Here’s a fun metric: this is the matrix of the communication that has taken place in the game so far. The light grey squares mean that no letters have been sent between those two players. The darker the square, the more messages have been exchanged. Blue squares means that the player on that row has sent more messages to the player in that column, while red indicates the player has received more than was sent. Purple, of course, indicates a balance.
Staring at this trying to see myself. I could do it in three guesses!
I know the answer, of course, but I’m not telling!
