# * A set of three ones is 1000 points
# * A set of three numbers (other than ones) is worth 100 times the
#   number. (e.g. three fives is 500 points).
# * A one (that is not part of a set of three) is worth 100 points.
# * A five (that is not part of a set of three) is worth 50 points.
# * Everything else is worth 0 points.

Re: (but I feel like it's still very procedural and could be improved?)

Any chance you can eliminate the if else statements?

well .. that's the problem I'm attempting to solve ;)
