   <para>Each player takes it in turns to draw a line between two adjacent dots on the board. By hovering the mouse over the game board, a yellow indicator line will show you where your line will be placed when you click.
   Once you have decided where you want to draw your line, click - and the line will be drawn.
   If by drawing a line, you completed a square then this square now belongs to you and earns you a point. Each time you complete a square, you must draw another line. If your line did not complete a square then the next player(s) take their turn.
