The Once Human “Boy Just Wanna Have Fun” quest turns a seemingly simple trip through High Banks into a mini detective mission involving mysterious notes, scattered numbers and one lockbox that clearly wants players to do some homework. Luckily, the mystery has a very simple ending: the correct High Banks lockbox passcode is 325.
The quest takes place in High Banks, a Level 13 location in the Broken Delta region, and begins with a mysterious note inside the settlement’s central building. From there, players are sent across the area to collect three numbers before a final clue reveals the correct order.
You can follow the entire puzzle trail and solve it the intended way, or skip the detective work and enter 325 directly into the lockbox. Either way, the prize waiting at the end is the same.

Once Human Boy Just Wanna Have Fun Passcode: The Answer Is 325
Let’s get straight to the part everyone came for.
The High Banks lockbox passcode is 325.
The lockbox can initially appear to require a four-digit password, but don’t let that throw you off. The correct solution is only a three-digit code: 325.
The passcode is also static, meaning every player uses the same answer. Game8 notes that after collecting the clues, the quest log itself reveals the solution as 325, so players don’t necessarily need to manually decode the entire mystery.
That means anyone who wants to skip the sightseeing can head straight to the lockbox, enter 325, and claim the rewards.

How to Start the Boy Just Wanna Have Fun Quest in Once Human
First, make your way to High Banks in Broken Delta.
High Banks is a Level 13 area located in the southern portion of the map. The location is around 5391, -5903, while the central bank lobby area is around 5463, -5831, depending on the map reference being used.
Head inside the central building, which is often referred to as the Gao’an Bank or High Banks lobby.
Look for the Note inside the building. Depending on the reference, it can be found near the entrance, on a table, or close to a plant or flower by the counter.
Interact with the note to start Boy Just Wanna Have Fun.
Once the quest begins, several clue locations will appear on your map. The good news is that you don’t need to collect them in any specific order. The order in which you collect the clues doesn’t matter, and Game8 notes that much of the clue text is essentially flavor information, so players don’t need to spend ages overanalyzing every sentence.
One thing worth watching out for is an Ede roaming outside the building. It can attack with ranged attacks, so getting lost in detective mode while ignoring the danger around you can get messy fast.

Where to Find the Three Numbers in High Banks
The next part of the quest sends you around High Banks to collect three numbered clues.
Uncle Lin’s House — Number 2
Start by heading toward Uncle Lin’s House, which is easy to recognize thanks to its distinctive red roof.
From the bank, turn right and continue toward the last house on the right.
Inside, look near a supply crate for the note.
This clue gives you the number:
2
The note also mentions the LK and GAMEWORLD shops and points players toward the Coffee Shop, helping guide the puzzle toward its next locations.
LK Store — Number 3
Next, head toward the LK Store, a clothing shop located toward the northern end of High Banks’ main road.
Look for the note on the floor near the entrance.
It reveals the second number:
3
Now you have two pieces of the puzzle, with one more number left to collect.
GAMEWORLD — Number 5
After visiting LK, continue to GAMEWORLD, the game store located just north of LK.
Check the counter near the entrance for another note.
This clue reveals:
5
At this point, you should have all three numbers:
2 — 3 — 5
But don’t rush back and enter them in the order you found them. One final clue tells you exactly how those numbers need to be arranged.

The Final Clue Explains Why the Code Is 325
With all three numbered clues collected, head to the WHW Cafe, also referred to as the Coffee Shop.
The cafe is located on the western side of High Banks.
Look for a note on a table near the entrance.
The final clue says:
“The third digit is the largest, and the middle number is the smallest.”
Now the puzzle becomes extremely simple.
Your three numbers are 2, 3 and 5.
The largest number is 5, so it must be the third digit.
The smallest number is 2, so it must be the middle digit.
That leaves 3 as the first digit.
The final passcode is:
325
Mystery solved.

Where Is the High Banks Lockbox in Once Human?
The High Banks lockbox is located inside the Coffee Shop/WHW Cafe.
It isn’t inside the same central building where you originally found the first note. Instead, look for the lockbox on a counter inside the cafe.
Interact with it and enter:
325
The lockbox may look like it has four digit slots, but the required password is only three digits.
Enter 325, open the box, and the Boy Just Wanna Have Fun quest is complete.
Players who aren’t interested in collecting every clue can also skip directly to this step. Since the passcode is static and doesn’t generate a different answer for individual players, 325 works for everyone.
