Fighting Numbers

Almost all menko have "Fighting Numbers" located on the back of the menko for another version of the game.  Again, this version is explained in the Rules section.  I've seen numbers with 3 digits all the way to 13 digits.  There seems to be little correlation between how high the fighting number is and what rank the Rikishi is.  I've seen a Maegashira with a much higher number than all the Yokozuna in the same set.  Below you will see examples of fighting numbers on different menko.
