Every detective in the world got these same crime scenes on 2026-11-07 — each difficulty published twice, once untimed and once as time attack. Each case is procedurally generated and then proved to have exactly one logical solution before it is published, including the cases where somebody is lying. You place every suspect back on the map using only their testimony: exactly one person per row, never two in a column. Whoever is left alone with the victim did it.
A 5×5 grid across 3 rooms: Sound Stage, Desert Set, Green Room. Seven statements, seven squares nobody could stand on, and enough testimony that the surplus is what pins the last two down.
A 5×5 grid across 3 rooms: Green Room, Desert Set, Prop Warehouse. Six statements, six squares nobody could stand on, and no assumption anywhere: elimination alone closes it.
A 6×6 grid across 5 rooms: Cafeteria, Backlot, Prop Warehouse, Editing Bay, Sound Stage. Seven statements, ten squares nobody could stand on, and no assumption anywhere: elimination alone closes it.
A 6×6 grid across 4 rooms: Director's Office, Sound Stage, Wardrobe, Backlot. Six statements, eleven squares nobody could stand on, and no assumption anywhere: elimination alone closes it.
A 7×7 grid across 5 rooms: Sound Stage, Backlot, Director's Office, Cafeteria, Green Room. Eight statements, fifteen squares nobody could stand on, and no assumption anywhere: elimination alone closes it.
A 7×7 grid across 5 rooms: Desert Set, Green Room, Wardrobe, Sound Stage, Director's Office. Nine statements, thirteen squares nobody could stand on, and no assumption anywhere: elimination alone closes it.
An 8×8 grid across 7 rooms: Green Room, Backlot, Director's Office, Wardrobe, Sound Stage, Editing Bay, Prop Warehouse. Fourteen statements, seventeen squares nobody could stand on, almost as many rooms as suspects, so a room claim nearly names a square, and one round of assume-and-test after elimination ran dry — and one of the eight was lying throughout.
The twist: one suspect is an accomplice — every statement they make is false.
A 10×8 grid across 7 rooms: Editing Bay, Prop Warehouse, Backlot, Desert Set, Wardrobe, Cafeteria, Director's Office. Eleven statements, fifteen squares nobody could stand on, almost as many rooms as suspects, so a room claim nearly names a square, and one round of assume-and-test after elimination ran dry.
The twist: the accusation also demands the motive, not just the name.
A 9×9 grid across 8 rooms: Green Room, Cafeteria, Editing Bay, Director's Office, Sound Stage, Wardrobe, Desert Set, Backlot. 21 statements, twenty squares nobody could stand on, almost as many rooms as suspects, so a room claim nearly names a square, and two rounds of assume-and-test after elimination ran dry — and one of the nine was lying throughout.
The twist: one suspect is an accomplice — every statement they make is false; the accusation also demands the motive, not just the name.
A 9×9 grid across 7 rooms: Desert Set, Prop Warehouse, Sound Stage, Editing Bay, Wardrobe, Backlot, Green Room. Eighteen statements, fifteen squares nobody could stand on, and two rounds of assume-and-test after elimination ran dry — and one of the nine was lying throughout.
The twist: one suspect is an accomplice — every statement they make is false.
The grid size is the size of the crime scene, so a 10×9 expert case is a far larger search than a 5×5 beginner one — but the difficulty is really carried by the clues, not the square count. A beginner case tells you almost directly where somebody stood. An expert case tells you where somebody was not, three times, and expects you to do the rest — and on half of them one of those statements is a lie told to protect the killer. If a case lists a motive, naming the right person is not enough on its own; you have to prove why.
