These traditional variants of checkers have rules similar to International Draughts, in which pieces are allowed to capture backwards. Dames (Kings) are "long" (i.e., can slide and jump any number of squares.). Game logic derives from Ed van Zon's HexDame and from Karl Scherer's Russian checkers. Although there already exists a Zillions standard implementation of Pool checkers, etc., it was necessary to create it anew, because all Zillions's implementations with "long Dames" (or "long Kings") are defective. (The Dame will erroneously continue a finished capture sequence in case two enemy pieces are positioned on the same diagonal, and the Dame captures from between them. Moreover, the Dame capture works incorrectly in Pool checkers, German checkers, and Russian checkers. In some positions it refrains from making the full capturing sequence.)

International Draughts (Polish draughts) is played on a 10x10 board with 20 pieces per player. The object is to capture all your opponent's men by jumping over them, or stalemate the opponent so he has no moves. A Man can move forward, by sliding diagonally to an adjacent empty square. It may also jump over an enemy piece in any direction to a vacant square on the other side. Jumping over a piece captures it. Capturing is mandatory, and you must keep jumping and capturing as long as it is possible. You must even choose beforehand the series of jumps that captures the most men. When your Man reaches the other end of the board, it becomes a Dame and can then move and capture forwards and backwards over any distance. It also jumps to capture, but only one Man at a time. A Dame must also choose the line that makes the most captures.

Canadian Checkers (or Canadian draughts) uses the same rules as International draughts, but the game is played on a 12x12 board with 30 pieces per player. Canadian Checkers was invented by the French settlers of Quebec, Canada. It was originally named Grand jeu de dames. It is unknown when the game was first played in Canada. The idea of an increased-size international draughts game is older still; boards with 12x12 squares were on sale in London in 1805 (cf. Wikipedia).

Sri Lankan Checkers (or Lankesian draughts) is the same as Canadian Checkers, except that the board is mirrored.

Dumm (or "long draughts") is played in South Africa. Dumm uses the same rules as Dame (International Draughts) but is played on a 14x14 board with 42 pieces per player. It is still played in Cape Town. (However, the old huff rule is not implemented here.)

Damii (Ghanaian draughts) is similar to International Draughts (board size 10x10). However, although capture is mandatory, it is not mandatory to capture the longest line (i.e. it is not necessary to choose the series of jumps that captures the most men). In Ghana, players use the huff rule, but this is not implemented here. Play is very fast-paced.

Brazilian Checkers (Minor Polish draughts) is similar to Dame (International Draughts), but played on an 8x8 board with 12 pieces per player. If a Man makes an intermediate landing on a promotion square and can continue capturing, it is not promoted. This variant was known already in the 16th century, and possibly even earlier. It was a popular board game in Holland, especially in Amsterdam.

Philippine Checkers is the same as Brazilian checkers except that the board is mirrored. Players from Luzon, Panay, and part of Mindanao, play on the mirrored board. However, according to the World Dama Federation, it should be played on the regular board (same as Brazilian checkers.)

Pool Checkers is similar to International Draughts, but is played on an 8x8 board. Although capture is mandatory, it is not mandatory to capture the longest line (i.e. it is not necessary to choose the series of jumps that captures the most men). It is the same as Northern German checkers, which is played on a mirrored board. The first book covering German Draughts was the 155-page folio volume "Die unterschiedlichen Spiel- und Vorstellungen des weltberühmten Damspiels", which was published around 1700 in Nuremberg by Johann Wolfgang Schmidt (cf. checkers.wikia.com). In America, where it acquired the name Pool checkers, this variant has its own organization; the American Pool Checkers Association (APCA).

Jamaican Checkers (North German Checkers) is the same as Pool checkers. The only difference is the mirrored board. Jamaica is an island country situated in the Caribbean Sea. In 2013 the population was 2.715 million. A German population was established in Jamaica in the 1830's and some German words have entered the Jamaican vernacular (cf. Wikipedia).

Russian Checkers (Draughts-64, "Russkie Shashki") is the same as Pool Checkers, except that a Man is promoted to Dame during a capture sequence, if it makes an intermediate landing on a promotion square. Although capture is mandatory, it is not mandatory to capture the longest line. This variant is played in Russia, former Eastern Bloc countries, and in Israel. The International Draughts Federation (IDF) has adopted the name "Draughts-64".

Note! I also introduce variants with a special rule that serves to reduce drawishness: the Dame must stop on the first vacant square after the last captured piece, if and only if that piece is also a Dame. Thus, two Dames will always win against one Dame. I believe this is a significant improvement, especially for the 8x8 variants. This rule is fetched from "Killer draughts", which is also included.
