Each pack is a complete mystery experience — from the dramatic case file letter to the sealed solution envelope. Everything ties together. Every puzzle matters.
-
Case File Letter
A dramatic CONFIDENTIAL briefing letter setting the scene — addressed directly to your child detective. The mystery starts the moment they open the envelope.
PRINTED · A4
-
Suspect Dossiers
Three full suspect profiles — photo placeholder, alibi, suspicious details and a suspicion level meter. Each one is printed like a real police file.
3 PER PACK
-
5 Puzzle Pages
A Caesar cipher, logic grid, visual pattern match, hidden word puzzle and a final verdict form. Each one reveals a genuine clue — nothing is busywork.
SOLVES THE MYSTERY
-
Crime Scene Map
A proper architectural floor plan of the crime scene with evidence markers. Children plot clue locations and draw the suspect's escape route.
UNIQUE EVERY MONTH
-
Spot the Difference
Two comic-style crime scene panels with 8 differences to find — each one a real clue that ties directly into the mystery puzzles.
COMIC STYLE
-
Sealed Solution Envelope
The answer, sealed inside. Children only open it after completing all 5 puzzles and writing their verdict. The most satisfying moment of the whole pack.
DO NOT OPEN EARLY!

KEEP & COLLECT
Meet the teamThe Cluebreakers.
Four friends. One mission. No mystery too big. They return every month — and the more cases you solve, the more you learn about them.
Sam Park
The Leader · Age 10
Brave, impulsive and absolutely terrible at sitting still. Sam is always first to the scene — and usually first to get it wrong before getting it brilliantly right.
"Right. Let's go."
Freya O'Brien
The Brain · Age 10
Has a notebook for everything. Fiercely logical and quietly competitive — she notices every single thing, and she's usually already solved it before anyone else starts.
"That doesn't add up."
Jay Chandra
The Tech Kid · Age 9
Built a working periscope at age seven. Memorised the morse code alphabet. His backpack contains approximately forty things nobody asked him to bring.
"Actually, did you know..."
Rosa Webb
The Heart · Age 10
The quietest Cluebreaker but the most powerful. She can tell when someone's lying from three metres away. Everyone trusts Rosa — including, occasionally, the suspects.
"Something's not right."
Case CB-001 · Now availableThe Case of the Stolen Trophy.
The Championship Trophy has vanished from Thornfield Primary School overnight. Three suspects. Four clues. Five puzzles. And 48 hours until sports day.
Can your child crack the case before time runs out?

Got questions?Everything you need to know.
-
Cluebreakers is designed for children aged 7–10. The puzzles and reading level are carefully pitched for this range — challenging enough to feel rewarding, never so hard it becomes frustrating. Many families with children slightly outside this range enjoy it too.
-
Your first pack is dispatched within 2–3 working days of subscribing. After that, each monthly pack is sent in the first week of the month. Everything arrives in a sealed envelope — the CONFIDENTIAL feel starts from the moment it lands on the doormat.
-
Most children aged 8+ can work through the pack independently, though many families enjoy doing it together. The puzzles increase in difficulty through the pack, so there's a natural build. The How to be a Detective guide included in every pack sets children up brilliantly.
-
Each monthly mystery contains a hidden thread — a small detail that connects to a much bigger mystery spanning all 12 cases. Children who pay close attention will start to notice the pattern. The final case in Month 12 reveals everything. It's the reason children beg to stay subscribed all year.
-
Absolutely — gift subscriptions are available at checkout. You can gift 1, 3, 6 or 12 months. They arrive with a gift card and the recipient can start from Case 1 at any time.
-
Yes — monthly subscribers can cancel at any time with no fees. 6-month and annual subscribers are billed upfront and packs continue until the subscription period ends.
THE CASE IS WAITING.
ARE YOU READY?
Join the Cluebreakers. Your first mystery arrives within days.
