Search For The Needle Puzzle Solutions

The puzzles live in a hidden room in the Chapter 2 basement, and its door stays shut until you pull three colour-coded levers. If you cannot find the puzzles at all, this is why.

Do not search blind for the levers. Coloured wires run along the basement floor and each one terminates at its matching lever, so following a wire is faster than sweeping the room.

As you enter the puzzle room, go left. Three pedestals stand there, one red, one green, one purple, each with a number input underneath it.

The task is a counting exercise. Look at the crystals set into the puzzle room's walls, count how many there are of each colour, then enter that total under the matching pedestal. Three purple crystals in the room means clicking the purple pedestal's number three times.

The crystal count changes with every run, which is why no fixed answer exists. Count carefully and sweep the whole room — crystals can sit behind you or above eye level, and a miscount on one colour blocks the whole puzzle.

The second puzzle is a keypad lock that wants a numeric combination. As with the crystals, the combination is generated per run, so your code will not match anyone else's.

The code is written on one of the papers scattered across the floor. Only one of them carries it, so you have to check them one by one until the right sheet turns up.

Once you have it, enter it on the keypad and the second puzzle is done. This is the quickest of the three if you get lucky with which paper you pick up first, and the slowest if you leave it to chance — work the papers systematically rather than criss-crossing the room.

The last puzzle is a scrambled image made of 16 pieces that you rearrange back into the correct picture. Some pieces begin in the right position already, so check before you start moving things around.

The efficient approach is the same one that works on a physical jigsaw: place the four corners first, then the edges, then fill the middle against the frame you have built. Working outward from the centre means every piece has to be judged against a shifting reference.

There is no timer pressure on this one, so accuracy beats speed. The piece layout is randomised per run like the other two.

Completing all three puzzles opens the Alien's jail cell and shuts down the red laser trap in the basement. Those are the same event — the lasers are what the Alien's imprisonment is powering.

This is the part that catches people out. The basement key unlocks the exit trapdoor, but the lasers block the ladder that reaches it, so the key alone gets you nowhere. You need both.

“While the Basement Key unlocks the exit trapdoor, red laser traps block the ladder until you complete the secondary objective.”

Plenty of pages are written as though a single basement code exists and you just need to find the site that has it. That framing is wrong, and it is worth understanding why so you stop hunting for one.

Every one of the three puzzles is generated fresh per run — the crystal counts, the keypad combination and the picture arrangement all reroll. A published answer would be correct for exactly one player, once.

So the useful thing a guide can give you is where to look and what the puzzle is asking, which is what the sections above do. If a page offers you a specific number, it is describing somebody else's run.

Roblox's badge data puts Finished Chapter 2! at 1,025,828 awards against 13,577,221 players who have loaded the game at all — about 7.6 percent.

Since 22.8 percent have found the needle at least once, the chapter is filtering out roughly two-thirds of players who already proved they can clear a haystack. These three puzzles are the filter.

None of them are hard once you know what they want. Nearly all the difficulty is in not knowing that the levers open a room, or that the room is what unlocks the exit.
