+
+You have a square grid; each square may contain a digit from 1 to
+the size of the grid, and some squares have greater-than signs between
+them. Your aim is to fully populate the grid with numbers such that:
+
+\b Each row contains only one occurrence of each digit
+
+\b Each column contains only one occurrence of each digit
+
+\b All the greater-than signs are satisfied.
+
+In \q{Trivial} mode, there are no greater-than signs; the puzzle is
+to solve the \i{Latin square} only.
+
+At the time of writing, this puzzle is appearing in the Guardian
+weekly under the name \q{\i{Futoshiki}}.
+
+Unequal was contributed to this collection by James Harvey.

+\IM{Unequal controls} controls, for Unequal
+
+Unequal shares much of its control system with Solo.
+
+To play Unequal, simply click the mouse in any empty square and then
+type a digit or letter on the keyboard to fill that square. If you
+make a mistake, click the mouse in the incorrect square and press
+Space to clear it again (or use the Undo feature).
+
+If you \e{right}-click in a square and then type a number, that
+number will be entered in the square as a \q{pencil mark}. You can
+have pencil marks for multiple numbers in the same square.
+
+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 number, or you can use them as lists of the possible
+numbers 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 number again.
+
+All pencil marks in a square are erased when you left-click and type
+a number, or when you left-click and press space. Right-clicking and
+pressing space will also erase pencil marks.
+
+(All the actions described in \k{common-actions} are also available.)

+
+\dd Controls the difficulty of the generated puzzle. At Trivial
+level, there are no greater-than signs (the puzzle is to solve the
+Latin square only); at Recursive level backtracking will be required
+(but the solution should still be unique); the levels in between
+require increasingly complex reasoning to avoid having to backtrack.

+\cfg{winhelp-topic}{games.galaxies}
+
+You have a rectangular grid containing a number of dots. Your aim is
+to draw edges along the grid lines which divide the rectangle into
+regions in such a way that every region is 180\u00b0{-degree}
+rotationally symmetric, and contains exactly one dot which is
+located at its centre of symmetry.
+
+This puzzle was invented by \i{Nikoli} \k{nikoli-galaxies}, under
+the name 'Tentai Show'; its name is commonly translated into English
+as 'Spiral Galaxies'.

+\H{galaxies-controls} \i{Galaxies controls}
+
+\IM{Galaxies controls} controls, for Galaxies
+
+Left-click on any grid line to draw an edge if there isn't one
+already, or to remove one if there is. When you create a valid
+region (one which is closed, contains exactly one dot, is
+180\u00b0{-degree} symmetric about that dot, and contains no
+extraneous edges inside it) it will be highlighted automatically; so
+your aim is to have the whole grid highlighted in that way.
+
+During solving, you might know that a particular grid square belongs
+to a specific dot, but not be sure of where the edges go and which
+other squares are connected to the dot. In order to mark this so you
+don't forget, you can right-click on the dot and drag, which will
+create an arrow marker pointing at the dot. Drop that in a square of
+your choice and it will remind you which dot it's associated with.
+You can also right-click on existing arrows to pick them up and move
+them, or destroy them by dropping them off the edge of the grid.
+(Also, if you're not sure which dot an arrow is pointing at, you can
+pick it up and move it around to make it clearer. It will swivel
+constantly as you drag it, to stay pointed at its parent dot.)
