Chapter 49: Rome
You are given a grid split into regions, containing some arrows and one or more circled goal cells. Fill every empty square with an arrow pointing up, down, left, or right so that:
- Each outlined region contains different arrow directions.
- Following the arrows from any square eventually leads to one of the circled goals.
This puzzle type is Nikoli’s Roma and is documented here from x-sheep/puzzles-unreleased.
