This is my friend Grant's favoritest game. He will play it with anyone at any time. Because he's very very good at it.
Basically, people (at least two, but no real limit) take turns dealing Scrabble tiles out onto the table. As you see words come up, you call them out and grab the tiles. You can combine new letters with existing words to 'steal' words from other players. You can play with a 3-letter or 4-letter minimum. Whoever ends up with the most words after you run out of letters, wins. Sometimes we add up the points attached to each letter to determine the winner.
I am not usually very good at this game because it requires too much of a certain kind of thinking, even though I was a Hist & Lit major in college. But the other day I played with another friend, and won (for once). I was so proud of my words that I took a picture. Yes, I know, I had accidentally put away the F in 'adrift' before I remembered to take the picture.
