 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
+the size of the grid, and some squares have clue 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. 
+\b All the clue signs are satisfied.

+There are two modes for this game, \q{Unequal} and \q{Adjacent}.
+
+In \q{Unequal} mode, the clue signs are greater-than symbols indicating one
+square's value is greater than its neighbour's. In this mode not all clues
+may be visible, particularly at higher difficulty levels. 
 
-In \q{Trivial} mode (available via the \q{Custom} game type
-selector), there are no greater-than signs; the puzzle is to solve
-the \i{Latin square} only.
+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
+to that neighbour's.
