## Game #1 Feb 1994 Setup (specifically "unless")

I am setting up the first logic game from Lesson 7, and the last rule is confusing to me. It says "X cannot be 5 unless R is 1." Using the Unless Equation, to me it seems that "R is 1" is the term modified by the unless, and would be the necessary condition. X cannot be 5 would become to sufficient term and be reversed, so the diagram would be this:
X5 --> R1
The contrapositive would be:
Not R1 --> Not X5.

But the rule explanation is listed as
X5 --> M, N, or O1

Great, glad that you worked that out

By the way, each game has a specific forum based on test, so for example, February 1994 is here: viewforum.php?f=404
