This game is played on the following 8x8 square board:

GOAL CELLS - The two middle cells on the player's last row.
TURNS - At each turn, each player must move one of his stones in just one of the following ways:
On the first four rows (the player's side) a stone may slide orthogonally any number on empty cells (so, there's no jumps). However, the stone cannot cross to the opponent's side.
On the whole board, the stone may jump over an adjacent (orthogonal or diagonal) friendly stone to the immediate empty cell. Jumps can be multiple but they're not mandatory.
In either type of move, the stones cannot cross or stop over the his own goal cells.
GOAL - Wins the player that moves one of his stones into one of the goal cells.

This set of rules is open to a simple drawish strategy, for e.g., White may tie the game by placing stones at c1,c2,d2,e3,f2,f1 leaving two other stones to move around. A possible solution would be to allow jumps over enemy pieces that are adjacent to the player's goal cells.

An example

Black's turn. Black may win by executing the following jump sequence (using the marked stone): c5-e7-e5-g5-g3-e1.
