i'm not sure if this puzzle is meant to be a joke, but it pretty much looks like it.
things like (O|RM|HHM)* which means match anything. who the hell would every write (.)(.)(.) when even capturing those is pointless in a crossword.
meh, i say.

(O|RM|HHM)* doesn't match "anything", but rather "nothing" or something quite specific. [0]
There are multiple rows in the puzzle where things _can_ match anything, but they are pretty fast limited by the opposing row/column.
