Rules
The game is played on a square 10x10 board. There are two players, Black and White. Each player has four pieces in his colour. There is a sufficient supply of bi-coloured stones.

Setup
The pieces start on a4, d10, g1 and j7 for Black, a7, d1, g10 and j4 for White.

Play
Black moves first. Turns then alternate. On his turn, a player must do one of two things.
  1. Move a pawn in a straight line across any number of empty squares (orthogonally or diagonally) ending the move on an empty square. Then place a stone in your opponent's color on an empty square away in a straight line across any number of empty squares (orthogonally or diagonally) from the pawn that was last moved, or ...
  2. Move a pawn in a straight line across any number of empty squares (orthogonally or diagonally) ending the move on an empty square adjacent to an opponent's stone. The piece and the stone now define a line (straight or diagonal). If the next square of that line, going in the direction of the stone, is vacant or the next squares hold same coloured stones followed by an empty square, then your color stone is placed on that square, thus trapping the opponent's stone(s) between itself and the moved piece, and flipping them all over to the moving player's colour.

Moving is compulsory, unless impossible, in which case a player must pass. If one player cannot move anymore, the other must proceed. The game ends when neither player can move. The player with the most pieces on the board wins.
