Every detective in the world got these same crime scenes on 2026-10-27 — 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: Tee Box, Clubhouse, Green. Six statements, seven squares nobody could stand on, and no assumption anywhere: elimination alone closes it.
A 5×5 grid across 4 rooms: Water Hazard, Tee Box, Cart Path, Rough. Six statements, five squares nobody could stand on, and no assumption anywhere: elimination alone closes it.
A 6×6 grid across 5 rooms: Tee Box, Green, Clubhouse, Bunker, Water Hazard. Seven statements, nine squares nobody could stand on, and no assumption anywhere: elimination alone closes it.
A 6×6 grid across 4 rooms: Clubhouse, Water Hazard, Green, Cart Path. Seven statements, nine squares nobody could stand on, and no assumption anywhere: elimination alone closes it.
A 7×7 grid across 5 rooms: Fairway, Green, Rough, Bunker, Clubhouse. Nine statements, twelve squares nobody could stand on, and no assumption anywhere: elimination alone closes it.
An 8×7 grid across 5 rooms: Clubhouse, Cart Path, Fairway, Rough, Green. Eight statements, thirteen squares nobody could stand on, and no assumption anywhere: elimination alone closes it.
A 9×8 grid across 6 rooms: Fairway, Water Hazard, Rough, Tee Box, Pro Shop, Green. Fourteen statements, thirteen squares nobody could stand on, and one round of assume-and-test after elimination ran dry.
A 10×8 grid across 6 rooms: Green, Tee Box, Clubhouse, Cart Path, Rough, Pro Shop. Twelve statements, eighteen squares nobody could stand on, and one round of assume-and-test after elimination ran dry.
The twist: the accusation also demands the motive, not just the name.
A 10×9 grid across 7 rooms: Green, Water Hazard, Fairway, Pro Shop, Rough, Cart Path, Clubhouse. Ten statements, twenty squares nobody could stand on, and two rounds 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: Clubhouse, Green, Water Hazard, Rough, Bunker, Cart Path, Tee Box, Pro Shop. Eighteen statements, sixteen 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.
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.
