Masters of Mystery review: the biggest menu in murder mystery
Masters of Mystery sells everything from 20-player themed dinner parties to solo cold case files, in both instant-download and boxed formats. We look at what's genuinely good — and where the prep work piles up.
4 / 5
Our verdict: the best one-stop shop for hosted murder mystery parties in the UK, with a huge theme catalogue, wide player counts and a clever randomised-culprit system. Its solo cold cases are decent but not its strong suit, and the digital versions can mean serious printing homework before the party starts.
What is Masters of Mystery?
Masters of Mystery is a UK-facing murder mystery publisher with an unusually broad catalogue. Where most brands do one thing — a boxed evidence case, or a scripted dinner party — Masters of Mystery does four: themed dinner party games for roughly 4–20 players (around 37 titles at the time of writing), Cold Case Files for solo or two-player sleuthing (around 10 cases), Unsolved Trails — UK-only, self-guided outdoor mysteries through real British cities — and a set of online escape rooms.
Games start from £24.95 and come two ways: instant digital download with a free companion party app, or a physical boxed kit posted to your door with printed booklets and sealed evidence. The headline trick is replayability — the culprit is randomised each play, so a kit can be run again at next year's party with a different solution. Among the brands we've reviewed, that's genuinely rare.

What it's like to play
The dinner party games are the heart of the brand: guests each take a character, follow round-by-round host materials, and work through accusations over an evening. Reviewers consistently praise the clear instructions and well-organised materials — hosting is about as painless as scripted mysteries get — plus the costume suggestions and character design that help guests commit to the bit. Themes run from classic 1920s glamour through masquerade balls, Wild West, wizarding schools and a Bake Off-style tent, so finding one to match your party is rarely the problem.
The Cold Case Files line is closer to what this site usually covers — evidence-sifting detective work in the style of Unsolved Case Files or Cryptic Killers. They're solid, story-led cases, though if pure evidence-on-the-table sleuthing is what you're after, the specialists still edge it for us.
Reviews and reputation
Masters of Mystery advertises a 4.7-star average from more than 11,000 verified-purchase reviews on its own site , and holds a strong-but-lower 4.4 on Trustpilot from roughly 1,100 reviews at the time of writing, with around 83% five-star ratings and the company actively replying to negative feedback. The pattern in the reviews matches our take: hosts love the party games; the grumbles are almost all about printing and prep on digital orders.
What we like, and what to know
What we like
- Huge catalogue — around 37 party themes plus solo cases, trails and escape rooms
- 4–20 player support: one of the few brands that handles big parties well
- Randomised culprit makes kits genuinely replayable
- Choice of instant download or ready-to-host boxed kit
- UK-friendly: £ pricing, UK delivery, UK-only outdoor trails, UK phone support
What to know
- Digital versions can need substantial printing and prep before the party
- Party games need a host who's read the materials — someone works harder than the guests
- Cold Case Files are good, but evidence-box specialists offer deeper solo sleuthing
- Trustpilot average (4.4) sits below the site's own advertised 4.7 rating
Who should buy Masters of Mystery?
If you're hosting a themed party for eight, twelve or twenty people, Masters of Mystery is probably the best UK option we've reviewed — no boxed evidence case scales to those numbers. If instead you want two-to-six people quietly cracking a case around a table, a dedicated evidence game is the better fit: see Unsolved Case Files, or the Cases & Clues House pick case file folders at around £25, which need no printing, no host — and come with a Detective HQ hints portal if the table gets stuck.
FAQs
Is Masters of Mystery available in the UK?
Yes — it is a UK-friendly brand. Prices are in pounds, boxed kits are posted to UK addresses, digital games download instantly, and its Unsolved Trails outdoor mysteries are UK-only, set in real British cities.
How many players do Masters of Mystery games support?
The dinner party games are designed for roughly 4–20 players, which is one of the widest ranges of any murder mystery brand. The Cold Case Files line goes the other way, built for solo play or two players working together.
Are Masters of Mystery games replayable?
Yes — the brand's headline feature is that the culprit is randomised each time you play, so the same party kit can be run again with a different solution. That is rare: most case files, including ours, are single-play.
Do I have to print anything?
With the digital version, usually yes — a common criticism in reviews is the amount of printing and preparation needed before a party. The boxed kits arrive with printed booklets and sealed evidence, so choose those if you want zero prep beyond reading the host guide.
