How to Play

Read the clues. Tap a clue to pin it — the suspects, evidence and rooms it talks about light up on the board.

Drag a chip into a room to stage it. Rooms can hold many candidates while you think — drag a chip back out to remove it.

Tapa staged chip to confirm it. Right answer: it locks and the room's other same-type chips clear out. Wrong answer: the chip pops back and a False accusation ticks.

The Case

A country house. A death overnight.

The household has been gathered in the parlour, and every soul has given the constable a statement about where they were that night. Every word of it is true — but only one arrangement of people and implements fits all the statements at once.

Every room ends up holding exactly one suspect and one piece of evidence — the counts are equal on all three sides — and your job is to work out which goes where.

You're the visiting inspector. Read the rail, place every suspect and every piece of evidence into the room they belong in. When the last chip locks, the room where the killer ended up — with the weapon in their hand — marks itself on the board. That's your verdict.

A new case opens at midnight Eastern Time. Early-week files are open-and-shut; the casebook tightens as the week goes on.
