3-In-1 Checkers is a fun 1-player online version of the well-known Checkers board game (also called Draughts). You play against the computer, and have to remove all of your opponent’s checkers pieces by jumping over them and landing on a similar colored square to the one that you jumped from. Unlike most online checkers games this version has some new playing modes which add a cool twist to the classic strategy game. Pit your wits against varying levels of computer-controlled opponents, and try your best to come out on top.

Your strategic planning abilities will be exercised, as you have to carefully plan your moves in advance. Surprisingly, your quick reactions will also be tested, as some of the game modes require quick-fire moves and fast decision making. Have you got the strategic know-how to be crowned the Checkers King (or Queen)? See if you can ‘sweep the board’, and defeat the computer. Good luck!

International Draughts

How to Play: There are three different game modes to choose from – Standard, Giveaway and Extreme. Before you start a game, you can adjust the difficulty level of the computer by moving the Difficulty Bar on the right hand side of the main menu screen. In Standard Mode, you play a normal game of checkers, taking turns against the computer. Your goal is to ‘jump’ all of his pieces until there are none remaining on the board. You can only capture one of your opponent’s pieces by ‘jumping’ over it and landing on a similar colored square to the one that you jumped from.

You control the Red Checkers, the computer controls the Whites. Move your pieces by clicking and dragging them using your computer mouse or touchpad. If one of your pieces makes it to the opposite end of the board, it becomes a King. Until then, the piece can only move forwards. Once it becomes a King, the piece can move forwards and backwards as you wish. Keep jumping your opponent’s pieces until none remain to win the game. In Giveaway Mode, the objective is the opposite – the player who gets rid of all of his pieces first wins the game. In Extreme Mode, the rules are different again. There are no turns, you can move as many times as you like in a row – if you are fast enough.

Draughts (British English) or checkers[1] (American English) is a group of strategyboard games for two players which involve diagonal moves of uniform game pieces and mandatory captures by jumping over opponent pieces. Draughts developed from alquerque.[2] The name derives from the verb to draw or to move.[3]

The most popular forms are English draughts, also called American checkers, played on an 8×8 checkerboard; Russian draughts, also played on an 8×8, and international draughts, played on a 10×10 board. 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.

The 8×8 variant of draughts was weakly solved in 2007 by the team of Canadian computer scientist Jonathan Schaeffer. From the standard starting position, both players can guarantee a draw with perfect play.

General rules [edit]

Draughts is played by two opponents, on opposite sides of the gameboard. One player has the dark pieces; the other has the light pieces. Players alternate turns. A player may not move an opponent's piece. A move consists of moving a piece diagonally to an adjacent unoccupied square. If the adjacent square contains an opponent's piece, and the square immediately beyond it is vacant, the piece may be captured (and removed from the game) by jumping over it.

Only the dark squares of the checkered board are used. A piece may move only diagonally into an unoccupied square. When presented, capturing is mandatory in most official rules, although some rule variations make capturing optional.[4] In almost all variants, the player without pieces remaining, or who cannot move due to being blocked, loses the game.

Men[edit]

Uncrowned pieces (men) move one step diagonally forwards, and capture an opponent's piece by moving two consecutive steps in the same line, jumping over the piece on the first step. Multiple enemy pieces can be captured in a single turn provided this is done by successive jumps made by a single piece; the jumps do not need to be in the same line and may 'zigzag' (change diagonal direction). In English draughts men can jump only forwards; in international draughts and Russian draughts men can jump both forwards and backwards.

Kings [edit]

A game in international draughts, featuring a flying king

When a man reaches the kings row (also called crownhead, the farthest row forward), it becomes a king, and is marked by placing an additional piece on top of the first man, and acquires additional powers including the ability to move backwards and (in variants where they cannot already do so) capture backwards. Like men, a king can make successive jumps in a single turn provided that each jump captures an enemy man or king.

In international draughts, kings (also called flying kings) move any distance along unblocked diagonals, and may capture an opposing man any distance away by jumping to any of the unoccupied squares immediately beyond it. Because jumped pieces remain on the board until the turn is complete, it is possible to reach a position in a multi-jump move where the flying king is blocked from capturing further by a piece already jumped.

Flying kings are not used in English draughts; a king's only advantage over a man is the ability to move and capture backwards as well as forwards.

Naming[edit]

In most non-English languages (except those that acquired the game from English speakers), draughts is called dame, dames, damas, or a similar term that refers to ladies. The pieces are usually called men, stones, 'peón' (pawn) or a similar term; men promoted to kings are called dames or ladies. In these languages, the queen in chess or in card games is usually called by the same term as the kings in draughts. A case in point includes the Greek terminology, in which draughts is called 'ντάμα' (dama), which is also one term for the queen in chess.

Russian Column draughts[edit]

Column draughts (Russian towers) - a kind of draughts, known in Russia since the beginning of the XIX century, in which the game is played according to the usual rules of draughts, but with the difference that the beaten draught is not removed from the playing field, and is captured under the beating figure (draught or tower).
The resulting towers move around the Board as a whole, 'obeying' the upper draught. When taking the tower, only the upper draught is removed from it. If on the top there is a draught of other color than removed as a result of fight, the tower becomes a tower of the rival. Rules of moves of draughts and kings correspond to the rules of Russian draughts.

International draughts (or Polish draughts)10×1020YesWhiteA sequence must capture the maximum possible number of pieces.Pieces promote only when ending their move on the final rank, not when passing through it. It is mainly played in the Netherlands, Suriname, France, Belgium, some eastern European countries, some parts of Africa, some parts of the former USSR, and other European countries.
Ghanaian draughts (or damii)10×1020No[5]WhiteAny sequence may be chosen, as long as all possible captures are made. Overlooking a king's capture opportunity leads to forfeiture of the king.Played in Ghana. Having only a single piece remaining (man or king) loses the game.
Frisian draughts [nl]10×1020YesWhiteA sequence of capture must give the maximum 'value' to the capture, and a king (called a wolf) has a value of less than two men but more than one man. If a sequence with a capturing wolf and a sequence with a capturing man have the same value, the wolf must capture. The main difference with the other games is that the captures can be made diagonally, but also straight forwards and sideways.Played primarily in Friesland (Dutch province) historically, but in the last decade spreading rapidly over Europe (e.g. the Netherlands, Belgium, Italy, Czech Republic, Ukraine and Russia) and Africa, as a result of a number of recent international tournaments and the availability of an iOS and Android app 'Frisian Draughts'.
Canadian checkers12×1230YesWhiteA sequence must capture the maximum possible number of pieces.International rules on a 12×12 board. Played mainly in Canada.
Brazilian draughts (or derecha)8×812YesWhiteA sequence must capture the maximum possible number of pieces.Played in Brazil. The rules come from international draughts, but board size and number of pieces come from English draughts.

In the Philippines, it is known as derecha and is played on a mirrored board, often replaced by a crossed lined board (only diagonals are represented).

Pool checkers8×812YesBlackAny sequence may be chosen, as long as all possible captures are made.Also called Spanish Pool checkers. It is mainly played in the southeastern United States; traditional among African American players. A man reaching the kings row is promoted only if he does not have additional backwards jumps (as in international draughts).[1][permanent dead link][2]

In an ending with three kings versus one king, the player with three kings must win in thirteen moves or the game is a draw.

Jamaican draughts/checkers8×812YesBlackAny sequence may be chosen, as long as all possible captures are made.Similar to Pool checkers with the exception of the main diagonal on the right instead of the left. A man reaching the kings row is promoted only if he does not have additional backwards jumps (as in international draughts).

In an ending with three kings versus one king, the player with three kings must win in thirteen moves or the game is a draw.

Russian draughts8×812YesWhiteAny sequence may be chosen, as long as all possible captures are made.Also called shashki or Russian shashki checkers. It is mainly played in the former USSR and in Israel. Rules are similar to international draughts, except:
  • a man that enters the kings row during a jump and can continue to jump backwards, jumps backwards as a king, not as a man;
  • choosing a sequence that captures the maximum possible number of pieces is not required.

There is also a 10×8 board variant (with two additional columns labelled i and k) and the give-away variant Poddavki. There are official championships for shashki and its variants.

Mozambican draughts/checkers8×812NoWhiteA sequence must capture the maximum possible number of pieces. Although, a king has the weight of two pieces, this means with two captures, one of a king and one of piece you must choose the king; two captures, one of a king and one of two pieces, you can choose; two captures with one of a king and one of three pieces you choose the three pieces; two captures, one of two kings and one of three pieces, you choose the kings...Also called 'Dama' or 'Damas'. It is played along all of the region of Mozambique. In an ending with three kings versus one king, the player with three kings must win in twelve moves or the game is a draw.

Malaysian/Singaporean checkers12×1230YesNot fixedCaptures are mandatory. Failing to capture results in forfeiture of that piece (huffing).Mainly played in Malaysia, Singapore, and the region nearby. Also known locally as 'Black–White Chess'. Sometimes it is played on an 8×8 board when a 12×12 board is unavailable; a 10×10 board is rare in this region.
Czech draughts8×812YesWhiteIf there are sequences of captures with either a man or a king, the king must be chosen. After that, any sequence may be chosen, as long as all possible captures are made.This variant is from the family of the Spanish game.
Hungarian Highlander (Slovak) draughts8×88WhiteAll pieces are long-range. Jumping is mandatory after first move of the rook. Any sequence may be chosen, as long as all possible captures are made.The uppermost symbol of the cube determines its value, which is decreased after being jumped. Having only one piece remaining loses the game.

NoWhiteA sequence must capture the maximum possible number of pieces, and the maximum possible number of kings from all such sequences. If both sequences capture the same number of pieces and one is with a king, the king must do.[3]The rules are similar to the Spanish game, but the king, when it captures, must stop after the captured piece, and may begin a new capture movement from there.

With this rule, there is no draw with two pieces versus one.

Thai draughts8×88YesBlackAny sequence may be chosen, as long as all possible captures are made.During a capturing move, pieces are removed immediately after capture. Kings stop on the square directly behind the piece captured and must continue capturing from there, if possible, even in the direction where they have come from.
German draughts (or Dame)8×812YesBlackAny sequence may be chosen, as long as all possible captures are made.Kings stop on the square directly behind the piece captured and must continue capturing from there as long as possible.
Turkish draughts8×816N/AWhiteA sequence must capture the maximum possible number of pieces.Also known as Dama. All 64 squares are used, dark and light. Men move straight forwards or sideways, instead of diagonally. When a man reaches the last row, it is promoted to a flying king (Dama), which moves like a rook (or a queen in the Armenian variant). The pieces start on the second and third rows.

It is played in Turkey, Kuwait, Israel, Lebanon, Syria, Jordan, Greece, and several other locations in the Middle East, as well as in the same locations as Russian checkers. There are several variants in these countries, with the Armenian variant (called tama) allowing also forward-diagonal movement of men.

Myanmar draughts8×812WhiteA sequence must capture the maximum possible number of pieces.Players agree before starting the game between 'Must Capture' or 'Free Capture'. In the 'Must Capture' type of game, a man that fails to capture is forfeited (huffed). In the 'Free Capture' game, capturing is optional.
Tanzanian draughts8×812YesNot fixedAny sequence may be chosen, as long as all possible captures are made.Captures are mandatory. When either a king or a man can capture, there is no priority.

Starting position for international draughts which is played on a 10×10 board

The World Championship in English draughts began in 1840. The winners in men's have been from the United Kingdom, United States, Barbados, and most recently Italy (3-Move division). The women's championship in English draughts started in 1993. The women's winners have been from Ireland, Turkmenistan, and Ukraine.

Board Game Similar To Draughts

The World Championship in international draughts began in 1885 in France, and since 1948 has been organized by the World Draughts Federation (FMJD, Fédération Mondiale du Jeu de Dames). It occurs every two years. In even years following the tournament, the World Title match takes place. The men's championship has had winners from the Netherlands, Canada, the Soviet Union, Senegal, Latvia, and Russia. The first Women's World Championship was held in 1973. The World Junior Championship has been played since 1971. European Championships have been held since 1965 (men's) and 2000 (women's).

Other official World Championships began as follows: Brazilian draughts, in 1985; Russian draughts, in 1993; Turkish draughts, in 2014.

Invented variants[edit]

  • Blue and Gray: On a 9×9 board, each side has 17 guard pieces that move and jump in any direction, to escort a captain piece which races to the center of the board to win.
  • Cheskers: A variant invented by Solomon Golomb. Each player begins with a bishop and a camel (which jumps with coordinates (3,1) rather than (2,1) so as to stay on the black squares), and men reaching the back rank promote to a bishop, camel, or king.
  • Damath: A variant utilizing math principles and numbered chips popular in the Philippines.
  • Dameo: A variant played on an 8×8 board, move and capture rules are similar to those of Armenian draughts. A special 'sliding' move is used for moving a line of checkers similar to the movement rule in Epaminondas. By Christian Freeling (2000).
  • Hexdame: A literal adaptation of international draughts to a hexagonal gameboard. By Christian Freeling (1979).
  • Lasca: A checkers variant on a 7×7 board, with 25 fields used. Jumped pieces are placed under the jumper, so that towers are built. Only the top piece of a jumped tower is captured. This variant was invented by World Chess ChampionEmanuel Lasker.
  • Philosophy shogi checkers: A variant on a 9×9 board, game ending with capturing opponent's king. Invented by Inoue Enryō and described in Japanese book in 1890.
  • Suicide checkers (also called Anti-Checkers, Giveaway Checkers or Losing Draughts): A variant where the objective of each player is to lose all of their pieces.
  • Tiers: A complex variant which allows players to upgrade their pieces beyond kings.
  • Vigman's draughts: Each player has 24 pieces (two full sets) – one on the light squares, a second set on dark squares. Each player plays two games simultaneously: one on light squares, the other on dark squares. The total result is the sum of results for both games.

Games sometimes confused with draughts variants[edit]

  • Halma: A game in which pieces move in any direction and jump over any other piece (but no captures), friend or enemy, and players try to move them all into an opposite corner.
  • Chinese Checkers: Based on Halma, but uses a star-shaped board divided into equilateral triangles.
  • Konane: 'Hawaiian checkers'.

History[edit]

Ancient games[edit]

A similar game has been played for thousands of years.[3]A board resembling a draughts board was found in Ur dating from 3000 BC.[6] In the British Museum are specimens of ancient Egyptian checkerboards, found with their pieces in burial chambers, and the game was played by Queen Hatasu.[3][7]Plato mentioned a game, πεττεία or petteia, as being of Egyptian origin,[7] and Homer also mentions it.[7] The method of capture was placing two pieces on either side of the opponent's piece. It was said to have been played during the Trojan War.[8][9] The Romans played a derivation of petteia called latrunculi, or the game of the Little Soldiers. The pieces, and sporadically the game itself, were called calculi (pebbles).[7][10]

Alquerque[edit]

Alquerque board and setup

An Arabic game called Quirkat or al-qirq, with similar play to modern draughts, was played on a 5×5 board. It is mentioned in the 10th-century work Kitab al-Aghani.[6] Al qirq was also the name for the game that is now called nine men's morris.[11] Al qirq was brought to Spain by the Moors,[12] where it became known as Alquerque, the Spanish derivation of the Arabic name. The rules are given in the 13th-century book Libro de los juegos.[6] In about 1100, probably in the south of France, the game of Alquerque was adapted using backgammon pieces on a chessboard.[13]Each piece was called a 'fers', the same name as the chess queen, as the move of the two pieces was the same at the time.[14]

Crowning[edit]

Men in medieval clothing playing draughts

The rule of crowning was used by the 13th century, as it is mentioned in the Philip Mouskat's Chronique in 1243[6] when the game was known as Fierges, the name used for the chess queen (derived from the Persian ferz, meaning royal counsellor or vizier). The pieces became known as 'dames' when that name was also adopted for the chess queen.[14] The rule forcing players to take whenever possible was introduced in France in around 1535, at which point the game became known as Jeu forcé, identical to modern English draughts.[6][13] The game without forced capture became known as Le jeu plaisant de dames, the precursor of international draughts.

The 18th-century English author Samuel Johnson wrote a foreword to a 1756 book about draughts by William Payne, the earliest book in English about the game.[7]

Computer draughts[edit]

English draughts (American 8×8 checkers) has been the arena for several notable advances in game artificial intelligence. In the 1950s, Arthur Samuel created one of the first board game-playing programs of any kind. More recently, in 2007 scientists at the University of Alberta[15] developed their 'Chinook' program to the point where it is unbeatable. A brute force approach that took hundreds of computers working nearly two decades was used to solve the game,[16] showing that a game of draughts will always end in a draw if neither player makes a mistake.[17][18] The solution is for the draughts variation called go-as-you-please (GAYP) checkers and not for the variation called three-move restriction checkers. As of December 2007, this makes English draughts the most complex game ever solved.

Computational complexity[edit]

Generalized Checkers is played on an N × N board.

It is PSPACE-hard to determine whether a specified player has a winning strategy. And if a polynomial bound is placed on the number of moves that are allowed in between jumps (which is a reasonable generalization of the drawing rule in standard Checkers), then the problem is in PSPACE, thus it is PSPACE-complete.[19] However, without this bound, Checkers is EXPTIME-complete.[20]

However, other problems have only polynomial complexity:[19]

  • Can one player remove all the other player's pieces in one move (by several jumps)?
  • Can one player king a piece in one move?
