Seeds are the mechanism used to randomly generate floors.



The seed number on the elevator screen.

A seed is a random string of numbers used in level-generating algorithms to procedurally generate and create each floor in Baldi's Basics Plus. After completing the Hide-and-Seek mode once, the Player can choose to put in a specific seed or leave it blank to generate a random one. In Endless Mode's random option, the custom seed is available regardless of completing Hide-and-Seek.

Level-Building Algorithm Codes


Accessing the ClassBuilder.

When accessing Baldi's Basics - Challenges Demo code via DnSpy, there is an algorithm for generating all the different types of locations:



The Stealthy Challenge's seed.

  • The seed for the Stealthy Challenge is listed as 99.
  • The concept of randomly-generated floors has been inspired by the game ToeJam & Earl.
  • There are exactly 4,294,967,039 possible seeds.
  • Prior to the V0.1.1 update of Baldi's Basics Plus, it was possible to enter the seed number lower than -2147483615 and higher than 2147483615.
  • There are 4 known seeds that generate Floor 1 with 3 classrooms: 2090193694, 1430814486, 1606946751 and 334598700. This has been fixed on V0.1.4.
  • Some seeds like 1430814486 can generate a placeholder room that looks like Janitor's Closet, but bigger. Its color on the map is black like the Library prior to the V1.2 in the Kickstarter Exclusive Demo. This has also been fixed in the V0.1.4 update for Baldi's Basics Plus.
