Description

The Room: Old Sins is widely regarded as the strongest and most playable entry in The Room series. Its chilling look hides a secret box filled with clever puzzles, and the mix of eerie visuals and inventive challenges creates an experience you won't forget. On top of that, spine-tingling stories wait in every hidden room to keep you on edge.

WAS THIS HUNT A TREASURE WAR?

The puzzles are the stepping stones on your ambitious hunt. The adventure opens with the deeply bizarre disappearance of an engineer named Edward and his devoted wife. Their family belonged to the Kingdom's upper class and was long known for its enormous wealth. That very fortune awakens your greedy, darker side, and whatever awaits, you'll seize the opportunity one night. Follow the trail to Waldegrave Manor.

HAUNTED DOLL'S HOUSE IN THE ATTIC

Yet the trail eventually leads you to an old attic. From the outside it looks completely ordinary, but once you step inside, a horror movie unfolds right before your eyes. This is really a dollhouse crammed with bizarre objects. Around it lie notes left behind by the couple as clues, containing spiritual reflections on the fate of their lives.

THE QUEST FOR CLUES

Your puzzle-solving quest officially begins once you explore the horror dollhouse. Many strange objects here differ in shape and material, and each serves as a clue to the answer hidden in the puzzle box. Gather and examine every fragment you come across, since some will reveal shocking secrets while others become pieces of a larger jigsaw. Each clue links to the others, so don't rush to discard anything after reading it!

NEWLY DESIGNED HINT TABLE

Old Sins is known for the toughest puzzle boxes in The Room series. When you reach the higher levels, where the challenges are steep and the clues seem to lead nowhere, don't give up in a hurry. We support you with several hint packages. To keep you from relying on them too heavily, hints only appear after waiting a short period and cannot be viewed twice.

CLUES THAT TIGHTLY BIND TOGETHER

The attic dollhouse is divided into several small rooms, and you can move freely between them to find the quickest answer to each puzzle. Items and events in one room often help another, such as water boiled in the kitchen producing steam that is needed elsewhere. Puzzles in one room may connect to another, which means clues across different locations are closely intertwined.

LEAVING THE SECRET ROOM AFTER RECEIVING THE REWARD

If the sequence of puzzles in each room starts to feel repetitive, Old Sins offers a fresh atmosphere just for you. Puzzle boxes are scattered throughout the rooms, and several rooms can be unlocked at once. Moreover, once you finish the puzzle in any room and claim the final loot, you cannot step back inside, because Null has taken hold of it.

Return to the notes Abigail, the wife, left in the secret house. She explained that Null is a bizarre material capable of warping entities in reality. The engineer was deeply enthusiastic about learning and researching it. However, Null was actually controlling him. Realizing this, his wife tried to find a way to pull him free, so she hid Null inside the horror dollhouse and fled.

NULL CONTROLS THE WEALTHY ENGINEER

After his wife left, Edward frantically searched for her and for the strange material Null. Yet he never left the Manor; he merely wandered between the attic and the estate. The truth is that Null held him in a daily cycle he could not escape. Eventually Edward uncovered the truth too, but by then it was too late, and he accepted that Null would take his life.

PLAYER IDENTITY UNLOCKED

Finding Edward and a Null fragment reveals a secret about your true identity. At this point, you can see that the player has completed the assigned task. You are a member of Circle, an organization dedicated to uncovering the world's horrifying secrets. Old Sins offers quests involving Null materials, where you secretly search for and assemble puzzle pieces everywhere.
