Searched in the wrong order...: AR by sum, low to high, and the very last pair was correct. Did anyone find a better way through?

Aren't all alphametics of 4+ stars basically just brute force?

Ooph, tough indeed.
@rob, I had the same strategy, A+R seems the most informative sum, given that it appears twice with different outcomes. With any given A+R combination, you can deduce O, L and the sum of S+C. In retrospect we had to start from high to low I guess, but there wasn't really any way to tell. I considered other strategies (W, C and P are not 0, W+C<10, P>3, D is an even number) but found them not very usefull. If anyone had a better strategy I would be very interested to know.
@brecher92, Sure these alphametics require brute force I guess, but it also requires logic to determine where to start, which combinations to try, in my opinion. With 10 different characters there are too many options to brute-force them all, and some options are more informative than others.
