Machines

Machines are objects that Isaac can interact with to gain a variety of rewards.

Slot Machine

Walking up to the machine and bumping into it will consume one penny and spin the slots. The machine then has a chance to spawn one of its possible rewards. Slot Machines appear naturally in Arcades, Secret Rooms and other room layouts, and can be summoned using the X - Wheel of Fortune tarot card.

If the Slot Machine is caught in an explosion of any kind, it will be destroyed, yielding various rewards (see below). The Slot Machine also has a 2% chance to self-destruct after inserting a coin, in which case it drops several random pickups or A DollarGives Isaac 99 coins.

Fortune Teller

The Fortune Teller is similar to the Slot Machine.

Fortune Tellers appear naturally in Arcades, Secret Rooms, Super Secret Rooms and other room layouts, and can be summoned using the X - Wheel of Fortune tarot card. The Fortune Teller also has a chance to self-destruct after inserting a coin, in which case it drops several random pickups or Crystal BallReveals the map (except the Super Secret Room) and drops a random Tarot Card or soul heart..

The machine will then pay with one to three of any type of coin or rarely, Child's HeartIncreases the chance of a heart pickup dropping after clearing a room, and the chance of finding a heart when opening a Chest.. Every donation has a chance of causing the Blood Donation Machine to explode, giving either a Blood BagGrants one red heart container, restores 5 red hearts, and increases speed by 0.3. or an IV BagUpon activation, Isaac loses a half-heart (one whole heart in The Womb onwards) for a random amount of coins, similar to the blood donation machine.. Alternatively, it can be destroyed with a bomb, which will cause it to drop several pickups.

Notes

• On the floors before The Womb, the machine will take a half-heart of health from each use. From the womb and onwards, the Blood Donation Machine will take one full heart instead.
• It is possible to be killed by the Blood Donation Machine.
• The machine will accept eternal hearts first, then red hearts. When Isaac's health is at half a heart (or a full heart in The Womb and beyond), the machine will drain soul hearts and black hearts instead.
• While the machine takes red hearts before Soul Hearts or Black Hearts, donations do not count as red heart damage for calculation of Devil Room chance.
• A Blood Donation Machine can be summoned using the XIV - Temperance card.
• The player can use the machine at no cost while invulnerable.
• Using a Blood Donation Machine will trigger ScapularOnce per room, when Isaac is reduced to his last half red Heart, the aura around his head temporarily vanishes and he is granted one Soul Heart. once the player is at half a heart. Leaving the room afterward and then reentering resets Scapular, allowing for further donations using Soul Hearts. Repeating this process after every Scapular activation allows the player to farm coins from the Blood Donation Machine until it breaks.
• The machine synergizes well with Bloody PennyGives a 50% chance to drop a half heart when money is collected., allowing many more plays than normal.
• With Isaac's HeartIsaac himself is now immune to all damage, and a heart familiar appears and follows Isaac. If the heart is hurt, Isaac is hurt., the machine can be used without taking any damage.
• Holy MantleAutomatically negates first taken damage in every room. does not prevent damage from a Blood Donation Machine.

Restock Box

The Restock Box is an object added in The Binding of Isaac: Afterbirth appearing in Greed Mode and rare versions of the Shop, Treasure Room, and Secret Room . Restock Boxes can be activated by donating pennies or hitting them with an explosion.

In shops, each activation will cause the box to activate all of the following effects:

• Re-rolls every item and pickup in the shop.
• Refills all empty shop slots.

The chance for the store to be restocked increases as more coins are donated.

In Treasure Rooms, the Restock Box will re-roll the item after donating enough pennies or hitting it with an explosion. It will not generate new items to replace the taken ones. It will reroll all items in the room even if they were not originally present (e.g. items from beggars).

Restock Boxes can break after the fourth guaranteed reroll with a 50% chance for every subsequent reroll that should've been successful. This will cause them to drop a small amount of money.

Mom's Dressing Table

Mom's Dressing Table is an object added in Booster Pack #2 of The Binding of Isaac: Afterbirth †. It has a 50% chance of appearing in the starting room of a floor if Isaac has more than 8 items.

If Isaac bumps into Mom's Dressing Table, his appearance will be randomly changed so that only a few of his items are displayed.

Hitting Mom's Dressing Table with an explosive will cause it to break and drop 1-4 pills.
