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 Dollar and becomes unusable. The D4 is unlocked when 30 Slot Machines are destroyed (via explosion or overloading) by the player. When blown up in the Dark Room or Chest, it will drop a collectible from the Treasure Room pool, much like brown and golden Chests.

On hard mode, the chances of winning at the Slot Machine are halved.

Possible Rewards from Coins

• Bombs
• Hearts
• Keys
• Coins
• Pills
• Pretty Flies
• Black Flies
• A Dollar

Possible Rewards from Destroying

When you destroy the machine, there is a:

• 10% chance to drop a random pill
• 10% chance to drop a random trinket
• 1% chance to drop a Brown Chest
• 1% chance to drop a Golden Chest
• 78% chance to drop 2-3 random pickup groupings; for each grouping, there is a

  • 20% chance to drop a random heart
    • if Daemon's TailMost non-specific heart drops become black hearts, but heart drops are significantly less common. is held, there is an 80% chance to prevent this grouping from being chosen; if prevented, another pickup grouping will be chosen instead.
    • if chosen, there is a 50% chance that this counts as 2 pickup groupings.
  • 15% chance to drop a random key
  • 30% chance to drop a random bomb

There is a 33% chance of an extra pickup grouping spawning if you are holding Lucky ToeIncreases Luck by 1..

Furthermore, if the 78% chance to drop the pickup groupings is selected, there is a 33% chance for the following conditions to occur:

• if Ace of SpadesIncreases the chance of tarot cards or playing cards dropping after clearing a room, and the chance of finding cards when opening a chest. is held, there is a 50% chance to spawn an extra random card.

Note that only 1 additional item can spawn from this 33% chance. In the case of having multiple matching trinkets, the conditions are checked in order.

Fortune Teller

The Fortune Teller is similar to the Slot Machine. Bumping into the machine costs one penny, which will either cause a random fortune or special seed to be displayed on-screen or cause the machine to spawn one of its possible drops. 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 Ball. Like the Slot Machine, Fortune Tellers will also drop a random collectible item when destroyed in the Dark Room or Chest.

When you insert a coin into the machine, there is a

• 65% chance of a fortune or seed text
• 35% chance of a reward; if it is a reward, there is a
  • 30.56% chance to drop a soul heart
  • 30.56% chance to drop a random trinket
  • 30.56% chance to drop a random card or rune
  • 5% chance to self-destruct into random pickups
  • 3.33% chance to self-destruct into a Crystal Ball

Notes

• The Lucky Foot item increases the payout chance from 35% to 54%.
• Unlike the Slot Machine, the chances of the Fortune Teller machine are unaffected by playing on hard mode.
• When Fortune Teller machines are blown up, they have the same drop table as Slot Machines (see above).

Blood Donation Machine

Bumping into the machine will damage Isaac. 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 Bag or an IV Bag. 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 Scapular 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 Heart, the machine can be used without taking any damage.
• Holy Mantle 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. There is a 1% chance to spawn one of the following items instead: Mom's Underwear, Mom's Heels, Mom's Lipstick, Mom's Bra, Mom's Pad, Mom's Eyeshadow, Mom's Contacts, Mom's Wig, Mom's Perfume or Mom's Pearls. Items that have already been generated and/or collected can be spawned again in this manner.

Mom's Dressing Table is based on this Steam Workshop mod by Sinsthar.
