New puzzle in — midnight US Eastern · solved 0 so far
Every clue is a fact, and exactly one arrangement of suspects can satisfy all of them at once. Your job is to find it — by elimination, not by trial and error.
No one can be placed on that square; some clues describe positions relative to it.
“Hugo stood right beside the table.” “Nora was west of Percy.” Nothing is misleading and nothing is probable. Tap a clue to strike it out once you have used it.
Pick a suspect from the strip, then tap a square. The sudoku rule applies: no two suspects may share a row or a column, so every placement closes a whole row and column for everyone else.
Use Cross to mark squares a suspect cannot occupy and Notes to jot candidates. When only one arrangement survives every clue, the case closes.
What separates this from most free online brain games.
Each puzzle is produced by a solver that must reach the answer through a ladder of logical rules. If it needs a guess, the puzzle is thrown away and never published.
