How to Create Research-Based Puzzles

Research puzzles reward curiosity and learning. Solvers discover facts about history, science, or local culture while gathering information needed to solve ciphers or calculate coordinates.

Research Puzzle Patterns

Quiz → Coordinates

Trivia answers provide digits for coordinate formula

Research → Cipher Key

Discovered name/word becomes the Vigenère keyword

Historical Encoding

Message encoded using method from that era

Scavenger Hunt

Find specific facts, first letters spell keyword

Quiz-Style Research

Questions whose answers provide coordinate digits:

Example format:

N 51° AB.CDE W 000° FG.HIJ

A = How many wives did Henry VIII have?
B = In what century was the Domesday Book compiled? (digit only)
CDE = Year the Great Fire of London started minus 1600
...

Question Design Tips

  • Single correct answer: Avoid ambiguous questions
  • Verifiable sources: Wikipedia, official sites
  • Thematic connection: Questions relate to cache theme
  • Difficulty progression: Start easy, get harder

Research → Cipher Key

Research reveals information needed to decode a cipher:

Example:

"This church was designed by a famous architect. His surname is the key to decoding the coordinates below."

[Vigenère-encrypted text]

Research reveals: Christopher Wren designed the church
Key = WREN

Key Sources

  • Names of architects, artists, historical figures
  • Place names, street names, building names
  • Scientific terms, species names
  • Historical events, battle names

Research + Word Values

Research a name or term, then calculate its A1Z26 value:

Example:

"The famous naturalist who lived nearby developed a theory that shook the world.

N 51° AB.CDE where CDE = word value of his surname"

Research: Charles Darwin lived in Down House nearby
DARWIN = 4+1+18+23+9+14 = 69
CDE = 069

Research Scavenger Hunt

Multiple research tasks whose answers form a keyword:

Example:

Answer these questions. The first letter of each answer spells the cipher key:

1. Element with atomic number 7: Nitrogen
2. Planet closest to the sun: O..wait, Mercury starts with M
(Shows importance of testing!)

Tip: Create your keyword first, then find questions whose answers start with those letters. It's much easier than the reverse!

Complete Example

Cache Title: "Local History Quiz"

Cache description:

"Test your knowledge of local history! Answer these questions to find the cache:

N 51° AB.CDE W 000° FG.HIJ

A = Number of monarchs named George
B = Century when the local church was built (1st digit)
C = Number of wives Henry VIII had
D = Year of Great Fire of London ÷ 1000 (round down)
E = Number of letters in the architect's first name (St Paul's)

FG = Year the local pub was established − 1800
HIJ = Word value of the pub's name (use A=1, Z=26, sum all letters)"

Solution path:

A = 4 (George I, II, III, IV... wait, plus George V, VI = 6?)
This shows why clear, unambiguous questions matter!

Always verify your research questions have single correct answers.

Pro Tips

  • Verify every answer. Research questions that seem obvious often have alternative answers. Double-check everything.
  • Cite sources. If using obscure facts, mention where solvers can find the answer (specific Wikipedia page, official site).
  • Avoid time-sensitive facts. "Current population" or "number of members" changes. Use historical facts.
  • Test with non-experts. What's obvious to you may be challenging for others, and vice versa.
  • Provide a checker. Research puzzles have many potential wrong turns. A coordinate checker helps frustrated solvers.
