About your map,
although I am convinced that this is not a bad idea there's something that i can't understand....
I think that only numbers from 1 to 5 give you a bonus (if you hold all the black spots on that number), and numbers from 6 to 8 don't give a bonus and nine isn't playable. Right?
when I read the title of the map I thought that a player should conquer/hold any combination of numbers that added result nine or something like that ....
Why Number Hold Nine?
Why some numbers don't give a bonus?
Looking forward your next update
