Hmmm...
Without knowing the details of what the computer had chosen, it's hard
to say, but this is a possible scenario. It is possible to move symbols
around and still get the same results. Remember, it is only reporting on
the symbols that match and place, but it is not telling you which have
matched and placed. So it's possible when you switch them around that
symbols go from placed to matched and back again and still total the same.

This is because the ^ is not legal. I tried using it in REBOL and it
gave me the following grief:
** Syntax Error: Invalid string -- " ]
** Near: (line 54) Symbol_Set: [ "~" "!" "@" "#" "$" "%" "^" "&" ]
It doesn't like the ^ symbol, for whatever reason...

What??? Bugs in my code! No way!
OK, OK, I guess I gotta fix it!
That one is definitely a bug in my code.

Well, since this was more an attempt to learn REBOL than it was to
create a serious game, I just wasn't focused on complete instructions,
that's why I used the document feature rather than making it accessible
while running.
As to the "too many or too few" issue. It does tell the user that. This
appears to be a bug in REBOL. As it turns out, since I wrote my
sub-routines as refinements, if I call the refinement with it's proper
prefix (i.e. Symbols/Indicate_only_5), the script runs as expected. If,
OTOH, I forget to prefix it, which was my mistake (i.e.
Indicate_only_5), the script runs, but the refinement does not execute.
Curious...
