+\cfg{winhelp-topic}{games.range}
+
+You have a grid of squares; some squares contain numbers. Your job is
+to colour some of the squares black, such that several criteria are
+satisfied:
+
+\b no square with a number is coloured black.
+
+\b no two black squares are adjacent (horizontally or vertically).
+
+\b for any two white squares, there is a path between them using only
+white squares.
+
+\b for each square with a number, that number denotes the number of
+squares reachable from that square going in each direction until
+hitting a wall or a black square.
+
+For instance, a square containing the number one must have four black
+squares as its neighbours by the last criterion; but then it's
+impossible for it to be connected to any outside white square, which
+violates the second to last criterion. So no square will contain the
+number one.

+Credit for this puzzle goes to \i{Nikoli}, who have variously called
+it \q{Kurodoko}, \q{Kuromasu} or \q{Where is Black Cells}.

+dotted or empty) in opposite directions.

+\cfg{winhelp-topic}{games.pearl}
+
+You have a grid of squares. Your job is to draw lines between the
+centres of horizontally or vertically adjacent squares, so that the
+lines form a single closed loop. In the resulting grid, some of the
+squares that the loop passes through will contain corners, and some
+will be straight horizontal or vertical lines. (And some squares can
+be completely empty \dash the loop doesn't have to pass through every
+square.)
+
+Some of the squares contain black and white circles, which are clues
+that the loop must satisfy.
+
+A black circle in a square indicates that that square is a corner, but
+neither of the squares adjacent to it in the loop is also a corner.
+
+A white circle indicates that the square is a straight edge, but \e{at
+least one} of the squares adjacent to it in the loop is a corner.
+
+(In both cases, the clue only constrains the two squares adjacent
+\e{in the loop}, that is, the squares that the loop passes into after
+leaving the clue square. The squares that are only adjacent \e{in the
+grid} are not constrained.)

+
+Click with the left button on a grid edge to draw a segment of the
+loop through that edge, or to remove a segment once it is drawn.
+
+Drag with the left button through a series of squares to draw more
+than one segment of the loop in one go. Alternatively, drag over an
+existing part of the loop to undraw it, or to undraw part of it and
+then go in a different direction.
+
+Click with the right button on a grid edge to mark it with a cross,
+indicating that you are sure the loop does not go through that edge.
+(For instance, if you have decided which of the squares adjacent to a
+white clue has to be a corner, but don't yet know which way the corner
+turns, you might mark the one way it \e{can't} go with a cross.)
+
+Alternatively, use the cursor keys to move the cursor. Use the Enter
+key to begin and end keyboard `drag' operations. Use the Space key to
+cancel the drag. Use Ctrl-arrowkey and Shift-arrowkey to simulate a
+left or right click, respectively, on the edge in the given direction
+relative to the cursor, i.e. to draw a segment or a cross.
