Devil Door

A Devil Room is a room in The Binding of Isaac: Rebirth. It is a room where a player can find Black Hearts, Red Chests, and trade Isaac's hearts and soul hearts for Collectibles.


The Devil Room will always consist of two Fireplaces, one Satan statue, or one of the following:

  • 2 Black Hearts.
  • 3 Red Chests.
  • 1-3 Collectibles available for trading.

One exception to these things appearing the in Devil Room is if the Mini-Boss Krampus is present, in which the room will be empty with all but four Fireplaces and Krampus. The other is if the player is located on either The Womb II, the Utero II, The Womb XL, or the Utero XL floors, in which case all items will be replaced with one Trapdoor leading to the Sheol floor.

Finding a Devil Room

Isaac can reach the Devil Room in one of the following ways:

  • There is a chance that a Devil Room may open at the end of a Boss Fight.
  • Isaac may use the Joker card to teleport to a Devil Room.
  • Isaac may be teleported to a Devil Room via a Red Chest.

Deals with the Devil

Deals with the devil may be taken as long as the player can provide either the correct amount of Red Heart Containers, Black Heart Containers, or Soul Heart Containers. Only Black Heart Containers and Soul Heart Containers may be mixed when attempting to make a deal. If the player takes a deal in which they will be left with no Heart Containers, they will die.
