Vaults are special rooms that contain a variety of pickups/chests (or occasional lack thereof). Vaults require two keys to be opened, unlike most other special rooms. For a Vault to spawn, the following has to happen.
- An Arcade has to be able to spawn that floor. This requires that both:
- Once the game determines an Arcade will spawn, a Vault has a 1/10 chance to replace that Arcade. This chance increases to 4/10 if Isaac has two or more keys.

Notes[edit | edit source]
- The texture Vaults use for their rooms are the same as The Chest.
- Dad's Key, Get out of Jail Free Card, and Mr. ME! open Vaults in one use, despite the fact that they require two keys.
- Many vaults contain locked chests or key blocks, further increasing the required number of keys to fully utilize them. Make sure you have enough keys if you choose to enter one.
- Due to how Vault generation works, a floor cannot have both an Arcade and Vault on it; they are mutually exclusive.
- If an Arcade is especially valuable to your run, it may be worth limiting your keys to one going into a floor with an Arcade on it to reduce the chances of it becoming a vault.
