Build Your Backrooms Next Update: Schedule, Start Times & Next Countdown
Build Your Backrooms drops you into the internet’s most unsettling liminal spaces and dares you to survive them, and its developer keeps the experience evolving with a steady run of major updates. Each new update reworks how you navigate — or stalk — the maze, and with about 3,500 players inside at any given moment, an update going live is the moment the whole community logs on together.
None of this is left to chance. A new update lands about every every ~22 days, and each one consistently goes live in one of two launch windows chosen so players across the world’s time zones can be online for it. The next update is scheduled for Friday, September 4 at 11 AM ET — the exact start time and the usual windows are on the card below.

How often updates land
Build Your Backrooms has shipped 2 major updates so far, arriving roughly every every ~22 days. Rather than a single fixed hour, launches have clustered into two time-of-day windows: Thursdays at 12:00 PM ET and Fridays at 11:00 AM ET. The two slots exist for the same reason any global game staggers a launch — an hour that suits players in New York falls in the middle of the night for players in Sydney, so spreading the drop keeps it reachable for as many regions as possible.
Here is how those two windows land across the major world time zones:
| Region | Thursday window | Friday window |
|---|---|---|
| US Eastern (ET) | 12:00 PM | 11:00 AM |
| US Pacific (PT) | 9:00 AM | 8:00 AM |
| UK (BST) | 5:00 PM | 4:00 PM |
| Central Europe (CEST) | 6:00 PM | 5:00 PM |
| India (IST) | 9:30 PM | 8:30 PM |
| Japan (JST) | 1:00 AM (next day) | 12:00 AM (next day) |
| Australia (AEST) | 2:00 AM (next day) | 1:00 AM (next day) |
What’s new in the latest update
The most recent update leans into the game’s horror core rather than just piling on cosmetics. Its headline additions:
- A new style of maze survival that changes how a run plays out from start to finish.
- The option to play as the Monster, flipping the usual escape into a hunt.
- A brand-new Monster to learn, avoid, or embody.
- A round of new features alongside broader performance optimization.
Tips for catching the next update
- Pick the window that suits you: the Thursday noon ET slot and the Friday 11:00 AM ET slot cover most regions, so choose whichever falls at a workable hour where you are and check the table above.
- Set a reminder for the next start time on the card rather than refreshing all day — updates go live at the top of their window.
- Missing one isn’t a problem. A fresh update comes around again within a few weeks, and everything the previous update added stays in the game.
- Log in early in the window if you want the least crowded servers; the first hours after a drop are the busiest.
How updates fit Build Your Backrooms’ rhythm
Build Your Backrooms doesn’t juggle a long calendar of parallel events — its update drops are the game’s main beat. Each one is the reset point where the community gathers, tests the new content, and settles into the changes until the next arrives. With over about 46,000,000 visits and hundreds of thousands of players marking it a favorite, that steady update cadence is what keeps the maze worth returning to.
