PRIME PICKINGS

With 1 2 2 2.. modifier, each player picks 2 numbers from the available
number list, crossing them off afterwards.  He may place these numbers
anywhere in his board lists, at most 3 per list, or in an opponent list,
at most one per list.  Once 24 numbers have been entered, scoring is done
as follows:-  the row totals are added for each player, but only
the LARGEST PRIME FACTOR of this is entered as the row total.
The player of the 8th number may not make a tied contest there.

Whoever wins the majority of the three pile contests, wins the game.

This is a very interesting number game. The last moves may become very demanding because each player must search a winning combination in a set of options big enough to be explored.
