This game is played on the following 5x7 square board:

MOVE - On each turn, each player moves one of his stones. After the move, all (orthogonal or diagonal) adjacent opponent stones change color.
Black stones (the Octopussies) move (orthogonally or diagonally) forward to an empty cell.
White stones (the Moray Eels) can move one cell forward like the black stones, plus they can move (and jump) sideways up to two cells and backward to the previous row up to two cells (check example).
GOAL - Wins the player that captures all opponent stones.
Black also wins if he is stalemated having pieces on the last row.
The Eels move range

The left diagram shows the move range of the Moray Eels (starting at the bottom row). Don't forget that Eels can jump over other pieces.

An example

White's turn. With only one Eel left, he still moves to cell [1] (swapping c3 and d3) - b2-d2:2 - and wins in seven moves. If black replies g5-g4, then c3-e3:1, f5-e4:3, d2-c3:3, e3-d2:2, d4-e3:3, g4-f3:2, d3-d4:3, a5-b4:2, d4-b3:3, f3-e2:2, c3-d3:3 and White wins

There is a ZRF to play Moray Eels with Zillions.
