Brawl Stars Find Gus Hallway Locked usually means one of the Phase 2 prerequisites has not registered yet. The Hallway does not unlock only because the October 3 phase date has arrived. You must finish the Phase 1 entrance and then win three battles.
The quickest fix for Brawl Stars Find Gus Hallway Locked is to check the event map before repeating the old puzzle. The Entrance needs its completion state, and the three battle circles for the Hallway requirement need to be green. Once both are true, the Hallway becomes the next playable room.
Brawl Stars Find Gus Hallway Locked: exact unlock requirement
Complete the October 1 entrance route first. That means solving the required grave sequence, rebuilding Gus’s grave, spelling GUS and using the resulting key on the central story door.
After that, play and win three normal battles. Brawl Stars Find Gus Hallway Locked is expected until those wins have been counted, even if you already collected every optional Air Drop from the first room.

Do optional Phase 1 secrets count?
No. MONSTER, the extra DYNAMIKE interaction, MORTIS and MRTS MORTAY are bonus routes. They are useful for extra Air Drops but they are not the trigger that clears Brawl Stars Find Gus Hallway Locked.
The important state is the required entrance completion plus the three wins. Chasing every optional reward will not substitute for those battle results.
Why are my three wins not showing?
If Brawl Stars Find Gus Hallway Locked remains after you believe you have won three times, return to the event map and check whether each circle actually turned green. A match that ended before your result was recorded or a stale event screen can make progress look behind.
Finish another normal battle if necessary, return to the lobby and reopen the Find Gus event. Do not reinstall Brawl Stars or clear account data for a simple event-state problem.
Does the right chest need to be opened first?
No. The unsolved right-side chest from Phase 1 is separate from Brawl Stars Find Gus Hallway Locked. The Hallway can open while that old box is still closed.
The key found later in the Hallway also has a different purpose. It opens the small safe inside the closet and provides Shade’s cymbals. It is not a delayed key for the original right chest.
What confirms the Hallway is ready?
The event map is the best confirmation for Brawl Stars Find Gus Hallway Locked. Phase 1 should be checked off and the three battle-win indicators should be complete. The Hallway then becomes selectable instead of remaining greyed out.
Once inside, the first practical interaction is the screwdriver at the lower-right edge of the room. If you can enter and collect it, the unlock requirement is finished.
What if the Hallway opens but the puzzle does not work?
That is no longer Brawl Stars Find Gus Hallway Locked. At that point, use the Phase 2 walkthrough and check the item sequence: screwdriver, jack-in-the-box, frying pan, closet, fish, clock, shovel, radio, skull key, cymbals and Shade.
Separating an unlock issue from a puzzle-state issue saves a lot of wasted tapping. The map solves the first problem; the Hallway item sequence solves the second.
Quick unlock check
For Brawl Stars Find Gus Hallway Locked, confirm Entrance complete, then three wins, then reopen the event map. You do not need the Damian Pin, every Phase 1 secret or the old right chest before starting Phase 2.
Does a loss remove Hallway progress?
The requirement is three wins, not three consecutive wins. Losing a match between victories does not erase the wins that have already registered on the event map. Use the green circles as your progress check instead of counting the total number of matches played.
If you leave the game and return later, re-open the Find Gus screen and check the indicators before assuming progress was reset.
