Play the Puzzles.
Learn the Frameworks.
Many puzzle sets are built on real reasoning frameworks — from logical fallacies to systems thinking. You can jump straight into puzzles or explore the ideas behind them.
Practice trains your intuition. The frameworks explain why it works.
Attacking Faulty Reasoning
Based on T. Edward Damer's taxonomy of logical fallacies. Every fallacy is classified under the criterion of a good argument it violates. Puzzles test whether you can identify which criterion has been broken — not just name the fallacy from a list.
- Structural — Is the argument logically valid in form?
- Relevance — Are the premises relevant to the conclusion?
- Acceptability — Are the premises trustworthy and unambiguous?
- Sufficiency — Is the evidence enough to support the conclusion?
- Rebuttal — Does it address counterarguments fairly?
Each fallacy — Ad Hominem, Straw Man, False Dilemma, and dozens more — maps to one of these five criteria. Players who can name the violated criterion, not just the fallacy, earn higher scores.
Systems Thinking
Based on the work of Donella Meadows, Peter Senge, Jay Forrester and more.
Puzzles that train you to see the structure behind the symptoms. Players read real-world scenarios and identify which structural pattern — feedback loops, delays, shifting burdens, eroding goals — best explains what's happening.
The key skill: moving from event-level explanations ("the manager should have been stricter") to structural explanations ("the incentive system rewards speed over quality, creating a reinforcing loop that degrades output over time").
- Scored on 4 axes including Structural Framing — event-level thinking earns zero even if the rule name is correct
- Strong answers distinguish between confusable patterns and name the diagnostic question that separates them
- Scenarios drawn from business, healthcare, policy, and everyday life
Frameworks → Puzzles → Scoring
- Each framework defines categories, rule groups, and individual rules
- Puzzle questions link to specific framework rules they test
- The Learn section lets you browse the full taxonomy alongside the puzzles
- Bonus scoring axes can reward naming the specific rule
- Frameworks and scoring rubrics are also used to generate new questions with AI
- More frameworks are planned — the data model supports any structured body of knowledge
