This is the canonical Build Your Backrooms update hub. It records dated, attributable evidence for the exact Roblox experience at Place ID 134363641369914, created by Wind Sun Moon [WSM]. No developer-written changelog was found in the official description or creator surfaces reviewed on 2026-08-05, so this page does not turn API timestamps, product records, or video uploads into invented patch notes.
Use each entry for what it proves. An official Roblox API checkpoint confirms current metadata at the query time. A product update timestamp confirms that Roblox’s record changed, not why it changed. A community walkthrough can report a visible feature, but it cannot establish a server-wide balance value without direct evidence.
Current status snapshot
The official Roblox experience is titled Build Your Backrooms and belongs to Wind Sun Moon [WSM]. Its public description says players build a maze, let people enter, place monsters to catch them, collect buildings and stronger monsters for more cash, explore their own or other players’ mazes, and receive monster catches while offline.
The Roblox Games API checkpoint on 2026-08-05 returned a maximum server size of six and an experience metadata update timestamp of 2026-08-05T10:04:16.9172372Z. That timestamp is useful for freshness checks, but it is not a patch date and does not disclose what changed.
The official Store records currently name +3 Monster Slots, 3000 Cash + Smiler + Empty Room + Flick Corridor, Monster Boost (-25% Cooldown), and 2X Cash. Read the live Roblox prompt for current price and terms.

2026-08-04 - Current community walkthrough coverage
Type: Community corroborated
Directly relevant walkthroughs published in the current review window independently show or describe maze construction, rooms, monster placement, visitor navigation or earnings, upgrades, and expansion. They support the broad player workflow, not an exact balance formula.
- More Andy’s walkthrough connects an intricate maze, monsters and rooms, navigation, shop upgrades, visitor currency, and optimization.
- OTTER ON ROBLOX independently connects strategic building, monster placement, visitor earnings, and progression.
- VendoPlus published focused guides about playing, earning cash, adding monsters, and adding buildings.
- Any exact number or route still needs a current in-game check.

2026-08-03 - Topic-specific player guides appeared
Type: Community reported
Multiple topic-specific videos appeared for the new player questions covered by this site. Their publication establishes current community interest and provides procedural corroboration, but titles alone do not prove every control, value, or strategy claim.
- A full how-to-play guide was published.
- Separate cash, monster, and building guides were published.
- A completion walkthrough was also found.
- No verbatim video narration or unsupported thumbnail number is reproduced here.

2026-07-22 - Current game-pass records updated
Type: Official Store record

- +3 Monster Slots confirms purchasable slot capacity.
- The 3000 Cash bundle names Smiler, Empty Room, and Flick Corridor.
- Monster Boost names a -25% cooldown effect.
- 2X Cash identifies an optional cash multiplier.

2026-06-22 - Experience creation record
Type: Official metadata

- No launch patch notes were found on the official surfaces reviewed.

What the timeline does not claim
An API updated field is not automatically a content update. Roblox can change metadata without publishing a maze, monster, building, or economy patch. This page therefore labels it as a checkpoint unless a developer-controlled note describes the change.
A game-pass record is not a complete item list. The bundle confirms named contents, but not every free unlock path or current in-game price. A YouTube upload date is not the date a feature launched. It is evidence that a player discussed the feature by that date.
Rebirth is currently Community reported from one relevant walkthrough summary. It is not promoted to an official timeline event because no matching developer note or independent direct record was verified. If the live interface presents it, record the exact current requirement and result before publishing guidance.
How to verify a reported update
Match the Place ID and creator first. Save the developer announcement URL, exact wording, and UTC date. Rejoin the official experience to avoid relying on an older server, then capture the relevant interface before and after a controlled test.
For a new building, record its visible name, source, connectors, footprint, and live description. For a monster, record the name and displayed stats without inferring hidden range. For economy changes, compare matching account and layout conditions. For codes, require a real redemption interface and reproducible result; the Codes hub currently has no verified strings.
Keep community evidence labeled. Community corroborated means at least two directly relevant independent sources support the broad observation. Community reported means a useful claim exists but lacks that independent or official confirmation. Needs in-game testing means the public evidence cannot settle it.
Where to check next
Use the Official Links guide to return to the exact Roblox experience and creator group. Check the official description and Store before relying on a search snippet. If the creator later adds a Discord, social account, or update log to an official Roblox surface, verify that link from Roblox rather than trusting a copied invitation.
For gameplay changes, compare the relevant hubs: Mazes, Monsters, Buildings, and Progression. Those pages preserve unknown values instead of freezing a speculative number into the update record.
Update FAQ
What is the latest Build Your Backrooms update?
The latest verified item on this page is an official Roblox API checkpoint from 2026-08-05. It is not represented as a named gameplay patch because no developer changelog explained the metadata change.
Are there official patch notes?
No detailed developer-written patch log was found on the official surfaces checked on 2026-08-05. This timeline uses narrow, attributed evidence instead.
Do video uploads prove an update date?
No. They show that community coverage existed by the upload date. A developer announcement or direct version evidence is needed to date a patch confidently.
Where should update records live?
Keep dated records on the single canonical /updates/ hub. That preserves one evidence trail and avoids splitting status entries across competing update routes.
