Every play, a brand new crime.
microCrime is a Roll-and-Write investigation game for 1 or more players. You are the detective — and you need to solve the case. It features intriguing mechanics, ever-changing scenarios, a detailed Rulebook and tables. It's endless and ever-changing.
Close the Case
A murder has been committed. Evidence must be gathered, leads followed, and the truth reconstructed from nothing. This is a real investigation — built on proof, deduction, and the occasional leap of intuition. The case won't close itself. That's your job.
Your Space. Their Crime
Pick any room. Your kitchen. Your bedroom. The garage. The moment the game begins, that space is no longer yours — it's a crime scene. Walk through it slowly. Look at it differently. Every corner, every object, every connection to the next room is part of the case. You're not at home anymore. You're inside the investigation.
Everything Is Evidence
Your phone. Your coffee mug. The book on the shelf. In microCrime, anything in the room can become evidence — and everything must be treated as if it belongs to the case, not to your life. The game hands you a framework; the real world fills it with detail.
No Right Way to Play
There's no single right way to play microCrime. Some approach it as a Roll-and-Write. Others as a board game, an RPG, a LARP, a deduction puzzle, or an escape room. Most end up mixing all of the above — and that's exactly the point. The Rulebook gives you the tools. What you build with them is entirely up to you.
Two Acts. One Truth
A microCrime session unfolds in two acts. First: the crime scene inspection, where players roll dice and record every case element in the Case File — the weapon, the witnesses, the timeline. Then: the investigation, where dice are set aside and discussion takes over. Detectives debate, argue, and piece together a story that answers the six questions at the heart of every case — How, What, When, Where, Why, Who. The game ends when everyone agrees on a reconstruction. Close the case. Write it down. It's done.
Three Documents. Infinite Cases
microCrime is delivered as three PDF documents — print them, or load them on a tablet and go paperless. The Rulebook (24 pages) covers standard and advanced rules, plus all the tables you'll need. The Case File is your dossier — fill it in as the investigation unfolds. The Evidence Tokens are printable tags to place on real objects in your crime scene. Everything is designed to put you at the center of the game from the first page.
A Die. A Pen. That's It
A six-sided die. A pen. That's it. No investigation experience, no improvisation skills required. microCrime is a case generator — every session produces a completely new crime, shaped by dice rolls and the story your group builds around them. Play it once. Play it a hundred times. The case will always be different.
The Rulebook
The Rulebook contains standard rules and advanced rules for experts. Plus, several tables and indications on how to roll dice and get different results, each described in detail. Using these rules and tables players will create a brand new crime every time.
The Case File
A collection of sheets where players can write their story on. It consists of different pages, like a real dossier, and players can fill it properly by writing every detail they come up with or suggested by the game itself.
Evidence Tokens
Tokens that can be printed, cut out and folded to be used in the crime scene — on real objects and evidences.
This page collects amendments to the rules. When revised, the version number is incremented and new updates are highlighted.
Commentary from the game designer to clarify and expand on rare and complex rules. New updates are highlighted when the document is revised.
Evidence Tags inspired by microCrime! The game gave inspiration to Banana Mustang for this item: use everyday objects around your house as evidence to solve the mystery of the crime scene — which becomes any room you set it up in. Download and 3D print them as props for the game.

It feels like I just started this KS adventure yesterday. Yet, it's already ended. The campaign was thrilling — every morning I rushed to check the number of backers, read the comments, feel the vibe. It's been a hell of a ride. One I'll never truly forget.
I didn't just find backers — I found awesome people who decided to share their time and kind words. We were all in this together. You and me.
