Murder Mystery Game Brand Reviews
Every major murder mystery case file brand you can actually buy in the UK, reviewed honestly — with prices in pounds and no pretending American shipping doesn't exist.
Murder mystery case file games all promise the same thing — a dossier of evidence, a killer hiding in the paperwork, and a satisfying "gotcha" when you crack it. But the brands behind them differ enormously: some are UK businesses with free Royal Mail delivery, some are American imports you can only get through Amazon, and some barely ship here at all. Print quality, difficulty, replay value and refund policies vary just as much.
Each review below covers the same essentials: what's in the box, current UK price in £, how many people it suits, how hard it actually is, where UK buyers should purchase, and how it stacks up against the alternatives. Every review ends with a score out of 5 and links to the relevant head-to-head comparisons if you're torn between two brands.
One honest note before you dive in: Cases & Clues House pick is published by this site's owner, so read that review knowing who wrote it — and read the competitor reviews knowing this site's credibility depends on treating them fairly.
