Tape: "Hello, Michael. I want to play a game. So far in what could loosely be called your life, you've made a living watching others. Society would call you an informant, a rat, a snitch. I call you unworthy of the body you possess, of the life you've been given. Now we will see if you are willing to look inward, rather than outward, to give up on the one thing you rely on in order to go on living. The device around your neck is a death mask. The mask is on a spring timer. If you do not locate the key in time the mask will close. Think of it like a Venus Flytrap. What you are looking at right now is your own body, not more than two hours ago. Don't worry, you're sound asleep and can't feel a thing. Taking into account that you are at a great disadvantage here, I am going to give you a hint as to where I've hidden the key. So listen carefully, a hint is this: it's right before your eyes. How much blood will you shed to stay alive, Michael? Live or die, make your choice."
Obi Tate, Jonas Singer, Xavier Chavez, Daniel Matthews, Gus Colyard, Amanda Young, Laura Hunter and Addison Corday awoke in a house riddled with traps containing one for each person. They were breathing in a deadly gas and had to find the antidotes located in their respective traps to survive. In three hours, the door to the house would open; however, if they did not each find an antidote in two hours, they would die. Each trap contained a way to receive an antidote. A combination safe also contained an antidote, but the combination was hidden within different colored numbers written on the back of each victims neck, in the order of how they would appear on a rainbow. Several weapons are discovered including a single edged blade and a bat with nails driven through it.
Tape: "Greetings and welcome. I trust that you are all wondering where you are. I can assure you that while your location is not important, what these walls offer to you is important. Salvation, if you earn it. Three hours from now the door to this house will open. Unfortunately, you only have two hours to live. Right now you are breathing in a deadly nerve agent. You've been breathing it since you arrived here. Those of you familiar with the Tokyo subway attacks will know its devastating effects on the human body. The only way to overcome it and walk out that door is to find an antidote. Several are hidden around this house. One is inside the safe in front of you. You all possess the combination to the safe. Think hard, the numbers are in the back of your mind. The clue to their order can be found over the rainbow. Once you realize what you all have in common, you will gain a better understanding of why you're here. "X" marks the spot for that clue, so look carefully. Let the game begin."
This was a security device to keep Jigsaw's subjects in the room for the required length of time. The trap consisted of a locked door with a gun attached on the other side of the peephole, and a pulley and chain to the doorknob on the other side of the door. The barrel of the gun was aimed directly at the peephole. When activated, a bullet will be fired through the peephole and into whomever's eye was in the line of fire.
Note: Do not attempt to use this key on the door to this room.
Tape: "Hello, Obi. I want to play a game. For years, you've burned those around you with your lies, cons and deceits. Now you'll have to redeem yourself, for the games you've played with others, by playing one of mine. Inside the device in front of you are two antidotes for the poison coursing through your veins. One is my gift to you for helping me kidnap the others. The second is yours to donate. However, one of them will come with a price. Remember, Obi, once you are in Hell, only the Devil can help you out.". However, just when Xavier was about to open the door, he dropped the key, causing the door to lock.
Tape: "Hello, Xavier. I want to play a game. The game I wanna play is very similar to the one that you've been playing as a drug dealer. The game of offering hope to desperate, for a price. I think we can agree that your situation is desperate. So I offer you hope. The price that you pay is that you you must crawl into the same pit of squalor you force your customers into. By entering this room, a timer has been started. When the timer expires, the door in front of you will be locked forever. Only in finding the key before the timer runs out can you unlock and retrieve the antidote inside. I will give you just one hint as to where that key is: it will be like finding a needle in a haystack so Let the game begin."Detective Eric Matthews tried to convince Jigsaw to give up the whereabouts of the house. Jigsaw proposed a deal, stating that all Matthews had to do was sit down and have a conversation with him for a few hours, and he would get his son back. Eric resorted to brutality, and after beating Jigsaw to within an inch of his life, Jigsaw ended the game and took Matthews to the house. The detective entered the house only to find his son was not inside. Daniel was actually in the factory room with Jigsaw, locked in a timed safe and supplied with oxygen. The video feeds of the events which took place in the Nerve Gas House were a recording from hours before when the house test took place. If Eric tried to keep his patience, Daniel would have been released to him, as he was only a few feet from where he was sitting. Jigsaw even gave him a hint by saying Daniel would be 'in a safe and secure place'.
