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?
