Welcome to part 8 of our walkthrough for Deep Sleep: Labyrinth of the Forsaken. We’ve defeated the Spider Queen and unlocked a powerful new weapon for our arsenal. Now it’s time to check out The Lucky Casino and The Doll House.
These zones contain two more bosses, and a powerful new weapon for Amy to collect.
For more information about Deep Sleep: Labyrinth of the Forsaken, check out their official website here.
The rooms and items in these levels are randomized. The layout for you may not be the same as in this walkthrough. The puzzles and general progression route, however, will remain the same.

The Lucky Casino

We’ll start with The Lucky Casino, as it is the easier of the two zones.
Joshua Needs Some Help

As you wake up in the Lucky Casino, you’ll find Joshua waiting outside the building. Speak with him.

He’ll explain that he was kicked out of the casino while investigating suspicious activities. Run through the dialogue and he’ll hand you a tape recorder to gather information.

Go inside the casino. In the main room, you’ll see two vending machines. There’s also a signboard with a horseshoe on the top left side of the room that you can inspect.
There are three exits here, not counting the elevator: north, east, and west. Head north first.

You’ll see a cutscene of the Trio De Sirens performing on stage. You’ll learn that to meet the Trio face-to-face, you need to collect three golden chips.
Once the cutscene ends, head back to the elevator room and take the eastern door.

Inside, you’ll find Dr. Shulzer. Run through the dialogue and loot the three containers in the room. We found Nailed Planks, a Coin, and Batteries.

Return to the elevator room and use the Coin on the red vending machine. Amelia will note that something is stuck inside. Use the screwdriver on the vending machine to get the Jade Coin.

Next, use the screwdriver on the signboard with the horseshoe to collect a Decorative Horseshoe.

Head to the western room next. You’ll arrive at the casino’s game room. Talk to the Casino Manager sitting behind the bar. Run through the dialogue and learn that you’ll need to win three games at the casino to collect three golden chips. This will give you access to the Trio.

The Casino Manager will also give you a Whiskey and some Casino Chips in exchange for one Coin each.

Talk to the different guests in the game room. Most will only display a speech bubble, but one NPC called the Angry Guest can be spoken to directly. He mentions that he has already won a golden chip, meaning you’ll need to find a way to get it from him.

While most of the guests will tell you that they are enjoying their time at the casino, three guests in the room have negative dialgoues. Combine the tape recorder with the Batteries in your inventory, then use it on these three NPCs to get their testimonies.

Once you have all three testimonies, go outside the casino and hand the tape recorder to Joshua. He’ll reward you with Loaded Dice, warning you that he was kicked out of the casino for using them.
Getting Three Golden Chips

To collect three golden chips, you’ll need to win three games in the casino. Return to the main stage of the casino and talk to the NPC on the right side of the room. Give him the bottle of Whiskey and he’ll hand you a Four-Leaf Clover.

With the Clover in your inventory, return to the game room and use your Casino Chips at the Roulette Table. Thanks to the Clover, you’ll win, earning your first golden chip.

Next, return to Dr. Shulzer and ask him how to win the casino games. He’ll tell you that he rigged one of the slot machines.

Head back to the game room and interact with the blue slot machine in the middle. This triggers a puzzle interface. To win, line up three stars. You’ll earn your second golden chip.

For the final chip, talk to the Angry Guest next to the Craps Table. Give him the Loaded Dice.

Exit the room. He’ll be caught cheating and thrown out of the casino. But he’ll drop his golden chip. Go back to the game room and pick it up to complete your set.
Defeating Trio De Sirens

Once you have all three golden chips, talk to the Casino Manager. He’ll grant you an audience with the Sirens.

Return to the main stage and use the Coffee Pot to restore your Focus. You’ll be heading into a boss fight next, so we recommend bringing a Chainsaw for this battle.

Go through the door at the back of the stage to find the Trio waiting for you. Run through the dialogue and the fight will begin.

The three sisters hit like a truck, and the middle sister can also heal the group. Focus on her first or she’ll keep healing the enemies back to full.
The Chainsaw is particularly effective in this fight, as its cleave damage applies bleed to the other sisters as well.

After defeating the Trio De Sirens, a portal will appear in the room. Use it to return to the real world.
The Doll House

The Doll House at the end of The Attic is our next destination. Inside, you’ll find a powerful weapon similar to the Chainsaw, but you’ll need a Coin to reach the boss. Make sure you’ve unlocked the upgrade for it before starting the chapter.
The Sledgehammer and Mirrored Amy

You’ll wake up surrounded by an army of mannequins. Don’t worry, they won’t attack you. There are two boxes and a bag in this room that you can loot for items.
There are three exits in this room: north, east, and southwest. Take the eastern exit from here.

In the next room, you’ll find some Painkillers on a table. There’s a door leading further east, but it’s locked for now.

You’ll also notice something hidden under a cloth. Interact with it to reveal a fortune-telling machine. Run through the dialogue with Bert, The Misfortune Teller.

There’s a vending machine next to the fortune teller. Imagine a Coin and use it with the machine to get a Toy Capsule.


Examine the Toy Capsule in your inventory and press the middle button to get a Golden Key.

Use the Golden Key on the locked door to go inside.

You’ll arrive in a room with three large mirrors. Approach the mirror on the right.

A short cutscene will play as a mirrored version of Amy steps out and attacks you.

This mirrored Amy deals heavy damage and attacks relentlessly. Defeat her to obtain the Sledgehammer.

Like the Chainsaw, the Sledgehammer has a cleave attack, but instead of bleed, it applies slow. She also drops an Amy Mask
Creepy Joshua Encounter

Return to the room with the mannequins and take the northern exit. You’ll arrive in a small room with Joshua standing near the windows. There’s a chalkboard next to him and a Coffee Pot on the table nearby.

Talk to Joshua and run through the dialogue. He’ll mention a headache and ask for some Painkillers.
Give him the Painkillers. He’ll continue to complain and then ask you to help him take his glasses off.

Agree to remove the glasses. His entire face will come off, revealing that it was a mask all along.

This will trigger a fight against a Suited Mannequin. Defeat the enemy and check the body to obtain a Puppet Crossbar.

Next, check the chalkboard to collect a Photograph. Use the Coffee Pot if you need to restore Focus, then return to the room with the mannequins from earlier. From here, take the southwestern exit.
The Puppetmaster Puzzle

You’ll arrive in a large room with six mannequins standing in strange poses. All of them have strings attached. In the middle of the room, there are three strings you can interact with. The northern door is barred for now.

Before doing anything, check the door leading southeast.

This takes you out onto the roof. You’ll spot a bag on the drainpipe.

As you approach it, the shingles on the roof start to collapse. Don’t worry, you won’t fall.
Loot the bag for an item, then head back inside.

Now use the Puppet Crossbar you picked up earlier on the strings in the middle of the room. This will let you change the poses of the mannequins.

Examine the Photograph you collected from the chalkboard earlier. It shows the correct pose you need to recreate in order to unlock the northern path.

Each of the three strings affects two mannequins at once. Adjust the poses until they match the photograph.

Once you’ve set them correctly, the northern passage will open. Head into the next room.
Defeating the Puppet Master

You’ll find yourself in a small corridor. Head through the northern door.

The Puppet Master is waiting for you in a small room.

Run through the dialogue and he will summon three mannequins for you to fight. Defeat the three mannequins, and the boss battle against the Puppet Master will begin.

Like the Spider Queen, the Puppet Master also summons minions to shield him and keep you occupied.

Both the Chainsaw and Sledgehammer are excellent weapons for this fight. The Sledgehammer can delay enemy turns with its slow effect, while the Chainsaw can apply bleed to both the minions and the Puppet Master.

After defeating the boss, a portal will open. Use it to return to the real world.
