Parlor Games:
Ephemera Engine

A system for unrepeatable social games that privilege human interaction, creative contribution, and the residue of an evening that can never be reconstructed.

We gather more and connect less.

The U.S. Surgeon General declared loneliness an epidemic. Gen Z and Millennials are reviving the dinner party as a cultural response to digital fatigue. The market for meaningful in-person experiences is exploding.

Three phases. One unforgettable evening.

Every Ephemera Engine game follows a ritual arc: preparation builds anticipation, game night creates connection, and artifacts preserve the memory.

The Confession Album

A chain-answering game built on the Victorian confession album tradition that Marcel Proust made famous at age thirteen. Questions are displayed on a physical board. Each player inherits the previous player's question, then chooses a new one from the diminishing board.

The game appears to be about answering questions. It is actually about choosing them.

Structured, escalating, reciprocal self-disclosure produces measurable closeness. — Aron et al., 1997

Murder Mystery

A fully immersive whodunit where pre-game transforms guests into characters weeks before the party. Unlike commercial murder mystery kits, this system generates unique scenarios from combinatorial seeds and deeply involves guests in world-building.

"The Alhambra is dressed for an occasion. Gardenias float in cut-glass bowls. The piano has been tuned twice. By midnight, the gardenias will have wilted and Cora Delacroix will be dead in her chair..."

Whose Memory?

An intimate storytelling game where anonymous personal stories become the medium for knowing each other more deeply. Players submit true stories on a theme before the party; during the evening, the group reads, discusses, and tries to match each story to its author.

The game surface is simple. The depth comes from the stories people choose to tell, the assumptions the group makes, and the conversations that follow the reveal.

A game about perception, intimacy, and the distance between who we are and who others think we are.

The Exquisite Corpse

A collaborative fiction game where players contribute fragments — sentences, images, lines of dialogue — then assemble them into narratives using structural templates. Honoring the Surrealist parlor game that produced "The exquisite corpse shall drink the new wine."

Four rounds: Story Spine, Exquisite Corpse, Cut-Up, Rewrite. The constraint of random fragments forced into fixed structures produces surprising, often beautiful narratives from collision.

The most collaborative game in the series and the least vulnerable — a natural complement to the other three.

Beautiful keepsakes from unrepeatable evenings.

Every game produces physical and digital artifacts: albums, dossiers, zines, and personal letters. Generated from HTML/CSS templates, rendered as typographically beautiful PDFs. A confession album that looks like a database has confessed nothing.

No one does all three phases.

Existing products cover entertainment or intimacy, but none combine pre-game anticipation, screen-dark game night, and beautiful post-game artifacts.
