For the castle to score you need to have a clear path of grass between it and a house tile. There's a little turn counter in the bottom corner but it could be clearer.
Oh, I thought 🔁 was for some kind of restart or reroll system and that looked like a number related to that.
What about a diagonal path from a castle? Can you introduce obstacles to make the path longer (with more turns?)
No diagonals, but the scoring is at the end so you can make the path longer through play.
