Find the holy grail in this one screen logic puzzle made for the Confounding Calendar 2024.

Here is a copy of the rule list, since apparently there are font size problems for Mac users...

----

A road is a straight line of squares containing numbers in which each number is the length of the road in squares. In England there are 9 roads, one of each length from 1 to 9.

Each road has two ends, at each of which must be a board edge, a castle or another road.

The roads of length 2 and 6 do not end in other roads.

The castles and roads of England divide the land into six domains.

Roads connect all castles into a single network except for the two castles not adjacent to any roads.

Every character is adjacent to a castle.

The castle furthest Northwest has no character beside it.

Merlin stands in a domain containing seven empty squares.

Gawain is on the same diagonal as Morgan.

Arthur stands between four castles.

Morgan stands in the rightmost column of the map.

Lancelot, Gawain and Merlin each stand North of castles.

No road passes next to Arthur or Guinevere.

Arthur does not stand next to the road with three castles adjacent to it.

The two shortest roads each have a castle at one end. To the East of each of those castles stands a character.

The grail is located seven squares from road 5, at the centre of the domain with no character in it.

I liked it! It was challenging, and I made some mistakes with the rules myself at first, but it came together nicely in the end! Fun idea for a puzzle.

The rules need to be a lot clearer because I can barely grasp what half of them imply in the puzzle. Also, that third to last rule is quite… confounding

Quick question: Why does C16 (where the 6 is part of a road) break rule 2? Another one: Does a castle touching the side of a road connect that castle?

I didn't personally have an issue with the font size, but for me, a lot of the rules were unclear, and I couldn't (easily) test them with the checkboxes on the right. I've spent a few hours on this puzzle, just to find out it's not possible with the rules I've assumed, so I guess the rules are something different...

Some of the stuff that isn't clear to me:

Can two parallel roads connect at the end? i.e. can I have a straight line of 7 squares that say "3334444"? My immediate guess was "no, since that's not a road of length 3 and a road of length 4, it's a road of length 7."
In terms of 'connecting all the castles into a single network,' would two parallel roads running side-by-side be considered 'connected' by nature of being on adjacent squares, or does one of them have to be pointing at the other?
Also in terms of connecting all castles, does the network go through roads? for example, if I had "22C55555" (where C is a castle) are the 2 and 5 roads connected, or can it only be through other roads?
For the three characters standing north of castles, are they standing IMMEDIATELY north, or could they be (for example) one square to the right of a castle, and multiple squares north of a second castle? I assumed they had to be immediately north.
The rule about the road with three castles next to it-- I assume that implies there's only one such road? Also, does 'adjacent' mean only to the sides of the road, or does it include castles pointed to by the road? To me, it reads like it includes any in an orthogonally adjacent square.
This next one is easy to check empirically, but might still benefit from rewording. When characters are adjacent to the castle, it's not immediately clear if that includes diagonals.
For the grail rule: does 'at the center' mean exact geometric center? When you say it's located 7 squares from road 5, do you mean in the direction road 5 ends, or in any direction, including perpendicularly?

Also, you can place a number over a castle to overwrite it, and the castle doesn't come back when hitting the restart button

The intention is that you work out the semantics of the rules, some of which are fixed by other rules or by deduction, but here are the answers to your questions if you prefer:

* No
* Yes
* 2 and 5 are connected in that example
* Immediately North
* Yes, only one.
* No, it does not.
* Exact. Any.

The font size of the rule checklist is incredibly small on my macbook -- sadly can't really play this one. :(

Ah, sorry to hear that. The game is written in Unity, so unfortunately there's not much I can do about differences in behaviour on Mac/Windows/Linux or in different browsers. As a workaround, I have now added the rule list to the description.

It's the same on my PC, though. (Also, when I click the "fullscreen" button, the font gets no larger, but the left edge of the grid cuts off.)
