Alternative layouts in each case show the 'hollow' pattern better:
Code: Select all
 1 9 . 7 . . . 2 6
 2 . . 8 . 3 . . 5
 . . . . . . . . .
 . 8 . . . . . 7 1
 . . . . . . . . .
 5 1 . . . . . 4 .
 . . . . . . . . .
 3 . . 6 . 5 . . 9
 4 7 . . . 9 . 8 2   Pat's


 1 8 . 5 3 . . 6 7
 2 . . 1 . . . . 5
 . . . . . . . . .
 5 9 . . . . . 8 2
 7 . . . . . . . 3
 . . . . . . . . .
 . . . . . . . . .
 4 . . 2 . . . . 6
 3 5 . 8 7 . . 4 1  Dr. Octagon's

Hollow layouts were a topic of discussion earlier.

    Code: Select all

    O . O . . O O . O
    . . . . . . . . .
    O . . O . O . . O
    . . O . . . O . O
    . . . . . . . . .
    O . O . . . O . .
    O . . O . O . . O
    . . . . . . . . .
