Chapter 3’s Carnivale location has you solving various puzzles in Little Nightmares III. Some puzzles are easy to understand without any help, but some require assistance. During the early sections of Carnivale, you will find a machine with several buttons. You need to figure out what to do here so you can advance through the game. If you are having a tough time trying to solve the button puzzle, we have simplified the solution for you below.
How to Solve the Button Puzzle in Little Nightmares III

You need to press the correct buttons on the machine while referring to the clue printed on the sheet stuck to the wall to solve the puzzle. After taking the elevator up in Carnivale and getting the flashlight for the first time, you will have to go through a grilled gate past a doll exhibition. On the other side of the gate is where the button puzzle is located. To head inside the puzzle room, climb up the crates next to the gate.
There is a small opening on the right side once you get to the top. Go through it and fall down to reach the puzzle room. Next, find the sheet of paper on the right side of the room, roll it up by jumping up and holding on to it. This will reveal the clue to the puzzle, which hints at which buttons to press on the large machine.
Next, hit the large button at the base of the machine using Alone’s wench to start it up. When the smaller buttons light up, use Low’s arrows to press those matching the black dots on the chart. For reference, use the image below to see which buttons to press. If playing with an AI Low, they will press the correct buttons automatically.

After pressing the correct buttons, pull down the lever next to the machine with your companion to complete the puzzle and unlock the gate. There is another puzzle to solve as you explore deeper in Little Nightmare III‘s Carnivale area, so check out our guide on solving the radio puzzle to know how to do that too.
