some of these codes are cyclically randomly generated every 15 or so minutes, and some are fixed. however, with only one exception (im pretty sure), each of the randomly generated codes are the same when a server is created. with these codes, ill add (RG) at the end (this is not a guide of how to obtain said RG codes, if you want more information on that see https://roblox.fandom.com/wiki/Community:Bobbysayhi/Be_Crushed_by_a_Speeding_Wall)
code behind the wall: 2015 (RG)
big black door room: 7845 (RG)
owner id room: 641139
neon room: 1234 (RG)
description room: 1112
room with armour man: 31099
binary/LEET room: 1337
scattered number kitchen/block room: ive huddled these two together because theyre not a case of inputting a code. one is the numbers are scattered across the room (see prior link to see where those numbers are) and one doesnt have a code at all
four statues room: 5021
maze room: 3033 (RG)
face room: this ones weird because it doesn't cyclically randomly generate like all the other randomly generated codes, and also it isn't the same when the server is created. you just kinda have to check what it is before doing runs of 12 secret trials
parkour room: no code (duhh its parkour)
