"I'd like to avoid the worst sunburn of my life in here!"
— Phi, stuck in the incinerator

The Trash Disposal Room is an escape room in Zero Escape: Zero Time Dilemma located in Ward D. It is searched by Team D: Diana, Sigma Klim and Phi.


The room is divided into the incinerator and the control room. The door to the incinerator is locked, with no visible keyhole, indicating the lock is possibly magnetic.


Waking up in the room


Sigma and Diana wake up in the room and realize Phi is trapped in an incinerator.


Gas torch


Found in front of the incinerator window. Send it to Phi and have her use it on the thermometer.



Found in the shelf. For the Quest File, send it to Phi and have her unscrew it for a mini-game.



Found inside the shelf. Used to see hidden objects that can't be seen in the light. Sigma refers to it as 'Augmented Reality'.

Flathead screwdriver


Found in the incinerator. Use it on the panel. The Screwdriver also needs to be weighed and is used to unlock the toolbox and the Revolver case.



Found after unscrewing the panel. Both screws need to be put on the scale.



Used to open the panel to the red button.

Chained box


This object falls to the ground after Sigma sits in the chair. It must be given to Phi so she can unscrew it and allow Diana to receive the revolver.



Found inside of the chained box. It needs to be placed in the hole next to the chair to complete the escape room.


Letter slider

This minigame requires the player to swipe three sliders to correspond with the correct letters. A hint to the puzzle is found by looking at the trash sorting picture with the goggles. The solution is TIC.


This minigame requires Phi to weigh the two screws and the screwdriver on the scale inside the incinerator. The solution is 155g.

Quest File/Toolbox Organizer

Toolbox Puzzle


For the optional Quest File, send the toolbox to Phi and have her open it with the screwdriver.

This minigame requires the player to sort all the tools in the toolbox, so that they all fit within it. The blue X marks on all the tools must also touch a red X mark as well. If using the PC version with a controller, you must click with a mouse to rotate. Touching the tools on the 3DS and Vita versions allow you to rotate them.

Decision Game


Diana firing a gun that has a 50% chance of killing Sigma in order to save Phi.

Sigma will be trapped in a chair. The gun next to Sigma's chair has three live rounds and three blanks which has a 50/50 chance of killing him. The game calculates the odds each time so in one playthrough, he may live, while in another, he may die. However, if you choose not to shoot the gun, the incinerator will activate and kill Phi.


  • When Phi clicks on the "188 Pounds" plate in the incinerator, she has a conversation with Sigma in which we learn that he weighs about 188 pounds. This implies the chair is likely activated by weight, meaning Zero could guarantee that Sigma would have to be the one sitting in the chair for the Decision Game, even though Diana tries to sit in it as well.
  • Phi is a playable character in this escape room. She is able to investigate the inside of the incinerator.
