International 10x10

• International draughts is played on a 10×10 board of 100 alternating dark and light squares. Two players take part, each with 20 pieces of their own colour, called white and black.

• The board is placed so that a dark corner square is on each player's left. The pieces stand on the dark squares of the 4 rows nearest to the player. White moves first, then the players take turns.

• The object of the game is to capture or block all the opponent's pieces. A player who has no move on their turn loses.

• A man moves one square diagonally forward to a free square. It captures forward and backward: it jumps over an opposing piece to the free square right behind it and keeps capturing while it can. A piece may not jump over pieces of its own colour.

• A man that ends its move on the last row becomes a king. If it reaches the last row during a capture and can capture further backward, it goes on capturing as a man and does not become a king.

• A king moves forward and backward along a diagonal over any number of free squares. After capturing a piece it lands on any free square behind it on the same diagonal and keeps capturing, also turning onto another diagonal. A king may not jump over pieces of its own colour.

• Capturing is mandatory. If there are several ways to capture, you must choose the one that takes the most opposing pieces; men and kings count the same.

• The same opposing piece may not be jumped twice. Captured pieces are removed from the board after the whole move.

• A missed capture does not cost a piece: the server simply will not accept such a move.

• Draw:

  • the same position has occurred three times;
  • 25 moves by each side with kings only, without captures or man moves;
  • three pieces, at least one of them a king, against a lone king: at most 16 moves by each side from the moment that balance arose (a capture does not reset the count);
  • two kings, a king and a man, or one king against a lone king: 5 moves by each side.

  If the last move within the limit leaves the opponent without a move, it is a win, not a draw.

In Russia, international draughts are played under the same norms — the Russian Ministry of Sport rules for draughts (order No. 201 of 17.03.2022), section 7. The server records these draws itself, without a claim by a player or a ruling by an arbiter.
