Very Easy (7)
Very Easy The Book Club
A book club's routine gathering where members are debating the latest bestseller — until someone opens a book that wasn't on the reading list, and finds something far worse than a spoiler inside.
Very Easy 24-Hour Delivery
A 24-hour delivery depot in the dead of night, shelves stacked with parcels. A worker on the graveyard shift is sorting packages when they discover one that will never be signed for — lying beside the person who last handled it.
Very Easy Netflix and Kill
A carefully planned movie night — popcorn and soda spread across the coffee table, the projector casting flickering light on every face. As the end credits roll, someone on the couch has quietly stopped breathing. The killer sat in the same row and watched the entire film with everyone else.
Very Easy Fresh Paint
A painter's studio where the canvases are still wet and the scent of turpentine hangs in the air. An unfinished painting stands on the easel — beneath it lies the person who will never complete it.
Very Easy Car Repair
A neighborhood auto repair shop, a car still dripping oil on the lift. A mechanic pops the hood for a routine check — only to discover this vehicle's problems go far beyond engine trouble.
Very Easy House Party
A house party is spilling from the living room into the dining room and kitchen, music still playing while guests search for the host. By the time someone notices a guest missing, the party has already become a crime scene.
Very Easy Outdoor Painting
An outdoor painting class has set up beside a pond, easels facing the scenery while students work in the open air. By the time the session should end, one canvas is still unfinished, and the quiet clearing has become a crime scene.
Easy (12)
Easy The Flower Store
A corner flower shop at dawn, the scent of roses and lilies mingling with something faintly sickening. Beside the most beautiful bouquet lies someone who will never smell flowers again — and the cash register hasn't been touched.
Easy The Book Kiosk
At a busy book kiosk, shoppers drift between display tables, shelves, and the walkway with paperbacks tucked under their arms. Behind the cheerful fair layout, one quiet corner hides a death that no signing queue can explain.
Easy A Horse With No Name
A sun-baked western stop sits between desert, shack, and canyon, with dust gathering around the tables, cactus patches, boulders, and one uneasy horse. Somewhere in that sparse frontier scene, an unnamed rider has left a murder for the town to solve.
Easy The Riding Lesson
Early morning at a suburban riding school, the sound of hooves echoing through the stable corridor. A riderless horse paces alone — its rider lies in the back of the stable, their final lesson one they will never dismount from.
Easy The Beach
A sun-drenched beach, umbrellas and towels scattered across white sand. The tide washes over a figure frozen at the waterline — in paradise, someone's vacation has just become permanent.
Easy The Dead Plumber
An ordinary suburban house where the owner called for repairs because of a leaky kitchen pipe. The plumber arrived with their toolbox right on schedule — but before fixing the pipe, they became the last victim inside this home.
Easy Hoarders
A hoarder's home stacked floor to ceiling — old newspapers and cardboard boxes forming a labyrinth of narrow passages. When social services finally push the door open, beneath the layers of accumulated clutter lies a deliberately hidden secret.
Easy The Great Escape
A high-walled state prison, security cameras covering every corner. An inmate has planned an elaborate escape — but when the alarms blare and guards seal every exit, they realize there's more to deal with than just a breakout attempt.
Easy The Courtroom
A solemn courtroom, the defendant's seat empty but the gallery packed. The jury is about to deliver its verdict when the gavel falls to the floor — the judge will never strike it again.
Easy Summer Isles
A chain of summer islands scattered across turquoise waters, palm trees swaying in the breeze. Resort guests are enjoying their cocktail hour — until someone discovers that in paradise, not everyone is still alive.
Easy The Backyard Garden
A meticulously maintained backyard garden, roses and tulips lined up in neat rows. A neighbor drops by to borrow a lawnmower and stumbles upon something more disturbing than weeds deep in the flowerbed — a body that shouldn't be there.
Easy A Walk in the Park
A sunny afternoon at the city park, joggers and dog-walkers and parents with strollers each going about their day. Until a runner trips over something in the bushes beside the path — an ordinary walk in the park becomes a crime scene.
Medium (11)
Medium White Wedding
A wedding hall draped in white roses, champagne flutes catching the chandelier light. The bride and groom are exchanging vows when a sharp sound comes from the back pew — someone has found a different way to make 'til death do us part' come early.
Medium Hell's Kitchen
The back kitchen of a Michelin-starred restaurant, flames roaring, knives flashing. The head chef is screaming at the line cooks — but in this hellishly busy kitchen, someone isn't just cooking up a perfect dish. They're cooking up a perfect alibi.
Medium Lakeside Cabin
A remote lakeside cabin, campfire light flickering against the window, the lake reflecting a sky full of stars. Old friends have gathered for a weekend getaway — but the neighbor across the lake notices the cabin lights stayed on all night, and on Sunday morning, only five people walk out. Six walked in.
Medium Surprise Visitors
An ordinary family's weekend afternoon, the doorbell ringing one after another. An uninvited visitor, a relative who dropped in unexpectedly, the new neighbor from down the street — and one of them brought more than a housewarming gift.
Medium Freezing Rain
A sudden freezing rainstorm has hit a small town — roads iced over, phone lines down. Inside an old house, people stranded by the weather huddle around the fireplace. When the power comes back and the de-icing trucks finally arrive, someone on the living room sofa has grown colder than the storm outside.
Medium The Barbershop
An old-town barbershop, its rotating pole spinning lazily in the afternoon sun. A few regulars are waiting their turn, mirrors reflecting every face in the room. As the barber shakes out the cape for the next customer, the scissors haven't even been picked up yet — but someone is already bleeding more than a nick.
Medium The Art School
An art school where studio lights are still on late into the night, student work scattered across every surface. The end-of-term exhibition opens tomorrow — but in front of an unsubmitted installation piece lies someone who will never pick up a brush again.
Medium Preppers
Deep in the woods, far from any town, a fully stocked underground bunker hides beneath the earth. A group of survivalists has stored years of food and ammunition — but the disaster they should have been preparing for was already inside the bunker with them.
Medium Holiday Shopping
A shopping mall on Christmas Eve — crowds surging, holiday music blaring. Every store has a line at the register, cash drawers ringing nonstop. In a fitting room deep in the discount section, someone has tried on an outfit they will never take off.
Recently Updated Medium Lake Fishing
A peaceful lake becomes the backdrop for a chilling discovery. Anglers, hikers, and dock workers each had their own story, but one of them knew more than they let on. By the time the sun set behind the pines, a body was found — and the only witness was the silent water.
Recently Updated Medium Discord Island
A gathering on Discord Island brings familiar community members into spaces named for book discussion, puzzle help, creations, and online play. When Garand is found alone with the killer, the channel map becomes the crime scene.
Hard (15)
Hard A Messy Situation
An apartment turned completely upside down — drawers yanked out, books swept off shelves, glass shattered across the floor. A burglary gone wrong? Or did someone deliberately create chaos to hide what they were really after? Among the overturned furniture and broken glass, only careful deduction can piece together the truth.
Hard The Abandoned Museum
A museum shuttered for years, its exhibits left in place beneath a thick coat of dust. An urban exploration crew sneaks in after midnight — in the dinosaur fossil hall, what they find isn't just prehistoric remains, but a body far more recent.
Hard The Commercial Square
A downtown commercial square, café umbrellas shading crowded tables, pigeons flocking around the fountain. Every shop is busy with the day's trade — but behind the rolled-down shutter of one closed store, a deal has just been settled in a way nobody wanted.
Hard Date Night
The city's hottest date-night restaurant, candlelight flickering at every table, each one set for a dressed-up couple. Waiters weave between tables balancing trays — and when dessert arrives, everyone notices one couple hasn't spoken a word since the appetizers.
Hard Grizzly Night
Night settles over a forest campsite, lanterns glowing inside the tents while the dark woods press in from every side. The group came for a quiet outdoor escape, but when a bear is spotted near the clearing, panic sends everyone running — and one camper never makes it back.
Hard The Remote Village
A remote village sits deep beyond the main road, where a general store, tavern, library, and narrow forest paths hold the whole community together. When the morning fog lifts, one villager is missing from the usual routine, and the quiet settlement starts to feel much smaller.
Hard Frontier Town
A frontier town is settling into another tense evening, with the chapel doors closed, the bank guarded, and the general store still lit against the dust outside. Somewhere between the porch chairs, horses, cactus patches, and cash register, one resident has turned the town's uneasy silence into a murder scene.
Hard River Crossing
At a rough river crossing on the frontier, wagons, horses, crates, and cliffs turn a simple passage into a dangerous choke point. When the group reaches the far bank, one traveler is missing, and the outlaw everyone feared may have used the crossing as cover.
Hard Minigolf
A sunny afternoon at the mini golf course, brightly colored obstacles scattered across the green. A group of friends tee off for a casual round — but by the final hole, someone has taken their last putt.
Hard Swimming with the Fishes
The city aquarium after closing hours, massive glass tanks glowing an eerie blue in the darkness. The night security guard does one last round — at the bottom of the shark tunnel, what they see silhouetted against the glass isn't marine life. It's someone who will never surface again.
Hard Blackout
A sudden blackout plunges an entire city block into absolute darkness — every light goes out at once. When emergency generators kick in and flashlight beams cut through the dark, the chaos reveals something chilling: someone used those six minutes of total darkness to do something that could only be understood in broad daylight.
Hard The Lisbon Book Fair
The Lisbon Book Fair on a warm afternoon, rows of white tents stretching as far as the eye can see, books from every corner of the world on display. Hundreds of readers wander between the stalls — deep in a tent of obscure crime novels, someone hasn't just opened a book. They've stumbled into a real mystery.
Hard The Hiking Trip
A scenic hiking trail winding through mountain forest, morning mist drifting between the pines. A group of hikers gathers at the trailhead cabin to check in — but the headcount after the hike reveals something unsettling: seven people set out, but only six made it to the end.
Hard The Botanical Garden
A botanical garden in full bloom, exotic plants from every continent competing for attention. The gardener makes their morning rounds through the greenhouses — in the tropical plant section, among hundreds of species, the one that turned deadly was never supposed to be growing here.
Hard The Horsetrack
The grandstand roars as horses thunder toward the finish line — odds and bets gripping every spectator's nerves. But deep in the stable area, in the quietest corner of the track, a game far darker than any race has already reached its finish.
Expert (6)
Recently Updated Expert Main Street
Main Street is busy from curb to tower, with cars, a bus, elevators, and pedestrians crossing between the park and fountain. Virgil is found alone with the killer, and every sidewalk and elevator becomes part of the reconstruction.
Expert The Movie Studio
A bustling Hollywood movie studio mid-production — sound stages blazing with light, backlot sets standing ready. The day's final scene wraps and the director calls 'cut' — but there's one actor who will never respond to direction again.
Expert The Zoo
Early morning at a sprawling city zoo, keepers beginning their daily rounds to feed the animals. Amid the hungry calls and rattling cage doors, someone in the primate section makes a grim discovery — the vet who was perfectly fine yesterday is now lying inside an unlocked enclosure.
Expert The Golf Course
A misty morning on the golf course, the fairways and greens perfectly manicured. A foursome tees off at the first hole — but by the ninth hole, someone has lost more than just a golf ball. They've lost their life.
Expert Solitary Confinement
A maximum-security prison, the iron doors of the solitary confinement wing sealed one after another. 24-hour surveillance, timed patrols, total isolation — every measure designed to keep danger locked inside. But when a guard unlocks one of those cells, they discover that solitude couldn't keep this inmate alive.
Expert Mystery Islands
A chain of mysterious islands scattered across deep blue waters, each one isolated from the next, each one bearing signs of human presence. The ferry captain gets a radio call after dropping off the last tourists — the island phones have gone dead. By the time he turns back, one island is empty, and another has more people on it than it should.
