Murder mystery sudoku — the daily cases for 12 October 2026
Every detective in the world got these same crime scenes on 2026-10-12 — 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.
Beginner — The Botanical Garden
A 5×5 grid across 3 rooms: Cactus House, Orchid House, Palm Pavilion. Seven statements, three squares nobody could stand on, and enough testimony that the surplus is what pins the last two down.
Cracked by 12 detectives so far.
How this case was cracked — the full solution to this board, step by step
Every step below is the solver’s own — the same one that proved this board has exactly one answer. The counts are real: you can check them against the grid.
Lettered squares are objects. Nobody can stand on one, which is why the counts above are of free squares, not of all of them. B — boulder · C — cactus · S — statue
The testimony
What each person said, and how much of the board it rules out.

Petra was in column 2. leaves 3 of 22 squares
Show the squares Ada had leftThe squares still open to Ada once their own statements are taken into account — 2 of 22.
What the testimony settles on its own
Nobody shares a row or a column, so each placement narrows everyone else. Before a single guess:
Nico can only be in Orchid House (row 2, column 1) — down from 22 possible squares.
Ada can only be in Palm Pavilion (row 3, column 5) — down from 2 possible squares.
Margot can only be in Cactus House (row 4, column 4) — down from 2 possible squares.
Petra can only be in Orchid House (row 1, column 2) — down from 3 possible squares.
The answer
That leaves one arrangement, and one person who could have done it: Petra, in Orchid House (row 1, column 2).

Medium · time attack — The Botanical Garden
A 7×7 grid across 6 rooms: Visitor Center, Cactus House, Orchid House, Tropical House, Compost Yard, Lily Pond. Eleven statements, ten 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 seven was lying throughout.
The twist: one suspect is an accomplice — every statement they make is false.
Cracked by 2 detectives so far.

Every step below is the solver’s own — the same one that proved this board has exactly one answer. The counts are real: you can check them against the grid.

The testimony
What each person said. One of these 7 is the killer's accomplice and every word they said is false — but not which one, not yet.
Ursula was in the same room as the Magician.
Ursula was in the orchid house or in the lily pond. if true, leaves 17 of 40
Margot was in the same room as the Gardener.
Frida was in the same column as the tree. if true, leaves 5 of 40Show it on the boardThe squares this one statement leaves Frida: 5 of 40.

Unmasking the liar
One of these 7 people is the killer's accomplice, and every word they said is false — but you are not told which. Take each in turn: read their statements backwards and ask whether the rest of the testimony can still be satisfied.
If Helena were the one lying, no arrangement satisfies the rest. Not them.
If Ursula were the one lying, no arrangement satisfies the rest. Not them.
If Margot were the one lying, no arrangement satisfies the rest. Not them.
If Frida were the one lying, no arrangement satisfies the rest. Not them.
Another 2 candidates collapse the same way.
Only Abel survives the test. That is the accomplice, and everything they said is now read backwards.
Read backwards, Abel actually told you:
Abel was NOT beside the flower bush.
Abel was NOT north of the Diva.
What the testimony settles on its own
Nobody shares a row or a column, so each placement narrows everyone else. Before a single guess:
Margot can only be in Cactus House (row 4, column 2) — down from 40 possible squares.
The squares that had to be tested
The rest does not fall out on its own. It takes 7 eliminations of the same move: put someone on a square, follow the consequences, and watch the board contradict itself.
Put Helena in Visitor Center (row 6, column 4) and the testimony cannot be satisfied at all. So not there.
Had Ursula stood in Lily Pond (row 1, column 5), Frida would have had nowhere left to stand. So not there.
Put Frida in Compost Yard (row 2, column 3) and the testimony cannot be satisfied at all. So not there.
Put Abel in Lily Pond (row 2, column 5) and the testimony cannot be satisfied at all. So not there.
Show what goes wrongSuppose Ursula stood on the dashed square. Frida then has nowhere left to stand: every square still open to them is shaded out.
Another 3 squares fell the same way.
The answer
That leaves one arrangement, and one person who could have done it: Frida, in Compost Yard (row 1, column 3). Abel lied throughout and was never charged.

Luna was somewhere east of the Diva.
Abel was exactly 5 columns west of the Curator.
Exactly 2 people were in the garden path.
Show the squares Jimena had leftThe squares still open to Jimena once their own statements are taken into account — 14 of 75.
The squares that had to be tested
The rest does not fall out on its own. It takes 95 eliminations of the same move: put someone on a square, follow the consequences, and watch the board contradict itself.
Had Vera stood in Lily Pond (row 5, column 5), Rufus would have had nowhere left to stand. So not there.
Had Rufus stood in Garden Path (row 7, column 9), Vera would have had nowhere left to stand. So not there.
Put Nestor in Compost Yard (row 1, column 1) and the testimony cannot be satisfied at all. So not there.
Put Petra in Seed Vault (row 6, column 4) and the testimony cannot be satisfied at all. So not there.
Show what goes wrongSuppose Vera stood on the dashed square. Rufus then has nowhere left to stand: every square still open to them is shaded out.
Another 91 squares fell the same way.
The motive
This case demands the why as well as the who: naming the killer without proving the motive counts for nothing. 8 motives are in play, and these statements narrow them.
Jimena's motive would have been debts.
Abel's motive would have been obsession.
Vera's motive would have been buried secrets.
Petra's motive would have been revenge.
Oscar's motive would have been blackmail.
Whoever did it was not driven by ambition.
Whoever did it was not driven by jealousy.
The answer
That leaves one arrangement, and one person who could have done it: Rufus, in Garden Path (row 6, column 10).
The only motive left standing for Rufus is inheritance.
Show the solved boardThe only arrangement the testimony allows. Rufus is ringed in red.
How to read a case above
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.
The Cartographer’s Debt — The Botanical Garden had a false testimony and almost no one to read it — 2 tried. It takes 3 agreeing to make a charge.
Every investigation on 12 October 2026 unfolded at The Botanical Garden, offering ten distinct scenes ranging from compact five-by-five grounds to expansive ten-by-nine layouts. In standard play, the simpler inquiries saw solid progress, though demands grew as motive requirements were introduced on the hard ten-by-eight grid with seven rooms and the expert ten-by-nine board with eight rooms. A guest detective proved exceptionally quick on the standard beginner case at 0m 14s and closed the standard expert board in 4m 44s, while chentian swept the remaining untimed inquiries, logging 0m 09s on easy, 0m 33s on medium, and 4m 13s on hard.
The time attack cases drew a much smaller field of investigators, but the challenges grew sharper. A liar lurked among the six rooms of the medium seven-by-seven investigation, and motive requirements complicated both the hard and expert inquiries, which each featured seven rooms. Chentian claimed the fastest time across every timed scene of the day, finishing beginner in 0m 11s, easy in 0m 12s, medium in 1m 17s, hard in 2m 35s, and finally untangling the grueling expert case in 10m 38s, where only a single solver found success.
