14 QUESTIONS · NO TIMER

Logic & Deduction

Follow the rules, find the necessary conclusion, and watch out for tempting reversals.

Find the useful constraint

Logic puzzles ask what must follow from the supplied statements. If every approved file has a signature, a signature alone does not establish approval. Imagine an unapproved file that also has a signature: that possibility shows why reversing a rule can fail. Keep track of whether a claim says all, some, or none. These words set different boundaries.

Slow down at the decision

Before choosing, restate what the question actually requires. Separate a condition that must hold from a detail that merely sounds familiar. Try each choice against the complete rule, rather than stopping at the first plausible answer. A counterexample can eliminate a confident guess faster than a long calculation. These rounds have no countdown: reading the explanation is part of the experience, not a penalty for a mistake.

A fair challenge

Each question provides its assumptions and has one intended answer. Pattern questions state their rules instead of asking you to guess an author's private pattern. Probability questions specify what is random and what information is known. Use the explanation to identify the exact step that changed your answer. Then try a fresh round; recognizing a principle in a different situation matters more than memorizing an answer letter.
