DROP  A player, on his turn, can
drop a stone on an empty cell. 

SHIFT  Instead of dropping a
stone, the player may decide to shift one row or column, one cell
left/right (for rows) or up/down (for columns).

All stones are shifted on the chosen
direction. If a stone is shifted offboard, it is placed on the
other end of the shifted row/column (so, for shift purposes, the
board is a Torus). 

KO rule If a player has just
shifted, the next player cannot shift that row/column. 


GOAL  A player wins
when he makes a 5 inarow (orthogonal or diagonal).

If a shift give both players a 5
inarow, wins the player that made that shift.
