CrimeKey: Murder Logic

CrimeKey: Murder Logic is a mystery, logic, and deduction game where every criminal case is solved using your brain, not luck.

Investigate murder scenes, analyze clues, eliminate suspects, and find the correct combination of culprit, weapon, and location. Each case functions as a reasoning challenge: you'll have a deduction grid where you can mark possibilities, cross out impossible options, and confirm your conclusions until you uncover the key to the crime.

If you enjoy logic games, detective cases, murder mysteries, deductive riddles, and investigative puzzles, CrimeKey is for you.

Solve each case step by step.
In each level, you'll find a new mystery with several interconnected elements:
Suspects
Weapons
Locations
Clues
A single solution
Your mission is to cross-reference the available information and find out what really happened. Some clues will eliminate options. Others will help you connect characters, objects, and settings. Little by little, the case will take shape… if you know how to look closely.

A Grid for Thinking Like a Detective

CrimeKey uses clear and classic logic deduction mechanics. Mark discarded possibilities with an X and use a confirmation mark when you're sure of a connection.

There are no reflexes, no rushing, and no luck involved. Pure logic reigns supreme: observe, compare, eliminate, and solve. Like the good old-fashioned paper games, but adapted for mobile.

Mystery, Logic, and Murder Cases

Each case is designed so you can solve it through reasoning. You don't need outside knowledge or to guess the answer. All the clues make sense within the case and lead you to a final solution.
