Motive: Murder Sudoku Cases

Work out where everyone stood, and find whoever is left alone with the body.

Four people were inside. One of them is the killer.

Motive is a murder sudoku. Every case is a room plan with a body on it. Each suspect tells you one thing about where they stood — and every statement is true. Work out where everyone was, and whoever ends up alone with the body is your murderer.

THE RULES, ALL FOUR OF THEM

• Each person stood on exactly one square
• Nobody shares a row or a column — not with each other, and not with the body
• Furniture blocks: a table, a plant, a bookcase and a piano cannot be stood on. A rug, a chair and a sofa can
• Every statement is true. There are no liars in this game

NO GUESSING. EVER. Every case is machine-checked twice before you ever see it: once to prove it has exactly one answer, and again to prove that answer can be reached by reasoning alone. If you are stuck, the next step is on the board. It is never behind a coin flip.

EXPLORING IS FREE You get three hearts, and only a real contradiction costs one. Place someone on a blocked square and you are simply told no. Place them somewhere the evidence does not yet prove and you are told it is unproven — also free. A heart is spent only when a placement makes one of the statements impossible. Curiosity is not punished here. Bad reasoning is.

WHAT IS INSIDE

• 93 hand-tuned cases, then an endless ladder that keeps generating
• Boards from 5×5 with four suspects up to 8×8 with seven
• Twenty-two kinds of statement, from "was in the kitchen" to "the killer was standing on a rug"
• Rings that show every square a suspect could still legally take
• Rule Out mode for pencilling in what you have eliminated
• The same case on every device: level 47 is level 47 for everyone, forever
• Fully offline. No account, no wifi, no interruptions
