Diagonal draughts on larger board -international (Polish) draughts, soviet checkers, Canadian draughts, Frisian draughts, Ghanaian draughts, Malaysian draughts

On Bonaludo I already wrote about 8×8 draughts variants and about three games from orthogonal draughts family. Every time I mentione draughts is not one game. It is a group of games with some common features. So far I described here you only games played on a 64-square board, although with very different rules. Now it’s time to present games on larger boards with 80 fields (8×10), 100 fields (10×10) and even 144 fields (12×12).

Draughts (checkers) on larger boards can use same rules as games on  8×8 board. Increasing the board is always connected with increasing the number of pieces. This increases the complexity and duration of the game, makes it less schematic and less predictable. For this reason draughts on larger board are often games played on tournaments, treated as a serious mind sports such as chess, go (which does not mean that traditional 64-square checkers are “less serious”).

I will describe few games on the larger boards, but as a Pole I must particularly single out Polish draughts, also known as international draughts. In my personal opinion this is the most beautiful variant of draughts.

Polish draughts (international draughts/checkers)

It’s funny but Polish draughts are not very popular in Poland. We call them “Polish” probably because they were invented by a Pole.

Polish draughts are also called international draughts or international checkers. They became a real mind sport relatively early. The first world championship was held in France in 1885 (won by Alfred Dassaut). Initially, the world champions were mainly French, but later champions were representatives of the Soviet Union, the Netherlands and Russia (after the collapse of the USSR). The current world champion is a Russian Aleksandr Grigoriev. Well … we all know that the Russians are serious about mind sports.

Nowadays world championships are held under the auspices of the World Draughts Federation (FMJD – Fédération Mondiale du Jeu de Dames). This organization promotes mainly International draughts but also has a sections of Russian, Brazilian, English and Turkish draughts.  FMJD has more than 50 national federation members.

In the future I’ll write a more extensive article on polish draughts. Now I will confine myself to a brief presentation of the rules.

Rules of the game

The game is played on the dark fields of the chequered 100-sqare board (10×10 board). Thera are 20 white and 20 black pieces set on the first 4 rows on the side of each player. The board is arranged in such manner that the lower left corner is dark.

The board and the initial setting of pieces is shown on the picture below.


This game uses so-called international rules, just as in Brazilian draughts. Here are the rules.

  • White moves first.
  • Ordinary pieces (men) move one space diagonally forward (with the exception of capturings)
  • Capturing is made by “jumping” – moving two consecutive steps in the same line, jumping over the piece on the first step. Multiple opposing pieces may be captured in a single turn if this is done by successive jumps made by a single piece.
  • Captures may be made diagonally forwards and backwards.
  • Capturing is absolutely mandatory. If you missed a capture, you have to undo your move and make move consistent with game rules.
  • If a player has several capture options, it is compulsory to capture the maximum amount of the opponent´s pieces.
  • A piece reaching the last row becomes King. We say it is crowned.
  • A king moves any number of squares diagonally forwards or backwards. After completion of the capturing King can land on any field behind the captured piece.
  • Piece is crowned (it becomes King) only if it finishes his move in the last row. In the situation depicted on the diagram below, man does not become King, since the last beating will “bounce” him back from the last line (see the image below).

International draughts – capturing without crowning.

International (Polish) draughts are great and extremely addictive. Despite the relatively simple rules the game leads to very complex and surprising positions (thanks to the increased board). As I said, I in future I’ll write a more extensive articles on Polish draughts.

Soviet checkers (80-square draughts or sovietskiye shashki)

Soviet Checkers is probably the only variant of checkers played on a rectangular board. It was invented by a man named Nikolai Spantsireti around 1930. V. N. Russo mentioned about this game in his book.

Soviet Checkers is nothing but Russian checkers (shashki) on the increased board (8×10 instead of 8×8). The number of pieces is increased so at start there are only two unoccupied rows of fields. To play you need 15 white pieces and 15 black.

Initial setting is shown on the image below.


The rectangular shape of the board creates an interesting situation. There is no main diagonal line in this game, which normally has big strategic importance in draughts games.

As already mentioned, the game is played according to the russian rules. They are nearly the same as the international rules with two exceptions.

  • It’s not compulsory to capture the maximum amount of the opponent’s pieces. The player chooses any sequence.
  • Man is crowned just after reaching the last row. If a piece reached the last row during a capture move, it may continue this move as a king – he is  inmediately crowned and then jumps backwards.

Canadian draughts/Canadian checkers

Canadian checkers is game played on a huge board with 144 fields (12×12). The idea of playing on such a large board is known from the beginning of the XIX century. Invention of canadian checkers is attributed to the French settlers of Quebec (Canadian province).

Rules of the game are the same as international (polish) draughts. That’s why some people call this game “major polish draughts”.

It is also a serious mind sport promoted by association from Quebec- Association Québécoise des joueurs de dames (AQJD).

There is no need to explain the rules of the game, since they are identical to those described above for international checkers. I will only mention that the game is played on the dark fields of the 12×12 board. The board is arranged in such manner that the lower left corner is dark.

The game is played with 30 white and 30 black pieces. At start pieces are set just like in most draughts games – there are  only two rows of free fields between the “fighting armies”. This is shown on the image below.


Frisian draughts

Friesland or Frisia is a province in Netherlands that has its own culture, its own language and a special mind sport – Frisian draughts. This game has been known for over 400 years and its fans think that development of international (Polish) draughts was driven by Frisian draughts. These two games vary considerably, but they use same board and the same initial setting of pieces.

Perhaps in 2018 first official Frisian Draughts World Championships will be held. Aleksandr Grigoriev – the current world champion in international draughts – already tried to play this game. Who knows? Maybe this sport is able to gain big popularity? At this moment you can find information about  World Championships on Frisiandraughts.com, and on this site you can also find an e-book on the rules and strategies.

Let’s move on to describe the rules of the game. As already mentioned, the board, the pieces and the initial setting are the same as in Polish draughts. There is a 10×10 board and 20 men on each side.


What is special in Frisian draughts is a capturing. Men can move only one square diagonally forward, but can capture (shot)  diagonally, vertically or horizontally.

Diagonal capture (diagonal shot) looks just as in the other draughts games. You must jump over the captured piece diagonally and land on the next free field behind it.


There is also horizontal and vertical capture in Frisian draughts. To make it you must jump over a piece located on the next dark field in the horizontal or vertical line and you must land on the next free dark field.

In other words you can make a shot when three consecutive dark squares (regardless of direction) are occupied as follows: your own man – enemy man – empty square. Remember that game is played only on dark fields.

Pictures below show the vertical capture (on the left) and horizontal capture (on the right).


In Frisian draughts, just like in all draughts games, captures may be combined so it’s sometimes possible to jump several pieces in one move. You can change direction of jumps so in practice you can make quite complex shots comprising vertical, horizontal and diagonal jumps.

An example of such a combined shot is shown on the picture below.


A man reaching the last row becomes a king. We say it is crowned. A king moves any number of squares diagonally forwards or backwards, just like in international draughts.


King may make diagonal, vertical and horizontal captures. King’s shots may be made “from a distance” – no matter how many fields is between King and captured piece. In other words position must be king-enemy piece-empty square or king-unoccupied square(s)-enemy piece-empty square.

A king can land on any field behind the captured piece.

The image below shows the possibility of dual capture by a King, using the landing on the second field behind the first captured man. Diagonal capture is followed by a horizontal capture.


Capturing is always mandatory, as in all draughts games.

Pieces are removed from the board after completion the capture (shot). In some cases this may reduce the number of captured pieces.

In Frisian draughts there is an obligation to perform the capture with the maximum “value” . The king  is worth more than  one man but less than two men. So if you can capture a king and a man or three men, you should shot three men.

If several kings can be jumped, the rule is that the number of kings equals the value of twice the number of men minus ½. Thus if three kings can be jumped, they are worth 5½ men when determining the highest shot value.

Frisian draughts have also few interesting rules on using kings.

  • The three-move rule – a player with a king or several kings may only use the same king three times in a row to make an ordinary move. After making such three moves king is blocked.
  • The three-move rule and released king – a king that is blocked by the three-move rule is allowed to make a capture (shot). After such shot, the king is free to move up to three ordinary moves in a row again.
  • The seven move rule – this rule comes into effect as soon as a situation of two kings versus one king is reached in the endgame. The player with the two kings may make only another seven moves. If the match is not finished within these seven moves, the game results in a draw
  • Draw: one king against one king . A game can also end in a draw when both players have one king only, and the player whose turn it is is not able to jump his opponent’s king. There is one exception to this rule. If the two kings are on the ends of main diagonal, the player whose turn it is loses.

Frisian draughts are really fascinating. So bad they are so little known.

Other draughts variants with increased boards

Just like in the case diagonal draughts on 8×8 board there are more variants on larger draughts games that differ in small details from most popular variants. For example there is a draughts variant from Ghana played on a 10×10 board taht resambles Polish draughts. However in this game there is no obligation to perform the most valuable capture. In addition in the Ghanaian draughts accidentally passing up a king’s capture opportunity leads to forfeiture of the king. In this variant you lose if you are left with a single piece (man or king). In the Ghanaian draughts the board can be arranged in such manner that the lower left corner is white (not dark).

There are also Malaysian draughts, also called Singaporean draughts. This game can be played on 12×12 or 10×10 boards (very rarely on the 8×8 board). In these variant failing to do capture results in forfeiture of the  piece which has capture opportunity (so called huffing or huff rule). In the Malaysian draughts the board can be arranged in such manner that the lower left corner is white. First move can be made by black or white – this is not fixed.
