The Waiting Gameble
Note: Yes, I'm still on the Tetris theme, but I promise this is the last one for now. No, I don't believe in "the one."
Background: Actual screenshot from a game. In the first game I played, I couldn't set up the double tetris with the two I-blocks until the last 5 seconds. In the game shown, I was almost at the top before the second I-block came around.
