"It is the final tie-breaker, therefore, the destinations of checkers that end up as blots or spares when they are move[d] in a play, that decides the ranking."

Mike's explanations are great -- both accurate and thorough. However, I can't resist but to occasionally point out the use of extra phrasing. To me, "destination" and "when they are moved in a play" are redundant. If a checker has a DESTINATION (as opposed to merely a location), it must be being moved in the indicated play!

Perhaps I use too few words at times, but to me the following sentence suffices:

The final tie-breaker is the destinations of blots or spares.

By following the hit-more-six rule, you have already established that the plays hit the same number of checkers (zero) and own (i.e., make or keep) the same points, and all that remains (the "final tie-breaker") is comparing blots/spares. Admittedly, one must understand that when referring to a "blot" or "spare," we mean how that checker ENDS UP, not to its status before the play is made. We only have to look at the DESTINATION points of the checkers. Ignore the points of origin (and any other non-destination locations).

The C-family candidates are 24/18 11/5, and 24/21 8/5. The checker that covers the 5pt is not (i.e., it does not end up as) a blot or spare. The only blot/spare is on the far side of the board. That is, to break the tie, you merely need to see that the (destination of the) 18pt outranks the 21pt -- the former being closer to (Blue's own) 6pt.

.....C (Cross) = 24/18 11/5
.......c (cross) = 24/21 8/5
