Checkers & Draughts Wiki

Odnocvetnie Shashki ("Monocrome Checkers" - Одноцветные шашки) was invented by the famous Russian Chess problemist P. S. Artamonov. This variant is played by two people on a 100-square checkerboard.


The board is an 10×10 grid, with alternating dark and light squares. The left down square field should be dark.

The game starts with 40 pieces. There are 20 pieces on the four rows closest to each player's side. The pieces are mutually owned by both players and are therefore all of the same color as shown in the diagram above.

The men move diagonally forward (that is, towards the opponent) to the next square, when nothing can be captured. However, it is not permitted to move a man that was moved in the last turn by the opponent.

When a man reaches the furthest row from the player who controls that piece, it is crowned and becomes a damka (дамка - literally: "lady"). One of the pieces which had been captured is placed on top of it so that it is twice as high as a single piece. Unlike Russian Checkers the damka can only start a long-distance capture in another move.

Damki can move freely multiple steps in any diagonal direction exactly like a Bishop in Chess.

Men capture opponents pieces that are diagonally in front and adjacent of them by moving two consecutive steps in the same direction, jumping over the opponent's piece on the first step. Multiple opposing pieces may be captured in a single turn provided this is done by successive jumps made by a single piece. These jumps do not need to be in the same direction but may zigzag changing diagonal direction. A 180° turn, however, is not permitted.

Damki may jump over and hence capture an opponent piece some distance away and choose where to stop afterwards.

The pieces are not removed during the jump, only after the whole move.

Captures are mandatory. Players must play the sequence that captures most pieces.

The game ends when a player cannot move at his turn. It is won by the player who has captured most pieces (ordinary men and damki count the same).

If there are 4 or less pieces left, the game ends after another 15 moves even if both players are still able to move. Again the game is won by the player who has capture the larger number of pieces.
