Math....edit (DBO)

I'm out of cards.

When you win, just post your card in a new thread with the title BINGO! You have a whole year! First three get a prize.

How is that possible? A 5x5 grid has 25 possible permutations, and you've only posted 16. I didn't have much interest in playing, but math that doesn't add up makes me curious. ;)

If you remove the 5 vertically similar options, and one horizontally-symmetric (these cards would all have the same row possiblities), that drops to 19 cards. Are there three other similar arrangements I'm missing?

Are you counting the free space? (I have made no attempts to do the math)
