Plan your next Dupery: A Game of Solo Deduction session

Our independent guide dives deeper into Dupery’s core systems, offering observations that help you refine your deduction workflow. By comparing role behavior, reputation dynamics, and regional quirks, you can develop a flexible approach that adapts to each procedurally generated case.

01 / THE GUIDE

Category Behavior Comparison

Create a quick reference sheet listing typical truthfulness for each role category. Test it across several cases to see how reliably Underlings and Traitors deviate from expected statements.

  • Note the category label when first encountering a character; it frames how much you should trust their testimony.
  • Compare numerical clues from roles like the Mathematician with location data to narrow down evil positions.

02 / THE GUIDE

Reputation Impact Log

Track reputation changes after each arrest for a full run. Identify patterns where specific roles, like the Critic, cause larger swings and adjust your arrest order accordingly.

  • Prioritize confirming a suspect’s alignment before arrest to avoid unnecessary reputation loss.
  • Watch for roles that modify reputation effects, such as the Critic, and adjust your strategy accordingly.

03 / THE GUIDE

Procedural Layout Mapping

After three consecutive cases, sketch the grid layouts you encountered. Look for recurring placement trends that might hint at hidden design biases, even though layouts are generated anew each run.

  • Treat each new grid as a fresh puzzle; avoid assuming previous case layouts will repeat.
  • Use the notation toolkit to keep track of statements and contradictions as they appear.

04 / THE GUIDE

Region Mechanic Experimentation

Play each region with a distinct set of quirks and modifiers. Note which combinations streamline deductions and which add unnecessary complexity, then prioritize the most effective setups.

  • Experiment with different role selections between missions to discover which mechanics suit your playstyle best.
  • Take note of region‑specific quirks; they often hint at the most effective deduction strategies for that area.

05 / THE GUIDE

Notation Toolkit Optimization

Try different visual styles—color‑coding, symbols, or spatial grouping—within the crime board. Compare how each method affects your speed in spotting contradictions and making arrests.

  • Use the notation toolkit to map out suspect connections; visual aids often reveal hidden patterns.
  • Try different quirks and modifiers to find a balance between challenge and enjoyment.
