The Sourdough Situation

Someone has made off with the office sourdough starter. Three colleagues were in that morning, and none of them look sorry.

1. Wanda never touched the laptop sleeve.

2. Hamish never touched the laptop sleeve.

3. The gym duffel was never near the roof terrace.

4. Neither Hamish nor Wanda went near the staff kitchen.

5. Neither Dev nor Hamish went near the ninth-floor desk.

★ Whoever had the gym duffel is our culprit.

CASE CLOSED

It was Wanda, at the ninth-floor desk, with the starter in her gym duffel.

The fair play promise

Exactly one solution. Provably.

Every Alibi case is machine-verified before it reaches you: one unique answer, reachable by step-by-step deduction alone. No bifurcation, no leaps, no guessing. If you are stuck, it is never the puzzle's fault. Sorry.

And because judgement should feel like judgement: no ads interrupting your thinking, no timers rushing it, and the red stamp only ever appears when you have earned it.

How it works

Five minutes of being brilliant.

I.

Read the case

Two sentences of scandal and a handful of clues. The suspects are lying low. The evidence is not.

II.

Work the grid

Tap to mark what's impossible and what's certain. Watch the truth corner itself, one elimination at a time.

III.

Make your accusation

Point the finger and commit. Get it right and the stamp comes down. There is no better sound before 9am.

The world of Alibi

Crimes worth solving. Nobody worth mourning.

Alibi investigates the great British petty crime: the sabotaged pub quiz, the suspiciously deflated prize marrow, the leftover curry that was clearly labelled FRIDAY.

You will get to know the suspects. Gordon has been questioned four times now. Gordon is fine with it. Priya keeps excellent alibis, which is precisely what worries us about Priya.
