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 put in a specific seed after pressing the "Seed: Random" text to remove the "Random" text, then inputting a seed number between -2147483615 and 2147483615. In Endless Mode - Random, the player can input a custom seed, regardless if they have completed Hide-and-Seek or not.
In V0.1, it was possible to enter a seed number lower than -2147483615 and higher than 2147483615. Inputting the seed outside the range would crash the game.
Prior to V0.1.3, playing the game with the seed - would crash the game, but since this version, it will generate a random seed.
In V0.3.4, only one seed (1243259247) was found that seems to be impossible to beat as there was no way to exit the cafeteria in this seed unless using Dangerous Teleporters, as the cafeteria is separate from the map itself. However, there was one swinging door, but it collided with another faculty door. It could be a bug that causes the map to generate improperly.
On Floor 1, prior to V0.3, the seed 767676767 had all five notebooks close enough to Baldi that it was possible to beat Floor 1 without triggering him.
In V0.3.5, it was impossible to paste copied seeds in the custom seed input.
Since V0.3.6, pasting the seed only works if copied text only consists of numbers or a dash (only the first character) and the number must be in the valid range.
