Check off the squares once a successful QSO is made using
the first letter of the call sign suffix
(the first letter that appears after the number in a call sign).
I.E. For a QSO with WW1FHC, the letter "F" can be checked off.
Squares marked "Free" do not require a QSO to be made, thus only 4 contacts are needed to complete a line.
There are a total of twelve ways to earn the 50 point bonus, by completing a row, a column, or either diagonal.
