Arcade

Arcades are special rooms that can only spawn on an even-numbered floor (Basement II, Caves II, Depths II, Womb II) if you have 5 coins or more when you leave the previous floor. Arcades require one coin to be opened. They can be replaced with a Vault if Isaac is carrying two keys or more.

• Arcades cannot spawn on XL floors.
  • Unless it is on an alt path floor.

Trivia

• The posters that can appear on the arcade's walls are pictures of games that Edmund McMillen has worked on, such as Gish, Super Meat Boy, and Time Fcuk.
• In the original Binding of Isaac, the arcade's icon was a 6-sided dice. In Rebirth, this icon was changed to a joystick.
