Right well I've finally (sort of) got the score of the balls left on the table in my head: 83, 75, 67, 59, 51, 43, 35, 27 ....
What I can't for the life of me work out is how many someone needs to to 'get over the line' from there - every red/black off the table adds 8 to the score and takes 8 away from the possible so is sort of worth 16, every 2 reds/blacks off the table add 16 to the score and take 16 off the possible so is sort of worth 32. Is there a simple formula?
Eta: Something like 147 – 32n – (8m+27) where n is number of reds/blacks needed and m is number of reds on the table but I’ve no idea whether that’s anywhere near.
