from the preamble, i don't see why diagonals or 1 across don't count?
anyways, my feeling is 12 - same as Ginge - but i am including 1 across.
4 upsydowny's (i think ginge made this 5?)
5 leftright's (including top line)
...and a few diagonals (left to right)
2 down,
1 up
the wind is howling and the pub shut earlyish so i would like more ale but i'm still half- cunt.
