A night in for two — or the perfect gift
Cold cases make a brilliant gift for the mystery-lover in your life — a night in for two, or a puzzle to unwrap solo. Digital editions can even be sent straight to their inbox with a personal message, scheduled to land on the big day and opening to a cinematic reveal.
FAQ
Pour en savoir plus, consultez notre page d’aide et FAQ.
How do I receive my cold case file?
The moment you buy, you're given secure access to your case portal — sign in and reopen the dossier to examine, download or print every file. Choose a physical edition and a beautifully made boxed kit is also posted to your door.
How many people can play?
Play solo, or team up with a partner. Cold cases are a one or two-player investigation — ideal for date night or a quiet night in.
How long does it take?
Do I need to print anything?
Not at all — you can examine everything in your case portal on any device. Print the files if you'd like to spread the evidence out, or work from the posted kit with a physical edition.
What if I get stuck?
Every case includes a built-in hint system and a full solution, so you're never truly stuck.
Can I play it more than once?
Each case has one solution, so the reveal lands hardest the first time. Plenty of detectives go back through the evidence afterwards to catch what they walked straight past — and when you're ready for a fresh investigation, there's a whole library of cases waiting.
What device should I use?
For digital editions, a computer or tablet is best for examining the documents and photographs in detail. Physical editions come ready to spread out on the table.
