Backrooms puzzles and rooms in Pet Simulator 99

The Backrooms can be accessed from any spawn in Pet Simulator 99. Just look for thevery spooky building and enter the door.

Once in, you’ll spawn in to aprocedurally-generated Backrooms. Every Backrooms should generate the same goodies and sites, however the order and connections will be random. You’ll be walking through seemingly endless tunnels, with many turns to get you truly lost.

Along the way, you’ll find:

Note that all new items and Pets are only available as long as the Backrooms update is live, so when the event is over,you won’t be able to get them again!

If you’re unhappy with the layout of your Backrooms, you canleave the game and rejoin it. The Backrooms you’ll enter will be a different one.

Pet Simulator 99 Backrooms Boxes

The puzzles in the Backrooms are rather simple. They mostly consist of bigger rooms withlocked doors and green buttons.You may have to partake in small obbies to find all the buttons, but once you’ve pressed them all, you’ll be able to continue.

There are somepuzzles that still have yet to be figured out. In thePet Simulator 99 Discord, the brightest minds are still trying to crack them.

Pet Simulator 99 New Pets

All new Backrooms Eggs and Pets in Pet Simulator 99

There are12 new Pets for you to find, but the different varieties of Eggs must be found deep within the Backrooms. Due to the randomised nature of the map, I can’t guide you to them directly, unfortunately.

All the new Pets from the Backrooms event are:

Like other Eggs, there is a small chance to getGolden variantsof these Backrooms Pets!

To reach the better Eggs to get the rarer Pets, you’ll need todelve super deep into the Backrooms and hope you’re lucky enough to stumble into them!

Pet Simulator 99 Backrooms Egg

There will be signs aside the Backrooms Eggs you find which will tell you how much the chance of earning the Huge Pet the Egg gives you has been boosted by.It goes all the way up to 100x, but that Egg is incredible rare…

Here are the new Eggs that I’ve been able to discover, and all the Pets you may earn from them:

Pet Simulator 99 Lucky Block Backrooms

Backrooms Nightmare Egg (costs 200 Coins):

Backrooms Gooey Egg (costs 250 Coins):

The Huge Bloo Cat and the Bloo Catcan only be obtained from purchasing the Backrooms Forever Packin the Exclusive Store, or through trading.

That covers all the new Pets in the Backrooms event for Pet Simulator 99, but that’s not all that’s been added!

How to get all new Backrooms items in Pet Simulator 99

There have been somenew items added to Pet Simulator 99, all which can be found in the Backrooms, or purchased from the Exclusive Store.

Each of these items can be found in the Backrooms. I have yet to find any of them, but they’ll be found asdrops from any of the large breakablesthat can be found as you venture deep into the Backrooms. I would imagine that you’ll have better odds of finding these behind the locked Backrooms doors.

If you spend 25 Robux on the Backrooms Pack in the Exclusive Store, you’ll get a chance toreceive any of these items. The pack resets after some days, allowing you to buy it repeatedly in case you didn’t get what you want.

How to get and use Backrooms Keys in Pet Simulator 99

The Backrooms Keys in Pet Simulator 99 can be earned in two ways, and they’llunlock the locked doors you’ll come across.

You could purchase them from the Backrooms Pack in the Exclusive Store, for 25 Robux. If you’re lucky, you’ll find one for free in that pass,so check to claim a free Backrooms Key!

The best way to get Backrooms Keys, however, is by grinding for them. There is a (very) small chance ofgetting a Backrooms Key when grinding the breakables you’ll find. After about 15 minutes of solid grinding, I was able to grab one.

I may have simply been unlucky, but they seem to be rather rare. Althoughif you have strong Pets, this grind will be reduced dramatically. It will be worth to grind for some Backrooms Keys before delving too deep into the Backrooms.

Once you’ve got a Backrooms Key, you’ll be able to unlock the locked Backrooms doors deep into the Backrooms.Behind these doors is a treasure room. You’ll either be rewarded with lots of Diamonds, or you’ll get to choose a mystery treasure. The items granted by the huge treasure chests are awesome, so I hope you get something you want!

There may be other, different treasure rooms behind the locked Backrooms doors, but I’ve yet to come across them.

There’s lots of mystery surrounding the Backrooms in Pet Simulator 99, with the rare 100x Huge Egg and the strange puzzle that players are still struggling over. I wonder what you’ll find.
