Round the Board


Exactly what is says, you start on the big single one, and then progress right round to the big singled 20, when you have mastered this, then you add the outer bull, next stage is to do the same but using the doubles, finishing on the centre bull, this may take a while if you are a proficient player, but the aim of this routine is to make you aware of the position of all of the numbers.
