Rules:
It's easy but tricky... get four in a row, horizontally, vertically or diagonally by either occupying a space with your player OR moving one of the vertical rows one position in either direction. When a player moves a row the next player cannot move it back (slideback) until the next turn. A row can continue to move as long as it is connected to another row diagonally.Email me at esnible@acm.org
