This article is about the objects called chests. For the floor, see The Chest.

Chests are objects that contain other objects, items, trinkets, pickups, enemies, and more. There are eleven types of chests.

Chest

Normal chests have no requirements to open. When opened, they will contain one of the following:

• Pickups (very common) - If this is the reward, 1-3 of the following batches of pickups will spawn. The same batch can be chosen multiple times. If Isaac has Mom's Key, an additional batch of 1-3 pickups spawns, up to a total of 2-6.
  • 1-3 random coins
  • 1 random bomb
  • 1 random key
  • 1 random heart
• A Trinket (uncommon)
• A Pill (uncommon)
• Another, smaller Chest (very rare)

Normal chests cannot contain cards or items.

Golden Chest

Golden chests require a key to open unless Isaac has Paper Clip or a golden key; trying to open it without the means to will push the chest instead. When opened, they'll contain one of the following:

• Pickups (very common) - Follows the same pickup generation rules as normal chests, but spawns 1-6 batches of pickups instead. Mom's key also causes an additional 1-6 batches to spawn from locked chests, increasing the total to 2-12.
• An Item (slightly uncommon)
• A Trinket (uncommon)
• A Card (uncommon)
• Another, smaller Chest (very rare)

Golden chests cannot contain pills.

See the following item pools for a list of items Locked Chests can contain: Golden Chest (Item Pool) and Golden Chest (Greed Mode Item Pool)

Red Chest

Red Chests are most commonly found in Curse Rooms and Devil Rooms, but can also occasionally replace normal chests. If Isaac is holding The Left Hand, all chests will turn into Red Chests. They can contain the following:

• 2 Troll Bombs
• 1 Megatroll Bomb
• 2 Spiders
• 1-2 Soul Hearts
• A Red Chest pool item
• 1-2 pills
• Teleport to the Devil Room or Angel Room
• 1-3 Blue Flies
• 1-3 Blue Spiders

Stone Chest

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 Rooms, Curse Rooms, and Vaults, and they will occasionally replace normal chests.

Eternal Chest

Eternal Chests are similar in appearance to Golden Chests, except that they are a bright blue instead of gold and emit a pale glow, like a Soul Heart. 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 Rooms and I AM ERROR rooms, and will very rarely replace normal chests and locked chests.

Eternal Chests are guaranteed to pay out at least once.

Spiked Chest

Spiked Chests are purple 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 Holy Mantle ( or if it's on The Chest/ Dark Room, where they are free to open.) The 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.

Unlike other chests, they do not appear on the minimap.

Mimic Chest

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. They can be distinguished from normal Chests by their darker, purplish-brown coloring, the grayish spots on each side of the latch where the spikes will sprout from and the bloodstain.

The sprite for mimic chests is different and looks more similar to a normal chest. Mimic chest can be identified with blood stain on the bottom right edge.

Old Chest

Old Chests are similar in appearance 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:

• 1-3 soul hearts
• 1-3 trinkets
• An item
  • Any Mom items except Mom's shovel
  • Any Dad item except Dad's note
  • Any angel room item

Wooden Chest

Wooden Chests appear similar to normal Chests but have an appearance similar to wood. When opened, they contain one of the following:

• 2-2 cards or runes (common)
• 2-3 pills (common)
• An item (rare)
  • Mom's box
  • Wooden spoon
  • Wooden nickel
  • Stigmata
  • Metronome
  • Blood of the Martyr
  • Toothpicks
  • Lil Chest
  • The Ladder
  • Mr. Me

Mega Chest

Mega chests appear similar to Golden Chests but are larger in appearance. They require 2-7 keys to open. When opened, they contain one of the following:

• 2 Items
• Pickups
  • 1-19 random coins
  • 1-9 random bombs
  • 0-6 random keys
  • 0-9 random hearts
  • 0-2 random cards or runes
  • 0-2 trinkets

Unlocked by defeating Mega Satan as Tainted Isaac

Haunted Chest

Haunted Chests appear nearly identical to normal Chests until Isaac gets close to them, at which point a Polty picks up the chest and throws it at Isaac, doing half a heart of damage and breaking open the chest. The Polty then acts normally. Haunted chests can be discerned from a distance by their slightly paler colors.

Unlocked by defeating Mega Satan as Tainted Lost

Mom's Chest

Mom's Chest appears in Home. Mom's chest has no requirements to open. Contains a Red Key upon the first visit. Contains a random Mom-related item or Red Key upon subsequent visits of Home.

Notes

• Consider opening adjacent Red Chests before Stone Chests; Red Chests often contain Troll Bombs, which can blast Bomb 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 The Chest or Dark Room will spawn an item.
• Chests of all types are considered pickups and will be doubled by Rune of Jera.
• Empty opened chests may be rerolled into other pickups by using items such as the D20, but this must be done immediately, as opened chests will disappear upon leaving the room.
  • Opened chests can no longer be rerolled.
• Mom'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.
• All of the icons for the items in the Golden Chest pool are heads or, as is the case for Bob's Brain and Infamy, head-related.
  • The Golden Chest pool also includes bags, such as IV Bag or Sack of Pennies.
• For unknown reasons, chests can rarely transform into other types of chests upon re-entering a room.
• If a chest contains an item, the opened chest will be considered an empty item pedestal to duplicate using Diplopia.
• Prior to update v1.06.0182, Mimic Chests looked identical to normal Chests.

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.

Bug!	If a smaller chest is present in a room, re-entering the room will make the chest appear in a regular size.
