Why are dart boards numbered like that?
On a dartboard, why are the numbers set out the way they are set out?

Answer: It was invented by a carpenter in Bury in 1896 called Brian Gamlin. If you go around the dart board adding up the differences between adjacent numbers – 20 and 1 for example – it would come to 198. The highest possible it could come to is 200, but it’s well organised to reduce the chance of a lucky shot.

Answer: It's to penalise inaccuracy. You throw towards the high numbers and if you miss it, you get a low number.
(James O'Brien - not accurate enough to go definitive. Why isn't 20 bordered by 1 and 2? Was a mathematical formula used to place the numbers?)
