The Hollow Roblox Event - Halloween Guide, All 9 Monsters & Free Items

Quick answer: The Hollow opened Oct 22 at 2 p.m. PT (Roblox Plus members at noon). A new maze with a new monster unlocks each day — the live finale ran Oct 31, and every reward stays claimable until noon PST on Nov 2. Missed a night? Each day's challenge keeps its own floor, so you can clear all nine before the deadline.

How the event works

1
Join The Hollow experience
It's its own experience on Roblox — search "The Hollow" in Discover or open it from the event banner on the home page. Any Roblox account (ages 9+ in most regions) can play.
2
Enter today's maze
Each day adds a new maze floor stalked by that night's monster. Explore, find the clues and locate the puzzle room.
3
Solve, grab the relic, get out alive
Complete the puzzle, take the relic and return to the lobby in one piece. Caught by the monster? You restart the run — but retries are unlimited.
4
Claim the day's badge + item
Each cleared night awards an exclusive badge and a free avatar item. All nine nights remain completable until Nov 2, noon PST.

The event poster also lists side quests across other experiences — nine "Nightly Haunts", nine "Roaming the Hollow" games and 21 "Outskirts" games — each with its own quest items. The Marketplace sells the Hollow Horseman bundle and seasonal looks for a limited time; none of the paid items are needed to finish the event.

FAQ

Question	Answer
Is The Hollow free?	Yes — the whole event and all nine reward items are free. Only optional Marketplace cosmetics cost Robux.
Can I still finish if I missed the first nights?	Yes — every night's maze keeps its own floor in the theater hub. Clear them in any order before noon PST, Nov 2.
What happens at the live finale?	A live in-game finale ran the morning of Oct 31 (creator streams ran Oct 23–31). The finale doesn't remove earlier floors — rewards stay open until Nov 2.
Is it the same as each game's own Halloween event?	No — The Hollow is a separate Roblox-run experience. DOORS, Piggy and friends still run their own in-game Halloween content.
