About this quiz

What you’ll do in this quiz

Every case asks you to judge motive, means, and opportunity—then pick the best conclusion from 4 options. There’s no timer, so you can read carefully, revisit details, and reason it out.

Choose your question count before you start for a quick practice run or a longer investigation session. You can also set the difficulty to match your mood, or keep it mixed for a realistic spread of easy, medium, and tricky cases.

Skills you’ll practice

You’ll sharpen your ability to separate solid evidence from assumptions and decide which facts actually matter. The quiz also trains you to compare suspects fairly instead of locking onto the first “obvious” answer.

Identifying which clue supports motive vs means vs opportunity
Eliminating suspects using contradictions and missing access
Spotting red herrings and emotionally “loud” but irrelevant details
Making probability-based choices when evidence is incomplete
Reading carefully for time windows, alibis, and access constraints

Common pitfalls (and how to avoid them)

A frequent mistake is treating motive as proof—many people have reasons, but fewer have the ability and access. Another trap is ignoring timing: opportunity often hinges on minutes, locations, and who could realistically be present.

How the difficulty stays balanced

Mixed difficulty blends straightforward cases with more nuanced ones that require combining two or three clues. If you want a smoother ramp-up, start on an easier setting and increase difficulty as you get comfortable with the patterns.
