I get to use my imagination in the backrooms, so here are some stuff I made

Room 651

Room 651 is the 652nd room in the backrooms, featuring a more lush, greenier variant of room 0. Dividing 7 by 651 gives you 93, and the 93 is obtained when you add 7, 18, 5, 5, 14, 13, 1, 26, and 5 together. This spells out “Greenmaze”. This is referencing Hollow Knight, as the music played here is a slowed down, distorted, creepier version of the greenpath ost.

Room 3,260

Room 3,260 is the 3,261st room in the backrooms. It is a bigger brighter version of the 8th level of the backrooms. If you divide 3260 by 20, you get 163. The 163 is obtained when you add 20, 8, 5, 20, 18, 21, 5, 1, 2, 25, 19, and 19 together. This spells out “The true abyss”, which references Hollow Knight’s abyss. The music played down here is the abyss’ ost, but slowed down.

Room 2,140

Room 2,140 is the 2,141st room in the backrooms. It is a dark forest, much like room 651. Dividing 20 by 2140 gives you 107. This 107 is obtained when you add 20, 8, 5, 19, 21, 2, 3, 15 and 14 together. This gives you “the subcon”, which references a hat in time. The music that is played is subcon forest’s ost but creepier.

Room 20,000,000

Room 20,000,000 is the 20,000,001st room in the backrooms. It is a giant room with a square layout while a turtle sings in persian (link here). This is a reference to the “Persian turtle” meme, as T in an A1Z26 Cypher is 20, and there are 6 extra 0’s, as the word “Turtle” has 6 letters in it.

Room -48

Room -48 is the -49th room in the backrooms. It is a tundra with a cabin (Much like Tirsiak’s starting room), but mirrored. It was chosen as -48, as she is the 4th unknown specimen and the - acts as a mirror.

Room 30,008

Room 30,008 is the 30,009th room in the backrooms, featuring an Unlimited Ickea. It is a play on words, as the Ickea is spelled comically incorrect, as the real name is “Ikea”. This is also a reference to the 3,008th SCP, taking the form of said Ikea.

Room 292,439,477

Room 292,439,477 is the 292,439,478th room in the backrooms, taking the form of a metro. This is because the map is based on Phantom Forces’ metro map, as it’s the most iconic one of them all.

Room 444

Room 444 is the 445th room in the backrooms, taking the form of a claustrophobic trench system full of spiders. This place is darker than level 8. Dividing 4 by 444 gives you 111. By using A1Z26 Cypher, you get 4, 5, 5, 16, 5, 18, 14, 5, 19 and 20. Converting this gives you the term “Deepernest”, which is a reference to Hollow Knight’s Deepnest. The ost is Deepnest’s but it is somehow creepier. There are also 2 references to 2 games; a poster for Nyakuza Metro from “A Hat In Time”, and a poster of Embry, the main character you play as in the Indie game “It’s Not Me, It’s My Basement”

Room 297.18

Room 297.18 is the 297.19th room in the backrooms. It features a Russian battlefield from the 1940's. The 297.18 is the product of the equation 7.62x39. This is the caliber of the AK-47. The ost here is a distorted version of Fort tundra's free time

Room 3105

Room 3105 is the 3106th room in the backrooms, taking the form of mutated sewers. Dividing 23 by 3105 will give you 135. Using A1Z26 cypher, you get 23, 1, 20, 5, 18, 23, 1, 25, and 9. Converting this gives you the word "Waterways". This, of course, references Hollow Knight's royal waterways. The music isn't like any other ones. The music is a more melancholic version of royal waterways' ost.

Room 216.84

Room 216.84 is the 216.85th room in the backrooms, which takes form of an American military camp. This is because the number is the product of 5.56x39, which is the standard American military caliber. This is also backed up by the fact the ost played here is K.A.P.O.W Camp's Free time ost but it's reversed.

Room 7,000

Room 7,000 is the 7,001st room in the backrooms, this takes form of an abandoned prison. Said prison closely resembles the one in The Escapists, or Stalag Flucht. The ost here is stalag flucht's. This is also backed up by the fact that the original number was 70 (as Stalag Flucht is the 2nd prison in the escapists). Using A1Z26 Cypher, you get 6, 12, 21, 3, 8, and 20. Converting this gives you the word "Flucht".
