The Hollow Roblox Floor 4 is the 99 Nights in the Forest floor, and its puzzle is a memorisation test: a small green zombie NPC stands in front of a platform of glass floor tiles guarded by lasers, walks the safe route once — roughly 19 lit tiles, two to three per row — and you have to reproduce that exact path to reach the Fourth Night Relic. Step on a wrong tile and the tiles reset and the zombie demonstrates the route again.
The floor loop every run repeats
Floor 4 opens on Day 4, and the maze layout is randomized on every entry. The run is the same as on every other floor:
- Ride the elevator up and pick Floor 4.
- Find the puzzle room.
- Solve the puzzle.
- Take the Relic.
- Carry the Relic back to the elevator.
If The Deer catches you, the floor has to be restarted, which on this floor means restarting from the zombie demonstration. The maze and puzzle guide covers the shared rules, including which rooms are safe.
Finding the puzzle room
The puzzle room spawns in a random part of the maze, often near the centre. Look for a purple-tinted hall — the tint is the only consistent landmark, since the room itself moves.
When you enter the puzzle area, turn left at the first turn. The platform of glass floor tiles and the green zombie NPC are just beyond that corner, and the lasers guarding the tiles are audible before they are visible.
The Hollow Roblox floor 4 puzzle: the laser tile route
The zombie walks the safe path exactly once, and this is the only chance you get to learn it:
- The route is roughly 19 lit tiles.
- It runs two to three tiles per row, so the path zigzags across the platform rather than running straight.
- The tiles that glow during the demonstration are the ones you step on.
Watch the whole route before you move, then walk it yourself tile by tile in the same order. There is no partial credit and no checkpoint: stepping on a wrong tile resets the tiles and the zombie demonstrates the route again, so a misread row costs you the full demonstration.
Once you reach the end of the path, the Fourth Night Relic is there to take.
The Deer waits in the dark
The Deer ambushes in low-visibility areas, so stay in lit areas while you memorise the route. A long dark stretch is exactly where it wants you, and the puzzle room is one of the safe rooms you can retreat to. The evasion guide lists what each floor's monster does and which rooms are safe zones.
What Floor 4 pays out
Completing Floor 4 awards the Day 4 maze prize, the Boo & Bub badge and its matching UGC item, plus the Fourth Night Relic.
