+\k{puzzle-palace-rect}. Unlike Puzzle Palace's implementation, my version
automatically generates random grids of any size you like. The quality
of puzzle design is therefore not quite as good as hand-crafted
puzzles would be (in particular, a unique solution cannot be
guaranteed), but on the plus side you get an inexhaustible supply of
puzzles tailored to your own specification.

Solo allows you to configure two separate dimensions of the puzzle
-grid: the number of columns, and the number of rows, into which the
-main grid is divided. (The size of a block is the inverse of this:
-for example, if you select 2 columns and 3 rows, each actual block
-will have 3 columns and 2 rows.)
+grid on the \q{Type} menu: the number of columns, and the number of
+rows, into which the main grid is divided. (The size of a block is
+the inverse of this: for example, if you select 2 columns and 3 rows,
+each actual block will have 3 columns and 2 rows.)
+
+You can also configure the type of symmetry shown in the generated
+puzzles. More symmetry makes the puzzles look prettier but may also
+make them easier, since the symmetry constraints can force more
+clues than necessary to be present. Completely asymmetric puzzles
+have the freedom to contain as few clues as possible.
+
+\H{solo-cmdline} \I{command line, for Solo}Additional command-line
+configuration
+
+The symmetry parameter, described in \k{solo-parameters}, is not
+mentioned by default in the game ID (see \k{common-id}). So if you
+set your symmetry to (say) 4-way rotational, and then you generate a
+3\by\.4 grid, then the game ID will simply say \c{3x4:}\e{numbers}.
+This means that if you send the game ID to another player and they
+paste it into their copy of Solo, their game will not be
+automatically configured to use the same symmetry in any subsequent
+grids it generates. (I don't think the average person examining a
+single grid sent to them by another player would want their
+configuration modified to that extent.)
+
+If you are specifying a game ID or game parameters on the command
+line (see \k{common-cmdline}) and you do want to configure the
+symmetry, you can do it by suffixing additional text to the
+parameters:
+
+\b \cq{m4} for 4-way mirror symmetry
+
+\b \cq{r4} for 4-way rotational symmetry
+
+\b \cq{r2} for 2-way rotational symmetry
+
+\b \cq{a} for no symmetry at all (stands for \q{asymmetric})
+
+So, for example, you can make Solo generate asymmetric 3x4 grids by
+running \cq{solo 3x4a}, or 4-way rotationally symmetric 2x3 grids by
+running \cq{solo 2x3r4}.
