Binding of Isaac: Rebirth Wiki

Black Markets are unique shops that can be accessed through a Crawl Space. Black Markets are 2 rooms wide. The left side of the Black Market contains a door back to the crawlspace and a trapdoor or beam of light to the next floor (including the Dark Room Dark Room or Chest Chest, even if they haven't been unlocked yet). The center of the room contains several items from the Shop pool that can all be bought for 1 Red Heart container. Removed in Repentance Although these will not be Devil Room items, they still count as Devil deals for Angel Room generation and unlocking Azazel Azazel. Added in Repentance This is no longer the case, and Isaac can buy items from the Black Market without affecting the spawn chances of Angel rooms. The rest of the room will be strewn about with shopkeepers, pickups, and various beggars and machines.

Starting in patch version 1.03, Telepills and Undefined Undefined have a very small chance to teleport you to the Black Market, but there will be no door leading to a Crawl Space. This means that the player will be forced to take the trapdoor/beam of light if they don't have any item to teleport again, like in an I AM ERROR Room.


The following room maps were made using Basement Renovator for cleaner viewing; note that all Urns you see will be Skulls when encountered in-game. Additionally, the door to the crawlspace will close if there are enemies in the room, but the trapdoor will always be open.

  • Removed in Afterbirth Exiting the Black Market through the beam of light in Chest Chest or Dark Room Dark Room causes the floor to restart (in a similar fashion to Forget Me Now Forget Me Now), as there are no floors further than these two. This can come in handy to gather a lot of items. The same applies to I AM ERROR.
    • Added in Afterbirth Black Markets and I AM ERROR can no longer be accessed in The Chest or Dark Room.
  • Added in Afterbirth † Black Markets and I AM ERROR can be found in The Void The Void. Using the trapdoor causes the floor to restart (in a similar fashion to Forget Me Now Forget Me Now).
    • Added in Afterbirth † Players can no longer access the Black Market through the wall glitch. However, it is still possible to access the Black Market using the glitch via special circumstances including having Ipecac and The Inner Eye.
  • The Lost The Lost can take items from the Black Market for free, just like with regular devil deals.
    • Added in Repentance The Lost can take only one item from each selection of items. When an item is taken, the others disappear.
    • Added in Repentance If a Black Market is found in the Mirrored World and is populated using a Restock Machine, it will follow the rules of the non-mirrored character. Despite playing as The Lost in this area, multiple items can be purchased, and health will be deducted from the non-mirrored character, possibly resulting in death.
  • Added in Repentance When playing as Keeper Keeper, the items are sold for money instead, making it no different from a regular Shop.
  • Added in Repentance When two crawl spaces lead to a Black Market in the same floor, they lead to the same Black Market
  • Added in Repentance During the Ascent, crawlspaces with Black Markets lead to an I AM ERROR room instead


Bug Bug! Removed in Afterbirth † Creating and entering a trapdoor which also leads to a Black Market (for example by We Need to Go Deeper! We Need to Go Deeper! or an Rune of Ehwaz Rune of Ehwaz rune) results in not being able to escape the Black Market other than going to the next floor.
Bug Bug! Added in Repentance Using Telepills or Undefined Undefined to enter a black market in the mirrored world on Downpour Downpour II and Dross Dross II will generate a black market with no items and no exits. Without any other means of teleporting, this will softlock a run.
