Yeah, it's bingo, so you don't have to do the whole table. There's this whole points this and the top 3 get icon sets but I don't care about that.

So at the minimum you need to do 1 fill before December whatever-the-date was in order to play the next round. You have to finish a BINGO before December Whatever in order to receive points. The amnesty period lets you finish a BINGO and still get the participation banner, but you won't get points.

But basically you can do 5 in a row in any direction, or you can do an X through the wild card, or a + through the wild care. Or just the border. Or a blackout, where you finish the entire thing. And there's a few others that I can't remember off the top of my head. But at the minimum it's 5 in a row.
