About
Somebody here did it. Can you work out who?
Sudunnit is a murder mystery you solve like a sudoku. Every case is a floor plan with rooms, furniture and a handful of suspects, and each suspect tells you where they were. Seat everyone in the right spot and the culprit gives themselves away: the one person left alone with the victim.
HOW IT WORKS
• Every row and every column holds exactly one person.
• Everyone sits in a cell that fits their statement.
• Every room holds at least one person.
• The murderer is the only person alone in a room with the victim.
No guessing. Every case has one solution, and you can always reach it by reasoning.
WHAT'S INSIDE
• 500 cases across 15 chapters: lakeside cabins, a café quarter, the archipelago, a night train, a Christmas market, Hotel Aurora and more.
• A new daily case every day. Keep your streak going and climb the detective ranks.
• Every chapter has its own map, its own jazz and its own fiendish boss case.
• A bigger mystery in every chapter: collect evidence from the cases and name the culprit on the evidence board.
• Weekly goals, stars and rewards.
• Hints show you the next deduction without giving the answer away. Your first hint each day is free.
• The first three cases walk you through it.
COZY, NOT CREEPY
No blood, no gore. Just clever clues, charming suspects and the kind of mystery you can happily solve over a cup of tea before bed.
