled boards are also often called checkerboards. Games and puzzles using checkerboards Martin Gardner featured puzzles based on checkerboards in his November 1962 Mathematical Games column in Scientific American. A square checkerboard with an alternating pattern is used for games including: * Amazons * Chapayev * Chess and some of its variants (see chessboard) * Czech draughts * Draughts, also known as checkers * Fox games * Frisian draughts * Gounki * In ...

Check (pattern)
Check (also checker, Brit: chequer) is a pattern of modified stripes consisting of crossed horizontal and vertical lines which form squares. The pattern typically contains two colours where a single checker (that is a single square within the check pattern) is surrounded on all four sides by a checker of a different colour. The pattern is commonly placed onto garments and is, in certain social contexts, applied to clothing which is worn to signify cultural or political affiliations. Such is the case with check in ska and on the keffiyeh. The pattern's all-pervasiveness and simple layout has lent to its practical usage in scientific experimentation and observation, optometry, technology (hardware and software), and as a symbol for responders to associate meaning with. Etymology The word is derived from the ancient Persian word ' which means "king" in the Sasanian game of Shatranj; an old form of chess which is played on a squared board of alternating coloured checkers. It is more ...

Checkers
Checkers (American English), also known as draughts (; British English), is a group of strategy board games for two players which involve diagonal moves of uniform game pieces and mandatory captures by jumping over opponent pieces. Checkers is developed from alquerque. The term "checkers" derives from the checkered board which the game is played on, whereas "draughts" derives from the verb "to draw" or "to move". The most popular forms of checkers in Anglophone countries are American checkers (also called English draughts), which is played on an 8×8 checkerboard; Russian draughts, Turkish draughts both on an 8x8 board, and International draughts, played on a 10×10 board – the latter is widely played in many countries worldwide. There are many other variants played on 8×8 boards. Canadian checkers and Singaporean/Malaysian checkers (also locally known as ''dum'') are played on a 12×12 board. American checkers was weakly solved in 2007 by a team of Canadian computer ...

Mathematical Games Column
Over a period of 24 years (January 1957 – December 1980), Martin Gardner wrote 288 consecutive monthly "Mathematical Games" columns for ''Scientific American'' magazine. During the next years, through June 1986, Gardner wrote 9 more columns, bringing his total to 297, as other authors wrote most of the "Mathematical Games" columns. The table below lists Gardner's columns. Twelve of Gardner's columns provided the cover art for that month's magazine, indicated by "over in the table with a hyperlink to the cover. Other articles by Gardner Gardner wrote 5 other articles for ''Scientific American''. His flexagon article in December 1956 was in all but name the first article in the series of ''Mathematical Games'' columns and led directly to the series which began the following month.

Fox Games
Fox games are a category of asymmetric board games for two players, where one player is the fox and tries to eat the geese / sheep, and the opposing player directs the geese/sheep and attempts to trap the fox, or reach a destination on the board. In another variant, ''Fox and Hounds'', the fox merely tries to evade the hounds. There are several versions known: History The game ''Halatafl'' is known from at least as early as the 14th century, and it is mentioned in Grettis saga. It probably originated in Scandinavia, as a variant of Tafl. In fact, Halatafl is still played in Scandinavia with rules similar to Tafl; see below. Edward IV of England is known to have purchased two foxes and 26 hounds to form two sets of ''Marelles'', believed to be Fox and Hounds. As Fox and Geese, the game was a favorite pastime of Queen Victoria. Halatafl ''Halatafl'' means "tail board", in Old Norse, and "tail" presumably refers to a fox's tail. As in Grettis saga, ''rävspelet'' (modern Swed ...

American And British English Spelling Differences
Despite the various List of dialects of English, English dialects spoken from country to country and within different regions of the same country, there are only slight regional variations in English orthography, the two most notable variations being British and American spelling. Many of Comparison of American and British English, the differences between American English, American and British English date back to a time before spelling standards were developed. For instance, some spellings seen as "American" today were once commonly used in Britain, and some spellings seen as "British" were once commonly used in the United States. A "British standard" began to emerge following the 1755 publication of Samuel Johnson's ''A Dictionary of the English Language'', and an "American standard" started following the work of Noah Webster and, in particular, his ''Webster's Dictionary, An American Dictionary of the English Language'', first published in 1828. Webster's efforts at spellin ...

English Draughts
English draughts (British English) or checkers (American English), also called straight checkers or simply draughts, is a form of the strategy board game checkers (or draughts). It is played on an 8×8 checkerboard with 12 pieces per side. The pieces move and capture diagonally forward, until they reach the opposite end of the board, when they are crowned and can thereafter move and capture both backward and forward. As in all forms of draughts, English draughts is played by two opponents, alternating turns on opposite sides of the board. The pieces are traditionally black, red, or white. Enemy pieces are captured by jumping over them. The 8×8 variant of draughts was weakly solved in 2007 by a team of Canadian computer scientists led by Jonathan Schaeffer. From the standard starting position, both players can guarantee a draw with perfect play. Pieces Though pieces are traditionally made of wood, now many are made of plastic, though other materials may be used. Pieces are t ...

Chapayev (game)
Chapayev (russian: игра в Чапаева, translit=igra v Chapayeva, 'game of Chapayev' or 'Chapayev's game') is a board game, a hybrid of checkers (draughts) and gamepiece-impact games like carrom, novuss, and pichenotte, giving it gameplay aspects in common with both billiards and table shuffleboard on a smaller scale, as well as some checkers strategy. It is played throughout the territory of the former USSR. The aim is to knock the opponent's pieces off the board. The game is named after the Russian Civil War hero, Vasily Chapayev. Equipment The game requires a checkerboard and checkers, eight pieces of each colour. Pieces are of small size (smaller than the squares on the board, or the game may be too easy), and usually made of wood. Rules The game is played in several rounds, with two players (or potentially with two teams of players alternating turns or shots during their turn). During the first round, white pieces are placed on the first row, and black on the last ...

Amazons (game)
The Game of the Amazons (in Spanish, ''El Juego de las Amazonas;'' often called Amazons for short) is a two-player abstract strategy game invented in 1988 by Walter Zamkauskas of Argentina.. The game is played by moving pieces and blocking the opponents from squares, and the last player able to move is the winner. It is a member of the territorial game family, a distant relative of Go and chess. The Game of the Amazons is played on a 10x10 chessboard (or an international checkerboard). Some players prefer to use a monochromatic board. The two players are White and Black; each player has four ''amazons'' (not to be confused with the amazon fairy chess piece), which start on the board in the configuration shown at right. A supply of markers (checkers, poker chips, etc.) is also required. Rules White moves first, and the players alternate moves thereafter. Each move consists of two parts. First, one moves one of one's own amazons one or more empty squares in a straight line (o ...

Chess
Chess is a board game for two players, called White and Black, each controlling an army of chess pieces in their color, with the objective to checkmate the opponent's king. It is sometimes called international chess or Western chess to distinguish it from related games, such as xiangqi (Chinese chess) and shogi (Japanese chess). The recorded history of chess goes back at least to the emergence of a similar game, chaturanga, in seventh-century India. The rules of chess as we know them today emerged in Europe at the end of the 15th century, with standardization and universal acceptance by the end of the 19th century. Today, chess is one of the world's most popular games, played by millions of people worldwide. Chess is an abstract strategy game that involves no hidden information and no use of dice or cards. It is played on a chessboard with 64 squares arranged in an eight-by-eight grid. At the start, each player controls sixteen pieces: one king, one queen, two rooks, t ...

Lines Of Action
Lines of Action (or LOA) is an abstract strategy board game for two players invented by Claude Soucie. The objective is to connect all of one's pieces into a single group. The game was recommended by the Spiel des Jahres in 1988. Rules Goal The object of the game is to bring all of one's pieces together into a contiguous body so that they are connected vertically, horizontally or diagonally ( 8-connectivity). Movement summary * Players alternate moves, with Black having the first move. * Pieces move horizontally, vertically, or diagonally. * A piece moves exactly as many spaces as there are pieces (both friendly and enemy) on the line in which it is moving. For example, Black may open with c8-c6. Black's piece moves two. Movement diagrams A piece may not jump over an enemy piece. Thus in the diagram below, White cannot play a6-d6, even though there are three pieces in row 6. White might instead play a6-c4, moving two spaces because there are two pieces in the diagonal (a6-f1) ...

The opponent playing the dark pieces will start the game by making the first move. One difference from the rules of English checkers is that a piece may capture both forward and backward. A player must capture an opponent's checker when possible (both forward and backward), but if two possibilities exist, the player may choose the sequence (even if ...
