      How to play

      • Aim at a cell, then fire: a dot is a miss, a cross is a hit.
      • Ships lie in straight lines and never touch, not even at a corner.
      • Hits in a row pay more. A sunk ship pays for its length and gives ink.
      • Reach the target before the shots run out. Unused shots pay at the end.
      • Spend ink in the margin: sonar, mines, shells, spy notes and things you keep.
      • Keyboard: arrows aim, Space fires, 1 to 3 use the pencil case, R turns.

        Classic battle

        The standard fleet on a 10 by 10 grid. A hit gives you another shot. Sink the whole enemy fleet first.
