What is a murder mystery game?
A murder mystery game hands you a crime and asks one question: who did it? The best ones give you everything you need — suspects, statements, a scene — and let you reach the answer yourself. No lucky clicks, no waiting for the detective to explain.
Four kinds of murder mystery games
Not every mystery plays the same. Here is how the main types compare, so you can pick the one that fits how you like to think.

Why logic beats luck
In a logic mystery, nothing is random. Each suspect stands in exactly one room, each statement narrows the options, and the killer is the one person who could have been alone with the victim. When you name them, you can prove it.

How to solve your first case
- 1
Read every statement
Each suspect tells you where they were — or weren't. Mark what you know.
- 2
One per row, one per column
Like sudoku: every row and every column holds exactly one suspect.
- 3
Find who was alone with the victim
The killer is the only suspect who shared a room with the victim.
