The I AM ERROR room is a rare room that isn't connected to any other room on the floor. I AM ERROR rooms contain several items and a trapdoor to the next level, which is the only exit from the room unless the character can teleport again.
Arriving at the I AM ERROR room
- The only items that can bring you to the I AM ERROR room are Undefined, Telepills, Teleport 2.0, Red Key, and Blank Card with ? Card
- The Undefined item has a fixed list of destinations (I AM ERROR room being one of the few possibilities), being a quite reliable way to reach the I AM ERROR room.
- Telepills have a very small chance of teleporting you to the I AM ERROR room.
- The I AM ERROR room can be reached by using Teleport 2.0 when all rooms on the floor have been explored, including secret rooms and the Devil / Angel room.
- The I AM ERROR room can be reached by using Blank Card with ? Card. This consumes both the Blank Card and the ? Card.
- The I AM ERROR room cannot be reached anymore in Chest, Dark Room, and the final floor of the daily challenge.
- It is possible to enter the I AM ERROR room in The Void when not on a daily challenge, despite it being a final level, and restart the floor by entering the trap door.
- The I AM ERROR room cannot be reached in The Void.
- The I AM ERROR room cannot be reached in Corpse II.
- The I AM ERROR room cannot be reached in the floor of Dad's Note (the special version of Mausoleum/Gehenna II).
- The I AM ERROR room cannot be reached in Home.
- It is possible to enter the I AM ERROR room in The Void when not on a daily challenge, despite it being a final level, and restart the floor by entering the trap door.
- During the Ascent, the I AM ERROR room will contain a beam of light instead.
- The I AM ERROR room can be reached by leaving a Crawl Space through an unintended direction.
- The I AM ERROR room can be reached by using Red Key to get out of the 13x13 boundaries of the map.
- However, while in the floors Isaac cannot reach the I AM ERROR room, red doors also cannot be created on the boundary walls.
Bug! | Attempting to enter a Black Market in a crawl space results in ending up in I AM ERROR room instead, even if the room is not normally available in the given level. |

Room Contents
The following room maps were made using Basement Renovator for cleaner viewing.
I AM ERROR rooms always contain a trapdoor to the next level and a unique shopkeeper who can be blown up. Note that all items generated in I AM ERROR rooms will pull from random item pools and the trapdoor will always be open, even if there are enemies in the room.

Notes
- Once a character arrives at the I AM ERROR room, the only ways out are the trapdoor to the next level or another teleport. As the I AM ERROR room is randomly reached, this could force the player to skip Treasure Room and/or Boss Room items if they hadn't been picked up before, and if the character cannot teleport again.
- Once Corrupted Data is achieved (beating Delirium as Tainted Eden), items that spawn in this room have a chance to be randomized as if affected by TMTRAINER.
- If a Crawl Space is spawned in the I AM ERROR room, Isaac will return to the room he was in before being teleported to the I AM ERROR room upon exiting the Crawl Space.
- Using the trapdoor in the I AM ERROR room can allow a character to reach levels not yet unlocked, like Template:Stage or Template:Stage.
- Using the trapdoor in Template:Stage or the Template:Stage will restart the level, similar to the effect of the Forget Me Now, and as of patch 1.05, the floor will generate a different layout upon restarting. The golden gate to Mega Satan will be locked if it was previously opened with Key Piece 1 and Key Piece 2 or Dad's Key. As the Key Pieces are consumed upon entering The Chest or Dark Room, the door can only be opened again for that run by using Dad's Key one more time.
- The chests present in the I AM ERROR room from Template:Stage and Template:Stage always contain items.
- Using the Rune of Jera in most of these room configurations can allow Isaac to summon and pick up a large amount of items, making the item especially effective in this room.
- If a Red Chest teleports you to a Devil Room or Angel Room from an I AM ERROR room, exiting the Devil Room will return you to the room you were in before entering the I AM ERROR room.
- Entering the I AM ERROR room from Template:Stage / Template:Stage / Template:Stage II will randomly result in a trapdoor or a beam of light. The player may have to end their run early in the Template:Stage / Template:Stage.
- It is probably not a good idea to go to the I AM ERROR room on Template:Stage / Template:Stage / Template:Stage II, because the player will be unable to pick up The Polaroid / The Negative, and can not go to either Template:Stage or Template:Stage, having to end their run in Template:Stage or Template:Stage.
- Reaching another I AM ERROR room in the above-mentioned levels would allow continuing the run beyond them, even lacking the prerequisite items.
- Note that on the 12th Rewards and onwards in the Sacrifice Room have a 50% chance to send you to Template:Stage. This may be useful if an I AM ERROR room locked you out of the The Negative.
- This rule also applies to players trying to reach Template:Stage / Template:Stage II from Template:Stage / Template:Stage / Template:Stage II. The I AM ERROR room will instead send players to Template:Stage / Template:Stage / Template:Stage I, and players will not be able to pick up Knife Piece 1.
- This rule also applies to players trying to reach Template:Stage / Template:Stage II from Template:Stage / Template:Stage / Template:Stage II. The I AM ERROR room will instead send players to Template:Stage / Template:Stage / Template:Stage I, and players will not be able to pick up Knife Piece 2.
- This rule also applies to players trying to reach Template:Stage / Template:Stage I, or Template:Stage I.
- However, in Template:Stage / Template:Stage II, if you kill Mom & Mom's Heart first, then enter the I AM ERROR room, the trapdoor inside will lead players to Template:Stage.
- This rule also applies to players trying to reach Template:Stage. The I AM ERROR room of Template:Stage / Template:Stage / Template:Stage II will instead send players to Template:Stage / Template:Stage / Template:Stage I, and players will not be able to enter the Strange Door.
- There is a rare closet room in Template:Stage and Template:Stage containing an I AM ERROR shopkeeper. This is not an I AM ERROR room, and can be exited normally.
- There is a Super Secret Room that looks like an I AM ERROR room. This is not an I AM ERROR room, and can be exited normally.

Trivia
- The I AM ERROR room is a reference to an infamous quote in the NES game Zelda II: The Adventure of Link, where a citizen from Ruto introduces himself with the sentence "I AM ERROR".
- Due to the hard numbers required to access this room, and the name of the room itself, it could be a failsafe.
Bug! | PC If you go inside a trapdoor while in Corpse, the game will crash upon entering the next floor. |
