Game Setup

This is a grouping game. Six coworkers are playing three games, and they can only play one game each.

The rules are as follows:

F and G can’t be first, and J and L can’t be third. You can draw this directly on the diagram:

Then, F must play against G or H, and J can’t play against G. And M has no rules, so it is the random variable, which you can represent with a circle around it:

You should always look for the most restricted variable in logic games. Here, it is F: it can’t be in group 1, and it must be with G or H. That means F + G/H are in either groups 2 or 3. We can make this into two scenarios.

Scenario 1: F is second

First, let’s see what happens if we put F and G/H second:

The next most restricted variables are J and L. They can’t go in group 3. So since group 2 is full, J and L must go first:

Only M and one of H/G are left to place, so you can put them in group 3. The only uncertainty is which of H/G goes in group 2, and which in group 3:

Scenario 2: F is third

Next, let’s see what happens if we put F + G/H third:

It turns out, not much: we can’t deduce anything else. J, L, M, and one of G/H are left to place. But it’s still helpful to have this diagram, as we can see a few general constraints:

• J can’t be with G
• G can’t be first
• Beyond those two rules, any placement is allowed

The two scenarios in this game are quite limited: when F is second, almost everything is decided. When F is third, there are still only limited options for what’s left to place, as group 3 is totally full.
