you know that those will never be counted as part of the solution). This
is turned off by default.
+\lcont{

Note that this doesn't allow blank pegs in the solution; if you really wanted
that, use one extra colour.
+}
+
\dt \e{Allow duplicates}
\dd Allows the solution (and the guesses) to contain colours more than once;
likely it is to extend as far as it can, rather than choosing
somewhere closer.
+\lcont{
+
High expansion factors usually mean easier puzzles with fewer
possible islands; low expansion factors can create lots of
tightly-packed islands.
+}
+
\C{unequal} \i{Unequal}
\dd Size of grid in squares. There will be half \e{Width} \by \e{Height}
dominoes in the grid: if this number is odd then one square will be blank.
+\lcont{
+
(Grids with at least one odd dimension tend to be easier to solve.)
+}
+
\dt \e{Difficulty}
\dd Controls the difficulty of the generated puzzle. At Tricky level,
grid} are not constrained.)

These parameters are available from the \q{Custom...} option on the
\q{Type} menu.

\C{undead} \i{Undead}
\cfg{winhelp-topic}{games.undead}
\dd Controls the difficulty of the generated puzzle.
+\dt \e{Unique rows and columns}
+
+\dd If enabled, no two rows are permitted to have exactly the same
+pattern, and likewise columns. (A row and a column can match, though.)
