+
+There are two modes for this game, \q{Unequal} and \q{Adjacent}.

+may be visible, particularly at higher difficulty levels.
-At the time of writing, this puzzle is appearing in the Guardian
-weekly under the name \q{\i{Futoshiki}}.
+In \q{Adjacent} mode, the clue signs are bars indicating
+one square's value is numerically adjacent (i.e. one higher or one lower)
+than its neighbour. In this mode all clues are always visible: absence of
+a bar thus means that a square's value is definitely not numerically adjacent

+
+You have a square grid; each square may contain a digit from 1 to
+the size of the grid. The grid is divided into blocks of varying
+shape and size, with arithmetic clues written in them. Your aim is
+to fully populate the grid with digits such that:
+
+\b Each row contains only one occurrence of each digit
+
+\b Each column contains only one occurrence of each digit
+
+\b The digits in each block can be combined to form the number
+stated in the clue, using the arithmetic operation given in the
+clue. That is:
+
+\lcont{
+
+\b An addition clue means that the sum of the digits in the block
+must be the given number. For example, \q{15+} means the contents of
+the block adds up to fifteen.
+
+\b A multiplication clue (e.g. \q{60\times}), similarly, means that
+the product of the digits in the block must be the given number.
+
+\b A subtraction clue will always be written in a block of size two,
+and it means that one of the digits in the block is greater than the
+other by the given amount. For example, \q{2\minus} means that one
+of the digits in the block is 2 more than the other, or equivalently
+that one digit minus the other one is 2. The two digits could be
+either way round, though.
+
+\b A division clue (e.g. \q{3\divide}), similarly, is always in a
+block of size two and means that one digit divided by the other is
+equal to the given amount.
+
+Note that a block may contain the same digit more than once
+(provided the identical ones are not in the same row and column).
+This rule is precisely the opposite of the rule in Solo's \q{Killer}
+mode (see \k{solo}).

+is to connect the squares to form a continuous list of numbers
+starting at 1 and linked in the direction of the arrows \dash so the
+arrow inside the square with the number 1 will point to the square
+containing the number 2, which will point to the square containing
+the number 3, etc. Each square can be any distance away from the
+previous one, as long as it is somewhere in the direction of the
+arrow.

+\H{signpost-controls} \I{controls, for Signpost}Signpost controls
+
+To play Signpost, you connect squares together by dragging from one
+square to another, indicating that they are adjacent in the
+sequence. Drag with the left button from a square to its successor,
+or with the right button from a square to its predecessor.
+
+If you connect together two squares in this way and one of them has
+a number in it, the appropriate number will appear in the other
+square. If you connect two non-numbered squares, they will be
+assigned temporary algebraic labels: on the first occasion, they
+will be labelled \cq{a} and \cq{a+1}, and then \cq{b} and \cq{b+1},
+and so on. Connecting more squares on to the ends of such a chain
+will cause them all to be labelled with the same letter.
+
+When you left-click or right-click in a square, the legal squares to
+connect it to will be shown.
+
+The arrow in each square starts off black, and goes grey once you
+connect the square to its successor. Also, each square which needs a
+predecessor has a small dot in the bottom left corner, which
+vanishes once you link a square to it. So your aim is always to
+connect a square with a black arrow to a square with a dot.
+
+To remove any links for a particular square (both incoming and
+outgoing), left-drag it off the grid. To remove a whole chain,
+right-drag any square in the chain off the grid.
+
+You can also use the cursor keys to move around the grid squares and
+lines. Pressing the return key when over a square starts a link
+operation, and pressing the return key again over a square will
+finish the link, if allowable. Pressing the space bar over a square
+will show the other squares pointing to it, and allow you to form a
+backward link, and pressing the space bar again cancels this.

+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

+
+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

+number one.

+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

+
+A white circle indicates that the square is a straight edge, but \e{at

+clear it again (or use the Undo feature).
+
+If you \e{right}-click in a square and then type a letter, the
+corresponding monster will be shown in reduced size in that square, as
+a \q{pencil mark}. You can have pencil marks for multiple monsters in
+the same square. A square containing a full-size monster cannot also
+contain pencil marks.
+
+The game pays no attention to pencil marks, so exactly what you use
+them for is up to you: you can use them as reminders that a particular
+square needs to be re-examined once you know more about a particular
+monster, or you can use them as lists of the possible monster in a
+given square, or anything else you feel like.
+
+To erase a single pencil mark, right-click in the square and type
+the same letter again.
+
+All pencil marks in a square are erased when you left-click and type a
+monster letter, or when you left-click and press Space. Right-clicking
+and pressing space will also erase pencil marks.
+
+As for Solo, the cursor keys can be used in conjunction with the letter
+keys to place monsters or pencil marks. Use the cursor keys to move a
+highlight around the grid, and type a monster letter to enter it in
+the highlighted square. Pressing return toggles the highlight into a
+mode in which you can enter or remove pencil marks.
+
+If you prefer plain letters of the alphabet to cute monster pictures,
+you can press \q{A} to toggle between showing the monsters as monsters or
+showing them as letters.
+
+(All the actions described in \k{common-actions} are also available.)

+You are given a grid of squares, which you must colour either black or
+white. Some squares are provided as clues; the rest are left for you
+to fill in. Each row and column must contain the same number of black
+and white squares, and no row or column may contain three consecutive
+squares of the same colour.
+
+This puzzle type was invented by Adolfo Zanellati, under the name
+\q{Tohu wa Vohu}. See \k{janko-unruly} for more details.
+
+Unruly was contributed to this collection by Lennard Sprong.

+
+To play Unruly, click the mouse in a square to change its colour.
+Left-clicking an empty square will turn it black, and right-clicking
+will turn it white. Keep clicking the same button to cycle through the
+three possible states for the square. If you middle-click in a square
+it will be reset to empty.
+
+You can also use the cursor keys to move around the grid. Pressing the
+return or space keys will turn an empty square black or white
+respectively (and then cycle the colours in the same way as the mouse
+buttons), and pressing Backspace will reset a square to empty.
