There are currently four known easter eggs in the room series. One is in all of the games except for the first Room, one is in The Room Two, the other two are in The Room: Old Sins.
Typewriter Egg
There are a few clues around the seance level in The Room Two that are keywords for the typewriter. Known keywords include:
- Null - "The Null is nothing. The Null is everything."
- Death - "The worse fate is life."
- Life - "Merely a shadow, a trick of the light."
- Light - "Where there is light, there is truth."
- Truth - "There is no truth. There is no light. There is Null."
- Home - "No place."
- Science - "She never forsook me."
- Knowledge - "Power."
- Power - "Knowledge."
- AS - "Am I the player? Am I the prey?"
- Prey - "Ask yourself this: where are the others?"
- Others - "Maggy! Grayson! Rigby! Baia! Hirst! How am I alone?"
- Maggy - "We were wrong. They came and they took us."
- Grayson - "We should have stayed away! They were never meant to be real!"
- Rigby - "We tried to fight them when they came. We tried."
- Baia - "They may take us, but our people will not follow. My. Our."
- Hirst - "We should be drowned. A captain should go down with our ship.
- Whatsinthebox (what's in the box) - "Another box."
- Crowley - "He'll find not his demons here."
- Thecircle (the Circle) - "Crowley and his blind fools."
- Demons - "Prey, along with the rest."
Feel free to add on to the list if you find anything else.
The Null Goop Egg
In the laboratory level of The Room Two, once both handles have been placed on the small font next to the battery charging station, an Egg can be found. By moving the inner handle to the S with two dots, and moving the outer handle to the ss, a skeletal face can be seen.
Radio Egg
After finding the two radio messages in The Room: Old Sins, it is possible to change the frequency on the radio to find three frequencies. These are communications of The Circle.
Station 57
"Collector Hydrus is proving a valuable acquisition. His methods may be vulgar, but there is no doubting his abilities. Nevertheless, he will be closely observed. History must not be allowed to repeat."
Station 66
"We should have foreseen the betrayal of Collector Hydrus’s predecessor. He was our most gifted collector, and his escape with our samples was unfortunate. We were unwise to trust one who valued science over faith."
Station 84
"Collector Hydrus is already showing signs of disunity. We failed to act before, and we will not be caught idle again. His current assignment will be his last."
Hint Egg
At the end of The Room: Old Sins, if the player waits to place the Null Sample in the case, three hints will come up. These hints reveal what the protagonist (Collector Hydrus) is planning on doing.
Hint 1: "I should place the Null element inside my case. My employers are waiting."
Hint 2: "Perhaps they should wait indefinitely. There is much I could achieve with a sample such as this..."
Hint 3: "No, not yet. I must bide my time."
Game Paused Egg
In the game paused menu, tap on the game paused icon five times. This will take you to a spot that gives you the option to skip your chapter. In The Room: Old Sins, this allows you to select which room to start from. This menu is not available in the original Room. It is presumably a developer tool to allow the developers to skip levels to test later ones. The developers mentioned this tool in the help section of The Room: Old Sins.
