Game Setup

This is a grouping game. We can make many deductions before starting. There are only 3 adults and each boat has at least 1 adult. So the boats can only have either one or two adults.

Each boat has four people. X and Z are in different boats. We can add that on to our main diagram

The second and third rules are both conditional statements. You can use the second rule to create a separate scenario. It’s important to draw the scenario because it involves adults, which are a limited variable.

See what happens if you put F in boat 2:

First, the second rule says G has to go in boat 2 as well. If we put F and G in 2, we must put H in 1: H is the only other adult. We already have one of X or Z in 1 and the other in 2. That leaves two spots in boat 1 and one spot in boat 2. We can’t put both V and W in boat 1 because if V is in boat 1, W goes in boat 2. (rule three)

So only Y can fill the empty space in boat 1. Then, V and W are interchangeable between boats 1 and 2.

For the other scenario, let’s see what happens when F is in boat 1. We have to put G or H in boat 2 because boat 2 needs an adult. Apart from that, we can’t deduce much.
