What the game is

How beginners improve quickly

Where the name "Turtle Soup" comes from

The name comes from a classic riddle: a man orders turtle soup at a restaurant, takes a single sip, and then ends his own life. On the surface it makes no sense at all, but once you ask the right questions the hidden backstory falls into place. That puzzle became so iconic that people started using "Turtle Soup" as a label for the whole genre of strange, hidden-context mysteries you solve by asking questions.

Around the world the same format has different names. In English it is usually called a situation puzzle, a lateral thinking puzzle, or a yes/no riddle; in Japanese it is "ウミガメのスープ". The wording changes, but the core is identical: you reconstruct the truth one question at a time.

How a round of Turtle Soup works

Every puzzle opens with a "surface" — a short scenario that looks bizarre or contradictory. Instead of guessing the ending outright, you ask questions that the host can answer with yes, no, or irrelevant. In Turtle Noir that host is an AI that knows the full solution, so it can keep answering consistently no matter which angle you take.

Each answer rules out wrong paths and sharpens your picture of who did what and why, until you uncover the hidden truth. If you want the exact questioning rules first, read the full rules guide; if you would rather jump in, browse the puzzle library and pick a case that grabs you.

Tips for your first few puzzles

New players improve fastest by starting with easy puzzles to learn the rhythm of spotting the odd detail and testing one idea at a time. Once that feels natural, move on to the highest-rated puzzles for cleaner, more surprising twists. You can play solo against the AI host or share a room with friends — no full table of people required.

The Soprano's Last Encore

It was a grotesque private show in the basement of an exclusive club. There were no actors on the stage—only a feral, disheveled woman bound by heavy leather straps, and three mute children kneeling beside her in burlap sacks. The wealthy patrons sipped their brandy, placing bets on exactly when the madwoman would snap and tear the small, living things beside her to pieces. As the night wore on and the children remained perfectly still, the bored audience grew restless. They began hurling heavy crystal glasses and shattered bottles at the stage to speed up the bloodshed. The woman let out a guttural, beastly roar. Her eyes locked onto the flying glass, and with a violent surge, she snapped the thick leather straps binding her wrists. Before a single patron could scream or flee, she made a sudden movement that cost every man in the room his bet. She died amidst the bloody wreckage, frozen in that final posture.

The Final Hiding Spot

I found the perfect hiding spot during our Halloween game in the abandoned manor. It's been hours, the air is getting stale, and I've just realized that the 'prop' I climbed into has a working lock on the outside.

Filthy Habits

I shriek with ecstasy as I wallow in the brown mire, letting the sludge coat my skin. My parents loom over me, watching. They are massive, and they are definitely not human, but I know they love me.

Family Dinner

Day 1: The woman claiming to be my mother slammed a plate of wet, grey meat on the table. I refused to eat. Her jaw unhinged with a sickening crack, and she screamed until I swallowed a bite. Day 2: I tried to sneak out while 'Dad' was in the garage. The little girl who calls me 'brother' found me. She didn't scream. She just giggled, pointing a long, pale finger back at my room. 'Not ripe yet,' she whispered. Day 3: I can hear them sharpening knives in the kitchen. They are arguing over which parts to roast. I am shaking so hard my teeth act like a metronome in the silence. Day 4: The table is finally set. The main course is steaming in the center, perfectly charred. Watching the family tear into the meat and lap up the dark red sauce, I stop shaking. For the first time in days, I feel completely weightless and at peace.

The Master's Medium

After the funeral, a crate arrived from my mentor's estate with a note: 'Only you have the touch to wield this true vitality.' Inside lay a canvas labeled 'Prima Neve' that felt uncomfortably warm, almost feverish, under my fingertips. I uncapped the tube of Venetian Red, hit by a wave of metallic scent—like wet copper coins—rather than oil. Hesitant, I dipped the unusually humid bristles of the brush and applied a single, heavy stroke. The canvas didn't just take the paint; it shuddered. The red didn't dry on the surface; it was aggressively sucked down into the grain, spreading like a blooming bruise.

The Late Night Order

I smiled groggily when I heard the delivery driver say, "Here's your food," and a voice from the hallway replied, "Thanks, looks great." But as the deadbolt slid home, I stopped breathing and pulled the duvet over my head, tears streaming down my face in silence.

Three Minutes of Darkness

The storm washed out the only bridge, trapping five strangers at the Blackwood Motor Inn—a rotting structure clinging to a cliffside, run by a single, dead-eyed clerk. On the first night, the man in Room 302 vanished. The door was chained from the inside, the windows painted shut, and his luggage sat untouched on the bed. The clerk simply stared at the rain and whispered, "The hollow only takes those who are ready." On the second night, the girl in Room 204 disappeared. Another perfect locked room. Her clothes were still in the closet. The only anomaly was a small, dried reddish-brown smear on the floorboards. Paranoia set in. The survivors barricaded themselves in, too terrified to sleep. They soon noticed a chilling detail: every night at the stroke of midnight, the grandfather clock in the lobby stopped ticking, and the motel's power died for exactly three minutes. On the third night, a third guest evaporated into the dark. When state troopers finally cleared the road, they found the apathetic clerk in the lobby, two traumatized guests locked in a pantry, and two corpses in the flooded basement. The other three people were wiped from the face of the earth, never to be found. What happened during those three minutes of darkness, and who are the bodies in the basement?

The Holy Pilgrimage

Our champion struck down the beast, yet the village still mourned its missing children. As our carriage departed, Marcus—a man with a dark, unspeakable past—sat next to our pious Holy Leader and suddenly began to tremble in terror. I met Marcus's eyes, understood instantly, and silently shook my head. I calmly handed our Leader a breath mint. I know our true leader is already a rotting corpse, but our holy pilgrimage must continue. What happened?

The Keeper

He kept me locked in the basement, bringing me food and water every single day. I screamed and begged for someone to save me, but no one ever believed my cries. Yet, when I finally watched him collapse lifeless onto the floor, I didn't feel the joy of freedom—only absolute despair.
