What To Do:
When you land on (or pass) the “Wool Sale” square, you are paid for the sale of wool from your sheep. The amount you receive from the Bank, depends on the number of Sheep Pens AND any Stud Rams that you have. So count up the number of pens that you have (that’s the white sheep heads) and refer to the ‘Wool Sale Chart” in the Ready Reckoner.
If you don't own any sheep, or you only own stud rams, then you don't have any wool to sell, and therefore don't get paid anything.
