Hill Hill
Logo could be two small sets of pool ball colored numbered scorekeeper balls on a rod with say race to 5 ( or any length race but not too long gets too large) and 4 of the balls pushed over left with 5 ball on right of each rod or 5 ball on the right of left rod and left of right rod putting both final balls in the center. . Another spin off logo could be, in hill hill race to 5 for instance "4-4"
If it was a race to 9 it would have the nine ball at the ends, which has some significance, but again depending on the scale might make it too large or if you make the overall appearance small enough, too hard to see the balls, too small
