The game is played on an empty 12x14 board with the following setup:

Two notes about the board:
   1. The 2x4 central area is called the Pond, 
   2. The separation between the 7th and 8th columns below the Pond is called the finish line. 

FIRST PHASE - Each player on each turn drops one of his stones into an empty cell (not in the Pond). This is repeated until 10 stones are placed on the board (5 of each color). 
SECOND PHASE - Each player on his turn, may do one of the following options:
Move one of his stones into an adjacent cell (orthogonal or diagonal) not in the Pond;
Select one stone to jump and another stone (any color) as a pivot. The stone jumps as many cells after the pivot, as the distance between the pivot and the jumping stone. Restrictions:
Both stones must be on a straight (orthogonal or diagonal) line with no stones in-between the jumping stone, the pivot and the final cell.
The cells inside the Pond cannot be used.
After the first jump, the player places another stone on the original cell (the referee), and continues to jump with the jumping stone while it is possible and until he wants. After the jump sequence is over, the referee is removed.
CYCLE - A stone makes a cycle when it crosses the finish line twice. After that, the stone is removed and placed inside the Pond.
GOAL - Wins the player which has all his stones inside the Pond.
An example

The right white stone jumps using the black stone as pivot, landing on [1]. After the first jump, a white stone (it could be also black, the color does not matter) is placed on the cell where the jumping stone started as the referee. After that, the stone may jump to cell [2] and then to cell [3] using the referee as pivot.
