Game Setup

This is a linear game. There are only four variables, but they each have to go twice.

There are only three rules.

Variables have to go besides themselves. So if you put S Monday, you also have to put S Tuesday.

You can never have day without any workshop at all. At most you can have two workshops per day.

1. P and R begin no earlier than after the second day of lighting. Some people find this rule confusing. It just means P and R come after L is done. So if the second day of lighting is on Tuesday, the P and R can start on Wednesday or afterwards.
2. It always makes sense to start with the most restricted rule when setting up a diagram.

Here, the most restricted rule clearly is the rule about L, P and R. You can’t put L in that many places. If L goes on Thursday, there’s no space for P and R to go afterwards.

The latest we can put L is on Tuesday and Wednesday.   

This is scenario 1, which I’ve drawn below.

L goes on Tuesday and Wednesday. P and R have to go on Thursday and Friday, after L. S has to go on Monday and Tuesday. Otherwise no one would go on Monday.

The second scenario is more open ended. We put L on Monday and Tuesday.

We can put P and R anywhere on Wednesday, Thursday or Friday…except we can’t put them both on Wednesday and Thursday.

Why not?  Well, then there’s no space for two S to go on Friday so nobody can go on Friday. So we have to have (at least) one of P and R on Friday. I’ve drawn two diagrams below to illustrate all this.

Note that P and R are interchangeable.

We can also put P and R on Thursday and Friday, as I’ve drawn above. S goes Wednesday.

Notice that in every scenario, both P and R go on Thursday. This has to be true, since the earliest they can start is Wednesday.   

This is the key deduction of the game, so I’ll say it again:  P and R always go on Thursday. Always. They can only go W-T or T-F.
