Why didn't you make the grid
where the numbers are "stored" symmetrical?

If you meant the primary display panel where the numbers drawn will "light
up", the set-up was done to the OP's specs. If you mean the top left grid
where the drawn numbers are consecutively displayed in a zig-zag fashion,
it's perhaps because I'm asymmetric <bg. Anyway, I've taken your point,
Biff, and revised the top left grid to a symmetric 15 R x 5 C

*Includes additional CF to "light up" the letters "B-I-N-G-O" in G18:G22
when the entire row of 15 numbers to the right of each letter are fully
drawn
[ via selecting G18:G22 (with G18 active), and using the formula:
=SUMPRODUCT(COUNTIF(H18:V18,$G$2:$K$16))=15 ]
