Dartboards Numbers
Dartboards have the numbers 1  20 arrainged in such a way as to punish inaccuracy. That is to say, if someone wants to aim for the highest number which is 20 then he or she gets punished by landing on either side where there is a 1 and a 5.
Dartboard Numbers and Strategy
When playing a game like Cricket really bad players can just aim for the bottom of the board. For example, let us say a player with really bad aim typically hits anywhere within 3 numbers of where he or she aims. If the player aims at the number 3 then the numbers 16,17,19 and 15 are all within range. However, on the top of the board numbers like 20 and 18 are more isolated.
