Can you guess what's wrong with this picture? lol

I give up. What's wrong with it? :/

[Astro Forever]

I couldn't find it either.

There's a 1 in the 16-30 column. Is it good that I could figure it out even though I don't know how to play Bingo?

EDIT: and I just remembered how it plays.

:d oh:

I too had the idea to check if the numbers were right in each column, but I completely missed it anyway. I don't know how. I can't even think of a good excuse!

[Big Astro Fan]

Yes, F-Man got it. lol. We played 3 games of bingo on Christmas eve before I figured it out. And that's only after B1 was called. I would make a great detective wouldn't I? lol

I feel a little better now! But, when we don't expect such a mistake, we don't look for it. Too bad, you were at a disadvantage!

Was it the only faulty card?

[Big Astro Fan]

It was we think. But we only used about 8 of them.
