Draughts
Checkers (American English), also known as draughts (; Commonwealth English), is a group of strategy board games for two players which involve forward movements 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 and Armenian draughts, all of them on an 8×8 board; and international draughts, played on a 10×10 board – with the latter widely played in many countries worldwide. There are many other variants played on 8×8 boards. Canadian checkers and Malaysian/Singaporean checkers (also locally known as dam) are played on a 12×12 board. American checkers was weakly ...

International Draughts
International draughts (also called international checkers or Polish draughts) is a Abstract strategy, strategy board game for two players, one of the variants of draughts. The gameboard comprises 10×10 squares in alternating dark and light colours, of which only the 50 dark squares are used. Each player has 20 pieces, light for one player and dark for the other, at opposite sides of the board. In conventional diagrams, the board is displayed with the light pieces at the bottom; in this orientation, the lower-left corner square must be dark. History According to Dutch Draughts historians, draughts historian Arie van der Stoep, it is unknown where the 10×10 square draughts board first came into use. In the Netherlands, the board was probably used from 1550, and the number of pieces was extended to 2×20 between 1650 and 1700. The name "Polish draughts" was probably following a Dutch convention of the time that "unnatural" ideas were considered "Polish". Rules The general rule ...

English Draughts
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 typicall ...

Turkish Draughts
Turkish draughts (Turkish: Dama)(Armenian: շաշկի, տամա)(Arabic: دامە)(Kurmanji: Dame) is a variant of draughts (checkers) played in Turkey, Greece, Egypt, Kuwait, Lebanon, Syria, Jordan, and several other locations around the Mediterranean Sea and Middle East. Rules On an 8×8 board, 16 ' are lined up on each side, in two rows. The back rows are vacant. A traditional Turkish draughts is mono-coloured. White moves first. Men move orthogonally forwards or sideways one square, capturing by means of a jump; they cannot move or capture backwards or diagonally. When a man reaches the back row, it promotes to a ''king''. Kings can move any number of empty squares orthogonally forwards, backwards or sideways. A king captures by jumping over a single piece any number of empty squares away, landing on any open square beyond the captured piece along a straight line. If a jump is available it must be taken. If there is more than one way to jump, the one capturing the most num ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russian Draughts
Russian draughts (also known as Shashki or Russian shashki) is a variant of draughts (checkers) played in Russia and some parts of the former USSR, as well as parts of Eastern Europe and Israel. Rules As in all draughts variants, Russian draughts is played by two people, on opposite sides of a playing board, alternating moves. One player has dark pieces, and the other has light pieces. Pieces move diagonally and pieces of the opponent are captured by jumping over them. The rules of this variant of draughts are: * Board. Played on an 8×8 board with alternating dark and light squares. The left square of the first Rank (chess), rank should be dark. * Starting position. Each player starts with 12 pieces on the three rows closest to their own side. The row closest to each player is called the "crownhead" or "kings row". Usually, the colors of the pieces are black and white, but possible use other colors (one dark and other light). The player with white pieces (lighter color) moves f ...

Armenian Draughts
Armenian draughts, or Tama, is a variant of draughts (or checkers) played in Armenia. The rules are similar to Dama. Armenian draughts, however, allows for diagonal movement. Rules On an 8×8 board, 16 men are lined up on each side in two rows, skipping the first and last row. From a player's point of view, the second and third rows are filled with men of his own color, and the sixth and seventh rows are filled with the opponent's men. Players alternate turns with each making one move per turn. Pieces initially consist of men only. When reaching the opposite side of the board, men are "crowned" to pieces called kings. A man can move forwards, straight ahead or diagonally, or sideways to an orthogonally adjacent field if that field is empty. Kings may move in all directions (up, down, left, right, or diagonally), as long as the path is clear of pieces. In other words, the king moves like a Chess queen. If a man is orthogonally adjacent to an opponent's man, and there is an emp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadian Checkers
Canadian checkers (or Canadian draughts) is a variant of the strategy board game draughts. It is one of the largest draughts games, played on a 12×12 checkered board with 30 game pieces per player. History The game was invented by the French settlers of Quebec, Canada; it was named ''Grand jeu de dames''. It is unknown when the game was first played in Canada. The ''huff'' rule was dropped in 1880 after a dispute developed during the Canadian championship match. The idea of an increased-size international draughts game is older still; boards with 12×12 squares were on sale in London in 1805.

Checkerboard
A checkerboard (American English) or chequerboard (British English) is a game board of check (pattern), 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 (colour), 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. In The Netherlands, however, a ''dambord'' (checker board) has 10 rows and 10 columns for 100 squares in total (see article International draughts). 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chess
Chess is a board game for two players. It is an abstract strategy game that involves Perfect information, no hidden information and no elements of game of chance, chance. It is played on a square chessboard, board consisting of 64 squares arranged in an 8×8 grid. The players, referred to as White and Black in chess, "White" and "Black", each control sixteen Chess piece, pieces: one king (chess), king, one queen (chess), queen, two rook (chess), rooks, two bishop (chess), bishops, two knight (chess), knights, and eight pawn (chess), pawns, with each type of piece having a different pattern of movement. An enemy piece may be captured (removed from the board) by moving one's own piece onto the square it occupies. The object of the game is to "checkmate" (threaten with inescapable capture) the enemy king. There are also several ways a game can end in a draw (chess), draw. The recorded history of chess goes back to at least the emergence of chaturanga—also thought to be an ancesto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solved Game
A solved game is a game whose outcome (win, lose or tie (draw), draw) can be correctly predicted from any position, assuming that both players play perfectly. This concept is usually applied to abstract strategy games, and especially to games with full information and no element of chance; solving such a game may use combinatorial game theory or computer assistance. Overview A two-player game can be solved on several levels: Ultra-weak solution : Prove whether the first player will win, lose or draw from the initial position, given perfect play on both sides . This can be a non-constructive proof (possibly involving a strategy-stealing argument) that need not actually determine any details of the perfect play. Weak solution : Provide one algorithm for each of the two players, such that the player using it can achieve at least the optimal outcome, regardless of the opponent's moves, from the start of the game, using reasonable computational resources. Strong solution : Provide an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malaysian/Singaporean Checkers
Malaysian checkers or Singaporean checkers, is a variant of the board game of draughts played primarily in Malaysia and Singapore, especially among the elder men. Similar to the Canadian checkers, it is played on a 12x12 checkered board. The game can also be played on a 8x8 board if a 12x12 board is unavailable. However, it is distinct from Checkers and Canadian Checkers in terms of its additional rules. Popular alternative names used locally for this game include Dum and Dam. Game rules Malaysian/Singaporean checkers follows the same rules as international draughts, with exceptions being pieces not able to move backwards (towards the player), the requirement to forfeit a capturing piece if the player fails to or wishes not to capture any enemy piece(s) with it, and a larger gameboard (12×12 squares instead of 10×10), and more checkers per player (30 instead of 20). The starting setup is shown in the diagram. Starting position * The game is played on a board of 12×12 alte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
