What you’ll practice

These quizzes help you review major unsolved cases, key dates, known facts, and competing theories while separating confirmed evidence from speculation.

You’ll practice reading case details carefully, spotting contradictions in timelines, and recalling investigative terms often used in cold-case reporting.

How the quizzes work

Each question has 4 answer options and there’s no timer, so you can think through details like alibis, locations, and sequence of events at your own pace.

Quiz length and difficulty vary across the set: some focus on broad recognition of famous cases, while others go deeper into specific evidence and investigative leads.

Background and context

Unsolved mysteries persist for many reasons—lost or contaminated evidence, unreliable witnesses, jurisdiction gaps, and changing forensic standards. Advances like DNA profiling, genetic genealogy, and digital records sometimes reopen cases decades later, but they can also raise new questions.

  • Focus on verified facts (who/what/when/where) before theories
  • Watch for similar names, places, and dates that can be easy to mix up
  • Expect questions on timelines, suspects, evidence types, and investigators
  • Use the no-timer format to eliminate options logically
  • Try an easier quiz first, then move to more detail-heavy sets

Tips for learning from each attempt

After you finish, review missed questions to see whether the gap was a timeline detail, a location mix-up, or confusion between evidence and rumor. Re-taking a quiz is useful because many cases hinge on a small number of repeatable facts.
