Online Quiz: Cryptic letters tied to cold cases

About this quiz

What this quiz explores

Cryptic letters can be taunts, confessions, misdirection, or desperate attempts to be understood—and they often sit at the center of cold cases. This quiz focuses on how these messages are described, analyzed, and connected to investigations.

Every question uses a 4-option multiple-choice format with no timer, so you can read carefully and think through each clue. Before you start, pick your question count and difficulty; “Mixed” blends easier recognition items with tougher inference-based prompts.

Skills you’ll practice

You’ll sharpen your ability to spot recurring themes, evaluate plausibility, and interpret language that may be coded, performative, or intentionally vague. The challenge is balanced by mixing straightforward terminology with scenario-style questions that require close attention.

Identifying common features of anonymous letters (tone, threats, signatures, patterns)
Distinguishing credible details from red herrings and sensational claims
Understanding basic ideas behind ciphers, codes, and obfuscation (at a high level)
Connecting letter content to investigative context without overreaching
Building careful reading habits: dates, locations, wording changes, and inconsistencies

Common pitfalls (and how to avoid them)

Many players rush to the most dramatic interpretation; instead, prioritize what the text actually supports. Another frequent mistake is assuming every cryptic message is a solved cipher—some are simply ambiguous, manipulative, or incomplete.

How difficulty stays fair

Mixed difficulty keeps momentum: easier questions reinforce key concepts, while harder ones test nuance and logic. Because there’s no timer and each question has four options, you can slow down on the tricky items and treat them like mini case notes rather than speed rounds.
