Chest (Floor)
The Chest is one of five final levels in The Binding of Isaac, alongside the Dark Room, The Void, the Corpse, and Home.
The Chest can be accessed with three methods: Touching the chest dropped by Isaac while having The Polaroid (always dropped by Mom after beating Isaac five times) equipped, or, while in the Cathedral, by using Telepills or another item that acts like Telepills, and being sent to the I AM ERROR room, or finding a Black Market on the Cathedral and going into the beam of light.
Like the Cathedral before it, the Chest consists of only one floor. In the Chest, it is not possible to bomb doors open to skip rooms. The Chest's rooms are usually devoid of Rocks and other obstacles and are mainly filled with bosses and mini-bosses. The boss of the floor is always ???.
The first room in the Chest will automatically contain 4 Locked Chests. These special chests always contain treasure room items. Rarely, these chests can also be Mega Chests or Eternal Chests. Additionally, all Chests, Bomb Chests, and Locked Chests spawned in the Chest will always contain Treasure Room Items. This means that a lot of different items can be found in the Chest when clearing rooms with items or effects that raise the chance of spawning chests. This can be useful when trying to complete the collection page. Destroying Slot Machines, Fortune Telling Machines, and all types of Beggars with the exception of the Shell Game will also spawn items.
After completing the Chest or the Dark Room for the first time, the first room of the Chest will always contain a large golden door, which can be unlocked with either the Key Pieces (combination of Key Piece 1 and Key Piece 2), Dad's Key, Get out of Jail Free Card, or Mr. ME!, allowing access to Mega Satan.

Notes
- If Isaac gets Key Piece 1 and Key Piece 2, the key will open the golden gate to fight Mega Satan, but if Isaac uses Forget Me Now, the floor will reset and Isaac won't get both Key Pieces back, making it so that the golden gate won't open again.
- It is possible to create trapdoors thanks to Reward Plates (found for example in a Secret Room). Upon entering them, the floor is restarted. If the large golden door was opened before restarting, it will be closed afterward.
- This may result in a softlock on a Daily Run to Mega Satan, if no other way of opening the door is found.
- The I AM ERROR room cannot be reached by any method in the Chest and the Dark Room.
- The I AM ERROR room can be reached by leaving a Crawl Space through an unintended direction. The room will always contain a portal leading to The Void.
- If a Red Chest is placed in the starting room, it will contain a Devil Deal, similar to the Dark Room.
Unlockable Achievements
- Dead Boy - Complete Chapter 6 without taking damage.
Trivia
- The Chest and its boss, ???, are based on the in-game backstory of Isaac locking himself in his toy chest and asphyxiating to death.
- The sprite appearance of ??? is a reference to Edmund McMillen's Dead Baby games, which are often referenced throughout The Binding Of Isaac.
- The texture of the floor may have a small chance of showing two small glowing dots that look like eyes.
- The shadow cast on the floor most likely resembles Isaac's head while opening the chest.
- In The Void, during Delirium's death animation, its boss room switches between different environments, and it always ends with a Chest backdrop.
