All Puzzle Box Solutions in RE9: Step-by-Step

Stuck on a RE9 puzzle box? Resident Evil 9: Requiem features multiple puzzle boxes hidden throughout the game, each requiring a specific sequence of celestial symbols to unlock. These ornate containers hold key items essential for story progression, so you cannot skip them. This guide provides every RE9 puzzle box solution with step-by-step instructions so you can solve them quickly and get back to surviving.

Puzzle boxes appear as small wooden containers with rotating symbol dials on the front. Each dial can be set to one of three celestial symbols: Moon, Sun, or Star. The correct combination opens the box and rewards you with a critical key item. If you are looking for safe codes instead, check our RE9 safe codes guide.

📝Puzzle Boxes Are Not Randomized

Unlike safe codes on Insanity difficulty, puzzle box solutions remain identical across all difficulty modes and playthroughs. The combinations listed here work every time regardless of your settings.

How Puzzle Boxes Work in RE9

Each puzzle box in Resident Evil 9 has four rotating dials arranged in a row. You rotate each dial to display one of three symbols: a crescent Moon, a radiant Sun, or a five-pointed Star. Once all four dials show the correct symbol sequence, the box clicks open.

The clue for each puzzle box is found somewhere in the same room or adjacent area. RE9 hides these clues in documents, wall engravings, or environmental details. Below we provide both the direct answer and the location of each in-game clue.

Puzzle Box 1: Chairman's Office

The first puzzle box is located in the Chairman's Office on the second floor of the Care Center in Rhodes Hill. You gain access to this room after obtaining the Chairman's Key during the Care Center walkthrough. The puzzle box sits on the mahogany desk near the window.

In-game clue: Examine the oil painting behind the desk. The four celestial bodies depicted from left to right correspond to the dial symbols in order.

Puzzle Box 2: Lead Researcher's Office

The second puzzle box is found in the Lead Researcher's Office inside the ARK Laboratory. This room is accessible after you clear the Bio-Research Wing and obtain the Researcher's Keycard. The puzzle box is locked inside a glass display case on the shelf behind the desk.

In-game clue: Read the research journal on the desk. Page 3 contains a diagram of four celestial symbols drawn in the researcher's handwriting with the note "sequence for personal archive."

Tips for Solving Puzzle Boxes

Finding puzzle boxes early and solving them quickly gives you access to areas with valuable resources. Here are some practical tips:

  • Search the room thoroughly before attempting a puzzle box. The clue is always nearby, usually within the same room or an adjacent hallway.
  • Listen for audio cues. Each correct dial click produces a subtle chime. If you hear a dull thud, the symbol is wrong.
  • Puzzle boxes cannot be brute-forced. Setting an incorrect combination three times in a row triggers a lockout timer of about 30 seconds before you can try again.

For more puzzle help, check out the organless corpse puzzle or the moon puzzle quartz door guide. Both puzzles are found in the same Care Center area as the Chairman's puzzle box.

💡Pair With Safe Codes

The Chairman's Office also contains a document hinting at one of the RE9 safe code clues. While you are solving the puzzle box, check the filing cabinet for a note referencing the safe codes in the area.

Frequently Asked Questions

Do puzzle box solutions change on Insanity difficulty?

No. Unlike safe codes, RE9 puzzle box solutions are identical on every difficulty including Insanity. The combinations Moon-Sun-Star-Moon and Star-Sun-Moon-Sun work on all modes.

What happens if I enter the wrong combination?

Entering an incorrect combination causes the dials to reset. After three consecutive wrong attempts, the puzzle box locks for approximately 30 seconds. There is no penalty beyond the time delay.

Can I miss a puzzle box?

The Chairman's Office puzzle box can be missed if you leave Rhodes Hill without solving it. However, chapter select lets you return after finishing the game. The Lead Researcher's puzzle box is required for story progression, so you cannot miss it.

The celestial symbols (Moon, Sun, Star) appear in several RE9 puzzles including the quartz door puzzle. The same symbol set is used across different puzzle types but each puzzle has its own unique solution.


With both RE9 puzzle box solutions in hand, you can unlock the Care Center Master Key and the ARK Access Card Level 3. For more puzzle guides, visit the puzzle solutions hub or continue with the blood specimen analyzer puzzle.
