The Sinking City 2 Safe Codes and Combination Solutions

Quick Answer

Use this table when you need the exact code first. These are in-game puzzle answers for The Sinking City 2 locks, safes, symbol locks, and frequency puzzles.

If the lock is symbol-based instead of numeric, check the Puzzle Solutions hub for the Trident Obelisk, Statue Puzzle, and other blockers.

Church Floodgate Code: 1672

The Church Floodgate lock uses 1672. The clue combines the church founding year, 1667, with the bell being completed five years later.

Enter 1672, validate it, then pull the floodgate switch.

Apartment 5 / First Radio Shop Safe: 1908

The early safe code is 1908. Use it when the route points you toward the first Radio Shop / Apartment 5 safe and the nearby documents support the date clue.

This is an early example of how The Sinking City 2 expects you to connect a written clue to a four-digit lock instead of guessing from every number in the room.

Wireless Room Brain Puzzle: 13, 5, 36

The Wireless Room Brain Puzzle answer is:

1. 13
2. 5
3. 36

Validate each number in sequence. The clue logic starts with unlucky Friday 13, halves the rounded value to get 5, then doubles the sum of the first two numbers to get 36.

Fish Market Salt Storage Code: I, IV, IX, XVI

The Salt Storage answer is:

I -> IV -> IX -> XVI

In number form, that is 1 -> 4 -> 9 -> 16. The clue follows square numbers, which is why the third value is IX, not XI.

How to Check a Code Before Entering It

If you want the clue logic instead of only the answer:

1. Read the nearest documents first.
2. Check whether the lock wants digits, Roman numerals, or symbols.
3. Match the clue order to the lock layout.
4. Validate one complete answer instead of brute-forcing random numbers.
5. Recheck story state if the correct answer does not activate the mechanism.
