Roblox The Hollow Floor 3 Grave Puzzle: Coffin Code

Roblox The Hollow Floor 3 grave puzzle is solved by calculating the lifespans on eight gravestones and setting the coffin’s three pictures to the three shortest lives in order. The dates and matching symbols can change between runs, so a screenshot password is unreliable.

After opening the coffin, take the Third Night Relic and escape back to the cinema elevator while Biter patrols Floor 3. That final return unlocks the Festering Felix head accessory and badge, not merely opening the lock.

Roblox The Hollow Floor 3 grave puzzle: Finding the grave chamber

Start in The Hollow by Roblox Presents, enter the cinema elevator and choose Floor 3. Follow the maze passages while avoiding Biter from Demonology. The room you need contains eight gravestones surrounding a coffin, with a paper riddle on the wall. Some recorded runs found it near a theatre area or a room displaying four posters. Those are clues, not permanent directions: the maze and room position can change. Look for the ring of graves rather than trying to reproduce another player’s turns.

Roblox The Hollow Floor 3 grave puzzle: read the graves

The clue asks for the three shortest lives. Each stone has a person’s name, date of birth, date of death and a picture. The eight pictured symbols in observed runs are broom, ghost, witch’s hat, bat, spider, cauldron, pumpkin and scared cat. Record each symbol beside its dates before touching the coffin lock. Read all eight, even if the first three you find seem young: the requirement is the shortest lifespans, not the three earliest death years. Keep the birth and death dates together so you do not accidentally match an age to the wrong icon.

Roblox The Hollow Floor 3 grave puzzle: Calculate the lifespans

Subtract the birth year from the death year. If the dates show someone died before their birthday during the final year, subtract one more. Someone born in December 1900 and dying in June 1940 would have lived 39 years, not 40. Sort the resulting ages from smallest to largest and mark the first three symbols. A note with symbol, birth date, death date and age makes comparing the eight graves much easier.

Roblox The Hollow Floor 3 grave puzzle: coffin combination

The central coffin has a three-slot Grave Lock numbered I, II and III. Move each slot’s arrows until the left slot shows the youngest death age, the middle the second-youngest and the right the third-youngest. Press Open. In one documented run the ages were scared cat 39, ghost 41 and spider 42; another recording used different icons. They are examples, not universal codes. For Roblox The Hollow Floor 3 grave puzzle, use the eight dates in your current room. If Open fails, check whether you used the age at death instead of the birth year or most recent death date.

The correct combination opens the coffin. Interact with the relic inside and look for the pickup confirmation before leaving. The objective is not complete just because the three symbols were accepted. Carry the Third Night Relic back through the maze towards the elevator you used to enter. Avoid stopping in exposed corridors while Biter is nearby. If you lose the path, retrace landmarks from the room where you entered rather than guessing a universal shortcut. The run only finishes when you return the relic to the hub.

Roblox The Hollow Floor 3 grave puzzle: Festering Felix reward

Ride the elevator back to the cinema lobby after collecting the relic. Two independent October 25 recordings show the Festering Felix badge after that return, and the matching Roblox-created cosmetic is a head accessory. Opening the coffin without collecting the relic will not finish the sequence. There is no Ticket purchase or Roblox Plus subscription involved in the recorded Floor 3 Relic Hunt. Check the badge notification, your avatar’s Head Accessories inventory and any hub claim prompt separately. Roblox The Hollow Floor 3 grave puzzle is distinct from Demonology’s partner-game altar quest, which grants Biter Fedora.

Roblox The Hollow Floor 3 grave puzzle: Fix an incorrect code or missing reward

A lock that rejects three seemingly correct pictures usually means you copied another player’s combination, mismatched a symbol and grave, or sorted by birth year rather than lifespan. Recalculate all eight and verify the order of the three shortest lives. If you restarted the floor, do not reuse old notes without checking the stones. For a missing reward, verify that you physically picked up the relic and travelled back by elevator. If the badge appears but the accessory is missing, check the Head Accessories inventory again after the reward notification. Roblox has not published a guaranteed instant-delivery fix. Check these points before restarting the whole floor.
