Each of these stone slabs has two arrows on it.

Where you find it
Open the sealed entrance at the City Monument during Chapter 8.
Before you open a hint
Use the fixed arrows to eliminate directions. Check both diagonals as well as the four rows and four columns.
Hints, one at a time
These are the game's own hints, word for word from the North American version and in the same order. Open only the next one you need. In the game, Hints 1 to 3 cost one hint coin each and the Super Hint costs two.
Hint 1
Start by placing panels next to the ones already fixed in place.
The bottom-right corner of the board is a good place to start, as there's only one orientation of panel that can fit there. Check the row and column for this space, and choose a panel that will fill the space without duplicating the existing arrows.
Hint 2
The space on the bottom right of the board needs a piece with a left and right arrow on it. The left arrow should be on top, as there's already a right arrow in the third row down.
Next, let's look at the space at the top of the second column from the right. After the bottom-right panel is in position, it should be easy to work out which one goes here.
Hint 3
With the first two hints, you should have already filled in the right half of the board.
Now let's see which panel fits in the center of the leftmost column. You'll be completing two rows with this piece, so there's only one panel that could go here.
Super Hint
You should have gathered from Hint 3 that the panel with a right and down arrow goes in the center of the leftmost column on the board.
That leaves only two spaces left to fill. Don't forget that you need to pay attention to the diagonals, or else you won't know which panel goes where.
Answer and full solution
The answer and the worked explanation are hidden below. Open them when you are ready.
Show the answer
Complete the board with the arrow directions in the table below. Rows run from top to bottom; columns run from left to right.
| Row | Column 1 | Column 2 | Column 3 | Column 4 |
|---|---|---|---|---|
| 1 | Left | Up | Right | Down |
| 2 | Right | Down | Left | Up |
| 3 | Down | Right | Up | Left |
| 4 | Up | Left | Down | Right |
The bottom-right vertical slab has left above right. The upper slab in column 3 has right above left. The middle slab in column 1 has right above down. Finish the top-left horizontal pair with left, up and the bottom-left pair with up, left.
Each long diagonal also contains one of each arrow. Check those two lines if the rows and columns look right but the seal remains closed.
