Day 27 - Rule
Finally! You’ve retained control of your vehicle and turn your forward thrusters on. You need to investigate this region of space to see what’s going on - why does everything look so strange outside?
As you begin driving, your center console lights up, letting you know you’re entering a heavily-controlled region. This region is divided into 49 square sectors, and each sector has a specific requirement for how it must be traversed. A few rules for traveling in this region:
You must make a single complete loop through this region, visiting each square sector exactly once and returning to where you started.
You can only travel from one square to a neighboring square, either orthogonally or diagonally.
Each region contains a flag that represents the travel restriction in place for that region.
You load up those requirements on your console, but none of the flag images come through! Looks like you’ll have to figure out which flag goes with which direction, and then find a path that creates a complete loop through this region. Once you do, you’ll be able to find out what this route is used for.
-
You'll need to figure out which flag is which rule. Use the flags along the edge of the map to help narrow down which flag is which. For example, the flag where "one path out of this square goes up" couldn't be located on the top row of the grid.
-
Once you have a complete loop through this region, look at the 9 squares with double flags. Use semaphore to decode each path in those sectors.
