  • A trinket
  • A pill
  • A smaller Chest

Locked Chest[ | ]

Locked Chests (or alternatively Golden Chests) require a key to open unless Isaac has Paper ClipPaper Clip or a Golden KeyGolden Key; trying to open it without the means to will push the chest instead. When opened, they'll contain one of the following:

  • Pickups: Follows the same pickup generation rules as normal chests, but spawns 2-6 batches of pickups instead. Mom's key also causes an additional 2-6 batches to spawn from locked chests, increasing the total to 4-12.
  • A Golden Chest item
  • A trinket
  • A card
  • A smaller Chest

(in Repentance) If Isaac has Gilded KeyGilded Key, all chest spawns will be replaced by Golden Chests and their contents will be modified to allow them to spawn trinkets, cards, and/or pills (which Golden Chests normally can't give) alongside normal pickups.

(in Rebirth and Afterbirth)Red Chests have the same stats inside of a Devil/Angel Room as they can teleport players into the room despite being inside it.

Bomb Chest[ | ]

Bomb Chests (or alternatively Stone Chests) are grey chests that have an appearance similar to stone. They are unique in that they will only open if hit by an explosion. They give the same rewards as Golden Chests. Stone Chests are most commonly found in Challenge RoomChallenge Rooms, Curse RoomCurse Rooms, and VaultVaults, and they will occasionally replace normal chests.

Eternal Chest[ | ]

(except in Rebirth)

Eternal Chests are similar in appearance to Golden Chests, except that they are a bright blue instead of gold and emit a pale glow. They have the same requirements to unlock and rewards as locked chests, but with an additional feature: the chest will close itself after a few seconds, at which point it can be opened again for more rewards at the cost of another key. However, there is a 25% chance the chest will give nothing when opened, and if the chest contains nothing or an item, it will not reopen and cannot give any more rewards. They can be found in Angel RoomAngel Rooms and I AM ERRORI AM ERROR rooms, and will very rarely replace normal chests and locked chests.

(in Repentance) Eternal Chests are guaranteed to pay out at least once.

Spiked Chest[ | ]

(except in Rebirth)

Spiked Chests are brown-colored chests with spikes protruding from them. Opening the chest will deal half a heart of damage to Isaac unless he has a way to resist the damage, such as with invulnerability effects or Collectible Holy Mantle iconHoly Mantle. Character The Forgotten iconThe Forgotten can also open spiked chests without taking damage by swinging their bone club. They give the same rewards as normal Chests. They can be rarely found upon completing a room or in Greed Mode Shops.

(in Repentance) Spiked Chests can also be opened without any damage being taken when using Collectible Magneto iconMagneto or holding Flat FileFlat File.

(in Rebirth and Afterbirth) Unlike other chests, they do not appear on the minimap.

Mimic Chest[ | ]

(in Afterbirth † and Repentance)

Mimic Chests appear similar to normal Chests (both for the sprite and the mini-map icon) until Isaac gets close to them, at which point they sprout spikes and act the same as a Spiked Chest.

(except in Repentance) They can be distinguished from normal Chests by their darker, brown coloring, the grayish spots on each side of the latch where the spikes will sprout from, and a tiny bloodstain.

(in Repentance) Mimic Chests can be identified through a bloodstain on their bottom-right edge. Damage from this chest is considered self-damage.

The contents inside mimic chests will change whenever their spikes pop out, (in Repentance) which can be observed with Collectible Guppy's Eye iconGuppy's Eye. The only way to get the original drops is to open it with (in Repentance)Flat FileFlat File, Collectible Magneto iconMagneto, or a melee swing attack such as Character The Forgotten iconThe Forgotten's bone club or (in Repentance)Collectible Spirit Sword iconSpirit Sword.

Old Chest[ | ]

(in Repentance)

Old Chests are similar in shape to Golden Chests, but have the color of a normal Chest and a worn-down appearance. They have the same requirements as locked chests. When opened, they contain one of the following:

Old chests can be found through the effects of Collectible Isaac's Tomb iconIsaac's Tomb and inside I AM ERRORI AM ERROR rooms.

Wooden Chest[ | ]

(in Repentance)

Wooden Chests appear similar to normal Chests but have a wooden texture. When opened, they contain one of the following:

Wooden Chests have a chance to replace regular chests, and can additionally be found in one Secret RoomSecret Room layout, as well as one Super Secret RoomSuper Secret Room layout. Before they are unlocked, Wooden Chests are replaced by normal ChestChests.

Mega Chest[ | ]

(in Repentance)

Mega Chests appear similar to Golden Chests but are larger in appearance. They require 1-7 keys to open. When opened, they contain one of the following:

Mega Chests have a 1% chance to replace any golden chest, and appear in one super secret room layout next to 2 keys. Before they are unlocked, Mega Chests are replaced by Locked ChestLocked Chests.

Haunted Chest[ | ]

(in Repentance)

Haunted Chests appear nearly identical to normal Chests, but are slightly lighter in color and are haunted by a PoltyPolty. A haunted chest deals collision damage while the PoltyPolty is inside it. When Isaac gets close enough to a Haunted Chest, the PoltyPolty will emerge and throw the chest at him, breaking it open and dealing half a heart of damage if it hits. The PoltyPolty then acts normally.

  • Haunted Chests can replace Mimic chests.
  • If the player leaves the room while the chest is in the air, it will disappear.
  • If PoltyPolties have been permanently destroyed by Collectible Eraser iconEraser, approaching the chest makes it pop open with a pink puff of smoke.

Mom's Chest[ | ]

(in Repentance)

Mom's Chest appears in HomeHome. Mom's chest has no requirements to open. It contains a Collectible Red Key iconRed Key upon the first visit (used to access the hidden closet), and on later encounters, an item from the Mom's Chest item pool.

Notes[ | ]

  • Normal chests cannot contain cards or items.
  • Consider opening adjacent Red Chests before Stone Chests; Red Chests often contain Troll BombTroll Bombs, which can blast Stone Chests open.
    • Stone Chests can also be pushed to any position in the room, which can be used to save bombs by hitting multiple targets with one blast.
  • Opening any chest (except for red chests) while on ChestChest or Dark RoomDark Room will spawn an item.
  • Chests of all types are considered pickups and will be doubled by Rune of JeraRune of Jera.
    • Mom's Chest cannot be doubled.
  • Collectible Mom's Key iconMom's Key cannot change the contents of a chest; it only causes the chest to spawn more pickups if it normally would.
  • Whenever a chest contains another chest, the smaller chest may also contain another chest. This can repeat as many times as the chance allows, but that chance is very slim by default. The smaller chest will have no different rewards than one of the same size.
    • If these smaller chests contain an item, they will appear as tiny items.
  • When using the Debug Console, a Golden Chest is referred to as a "Locked Chest" and a Stone Chest is referred to as a "Bomb Chest".
  • (except in Repentance)All of the icons for the items in the Golden Chest pool are heads or, as is the case for Collectible Bob's Brain iconBob's Brain and Collectible Infamy iconInfamy, head-related.
  • (except in Repentance) Empty opened chests may be rerolled into other pickups by using items such as the Collectible D20 iconD20, but this must be done immediately, as opened chests will disappear upon leaving the room.
    • (in Repentance) Opened chests cannot be rerolled.
  • (in Afterbirth † and Repentance) Prior to update v1.06.0182, Mimic Chests looked identical to normal Chests.

Unlockable Achievements[ | ]

Trivia[ | ]

  • Mimic Chests share the same name with a recurring Chest enemy that has appeared in Dungeons and Dragons and eventually in various video games. Mimic Chests in the games act as a chest but attempt to catch players off guard and attack them. The Mimic Chests in The Binding of Isaac, although not a living entity, may have mostly been inspired by the Mimic Chest's ability to act like chests and catch players off guard, which explains its nature.

Bugs[ | ]

Bug Bug! (except in Repentance) If a smaller chest is present in a room, re-entering the room will make the chest appear in a regular size.
Bug Bug! (in Repentance) Unless the player has enough keys, flight, or any form of teleportation, the Mega Chest can block the way of a narrow passage way and may even deny access to many other rooms such as the Boss Room, possibly softlocking your run.
