What about the decryption in the southeast of Hatch Island?

1, find a suitable perspective to observe organs.

2. There is a camp nearby to investigate and introduce the organization's solutions.

3. The orientation of the square represents different numbers, north 1, east 2, south 3, west 4, hat 4 and empty seat 9. The goal is that the numbers in nine positions are different, but the sum of diagonal values of rows and columns is the same.

Because there is more than one topic, it is easy to knock on the box in the game, so I decided to use tools to solve it.

5. The formula result of the spreadsheet will change automatically with the change of the content of the source table. This problem only needs the addition formula, which is very simple.

6. Open a spreadsheet software, such as Microsoft Excel, Kingsoft WPS (supporting mobile phones) and LO Calc (open source software).

7. In the 1 section, mark the interactive box with 1, and mark the rest with 0. Below the interactive box is purple.

8. Part II: Mark the squares with hats with 4, and mark others with 0.

9. Part 3, mark non-interactive squares with numbers, north 1, east 2, south 3, west 4, use 9 for no squares, and use 0 for the rest.
