+You have a grid of squares. Your aim is to draw a diagonal line
+through each square, and choose which way each line slants so that
+the following conditions are met:
+
+\b The diagonal lines never form a loop.
+
+\b Any point with a circled number has precisely that many lines
+meeting at it. (Thus, a 4 is the centre of a cross shape, whereas a
+zero is the centre of a diamond shape \dash or rather, a partial
+diamond shape, because a zero can never appear in the middle of the
+grid because that would immediately cause a loop.)

+Left-clicking in a blank square will place a \cw{\\} in it (a line
+leaning to the left, i.e. running from the top left of the square to
+the bottom right). Right-clicking in a blank square will place a
+\cw{/} in it (leaning to the right, running from top right to bottom
+left).
+
+Continuing to click either button will cycle between the three
+possible square contents. Thus, if you left-click repeatedly in a
+blank square it will change from blank to \cw{\\} to \cw{/} back to
+blank, and if you right-click repeatedly the square will change from
+blank to \cw{/} to \cw{\\} back to blank. (Therefore, you can play
