About
Welcome to Micro Mystery Investigator, the ultimate deduction challenge for fans of logic puzzles and classic detective fiction. Put away your revolver—your sharpest weapon here is your mind.
Forget scripted stories that you play once and forget. MMI is an engine of infinite mystery. Every time you hit "Start Investigation," the game procedurally generates a complex web of suspects, alibis, motives, and physical evidence. Your task is simple yet demanding: sift through the noise, find the contradictions, and pin the crime on the one person who fits the facts.
The game is built on pure logic elimination (similar to Einstein's Riddle or Logic Grid puzzles), wrapped in a gritty noir atmosphere.
ANALYZE: Read the generated clues. "The perpetrator was seen with red hair.", "A footprint of size 42 was found in the mud."
ELIMINATE: Does Suspect #3 have black hair? They are innocent. Cross them off.
SOLVE: Once you have eliminated the impossible, whatever remains—however improbable—must be the truth.
🕵️ Infinite Replayability: Powered by an advanced procedural generation algorithm. Solve 10 different types of crimes, including Murder, Arson, Kidnapping, Poisoning, and Espionage. No two cases are ever the same.
🧠 100% Logic, 0% Guessing: Every case is mathematically solvable. You don't need luck. You need attention to detail.
⚙️ Adjustable Difficulty: Finding the suspects too careless? Switch to Hard Mode in the settings. This removes direct name-drops and relies entirely on ambiguous evidence, putting your true deductive skills to the test.
⏳ Play At Your Own Pace: Hate ticking clocks? No problem. You can completely disable the case timer in the System Configuration menu (just set it to 0) and investigate without any pressure.
🕯️ Atmospheric Noir Style: An immersive text-based interface with a retro color palette and dynamic weather descriptions, designed to evoke the mood of a detective’s personal terminal.
☕ The Perfect "Coffee Break" Game: Solved a case in 5 minutes? Great. Have an hour to kill? Solve ten more.
🚩 Red Herrings: Watch out for irrelevant details. Not every clue points to the culprit—some are just the noise of the city.
🏆 Rise Through the Ranks: The game tracks your career. Start as a Rookie and solve enough cases to become a Chief Inspector. Can you maintain a perfect record?
💡 IMMERSION TIP: Shut out the distractions of the outside world. Press F11 to switch to Fullscreen Mode and focus purely on the evidence.
Just one more case, Detective. The precinct is waiting.

It's a nice little game, simple and effective. But... there isn't much of a challenge. I've done 21 games (won 20 and lost 1 (only cos I pressed Enter accidentally)) it basically gives you the answer in every game. But, for what it is, it's a fun little game.
I really like the idea behind this game. Infinite detective cases, text‑based, simple and clean. It’s exactly the kind of concept I enjoy, and the developer is active and reads the discussions, which is always nice to see. But after spending time with it, I ran into several technical issues that make it hard to recommend right now. The whole game runs inside a Windows terminal window, and that choice creates limitations that can’t really be worked around. On Windows 10, the screen flickers constantly. The developer updated the requirements to Windows 11, which is fair, but still surprising for a text‑only game. Even on Windows 11, long cases don’t fit on the screen. There’s no scrolling, and the terminal doesn’t offer any reliable way to view the full text. Large cases (7–10 suspects) simply get cut off, and there’s no way to read the whole page. There’s also no way to save a case and come back later, which makes the longer ones difficult to play in one sitting. No accessibility options either, no anti‑blur, and no comfortable way to read long evidence lists. I reported all of this in detail. I would have been completely fine with a simple acknowledgement like “these are terminal limitations and won’t change”, but the only answers I received were workarounds (zooming out, lowering the number of suspects), which don’t solve the core issue. And after that, the developer asked for a review. So here it is. The idea is great, and the developer clearly cares, but the terminal structure holds the whole game back. At the moment, it’s only comfortable to play if you’re on Windows 11 and you avoid the larger cases. In its current state, I can’t recommend it and I finally asked for a refund.
As a fan of "Clue"/"Cluedo", I found this game to be extremely entertaining, because it reminded me of forensic video games, such as "Criminal Case" and Disney's "Guilty Party". I also was involved with some suggestions in my own that the creator agreed with, which made me feel even more special to be a part of the creative process of this game. Despite the normal cases being easy with only one clue that singles out the culprit from the innocent suspects, I would still definitely recommend this game to anyone who loves following clues, search for alibis, comparing the evidence to suspects' profiles, and the rush of finding the culprit.
