Setup and Rule Diagram Explanation
This is an Advanced Linear: Balanced game.
The variables in this game are easy to identify:
Men: J L N3
Women: K M O3
Entrees: P R S T V5
The setup, however, can be a bit more complicated because the men and women are paired in the first rule, and because there is also a rule about the men not ordering the same entree. So, we need a way to see both connections easily, and the best way to set the game up, then, is as follows:
This setup has the advantage of showing each couple (they are each vertical pair) and also showing each gender (in the rows) in a compact, easily visualized manner.
The first rule in the game establishes that the two people in each couple cannot order the same entree as each other. This can be diagrammed as:
The “E” represents “entree,” and the “E” is a shorthand way to express the five not-blocks produced by this rule.
The second rule establishes that none of the men can order the same entree:
These two rules are critical to the game, but we will consider the implications of these two rules after considering the last three rules.
The last three rules of the game place certain variables and establish several Not Laws:
With these rules represented, we can turn to combining the information already provided.
The combination of the first rule and the third rule results in the deduction that L cannot order swordfish, and the combination of the first rule and the fifth rule results in the deduction that N cannot order roast beef:
As always, examine the most restricted areas in the game. In this case, N is extremely restricted because N cannot order S, T, or R. Thus, there are only two entree choices for N: P or V. This inference is the key to the game, and leads to the final setup:
