The Best Family Murder Mystery Games (UK)

Detective games the whole table can play — ranked with honest age guidance, because "family-friendly" on a box and a crime-scene photo in the envelope are two different things.

By the Murder Mystery Case Files UK team · Updated September 2026

Age guidance matters more in this genre than almost any other. Most case-file games are cold-case murders, complete with autopsy notes and crime-scene photography — brilliant for teens, a hard no for an eight-year-old. The good news is that publishers have noticed, and there's now a real ladder: mysteries with no death at all for younger children, "PG-13" cases for tweens with an adult at the table, and full cold cases once everyone's old enough. Here's our shortlist, with an honest age steer on every pick.

Ages 8–12: mysteries without the murder

1. Cases & Clues — Hidden In Plain Sight (Young Detectives) House pick

The top family pick is published by this site's owner, Cases & Clues — that's what the House pick pill means. Hidden In Plain Sight was built for a real gap: children who want a meatier, evidence-led investigation without jumping straight to autopsy reports. It's a UK-made case file folder scaled for young solvers — real deduction, age-appropriate stakes — and the Detective HQ hints portal gives a parent a quiet way to keep the table moving. Priced around £24, with a 60-day money-back guarantee if it doesn't land with your kids. Available from the Cases & Clues Family Night collection; the labelled review explains the conflict-of-interest rules it was written under.

2. Murdle Junior — Curious Crimes for Curious Minds

Not a case file, but the best stocking-sized gateway into deduction we know: G.T. Karber's junior version of the bestselling Murdle puzzle books, with kid-friendly mini-mysteries solved through logic grids. It's a solo book rather than a table game, so it's the pick for the child who wants to solve mysteries on a car journey rather than at family games night. Available at Waterstones.

Ages 12–14: tweens, with an adult at the table

3. Cold Case Inc — online co-op cases

Cold Case Inc's browser-based investigations are fictional murders but avoid graphic imagery, and the co-op format works well with a mixed-age table gathered round one screen — a parent can quietly steer past anything heavy. Start with the free case, The Final Fare, which costs nothing to test on your particular 12-year-old before buying a bigger case. We'd call it 13+ as the publisher does, with sensitive readers in mind. More no-cost options in our free case files guide.

Ages 14+: ready for a real cold case

4. Cryptic Killers case files

Once everyone at the table is comfortably into their teens, Cryptic Killers' boxes (Murder of a Millionaire is the classic starter) make a great family puzzle night — the emphasis leans more towards codes and ciphers than grisly forensics, which some families prefer. Sold via Amazon.co.uk. Details in our Cryptic Killers review.

The Unsolved Case Files options: the budget way in

5. Unsolved Case Files — Honey the Bunny (ages 8+)

The family edition of the biggest case-file brand: someone has taken Honey, the class bunny, from a Year 7 classroom, and the head teacher wants it solved. It's the real Unsolved Case Files format — documents, suspects, sealed objectives — with zero violence, so children get the genuine "detective at the table" experience, and at around £19.99 on Amazon.co.uk it's the cheapest younger-kids case here — just know it's paper-only, with no digital layer or hints beyond the sealed envelopes. Kids from about 8 can contribute with an adult reading alongside; confident readers of 10+ can largely run it themselves. Our Unsolved Case Files review covers the grown-up cases too.

6. Unsolved Case Files — standard cold cases (14+)

The main Unsolved Case Files range is written for adults and marked 14+, with realistic crime-scene photos — the publisher pitches the content at roughly a PG-13 level. With older teens it's superb: three sealed objectives keep everyone honest, and the whole family arguing over alibis is the point. Around £17–£20 on Amazon.co.uk makes it the cheapest way into a proper teen cold case, though it's paper-only with no extras.
